Arcade Machine Monitor (Hantarex MTC900/E)

Mark repairs a dead CRT monitor from a SEGA Out Run arcade machine.

[@Hagemann666]

You don't find many techs who will rewind a transformer. This man is an artist.

[@780bpmclicktrack4]

I was a TV Tech for 40 years and never rewound a transformer. Im really impressed..!

[@grave8digger8]

Now you have find the second ;) I do the same :)

[@Durzel]

My jaw was just open while he was doing that, very impressive

[@davidleeroth805]

Mark is not only a tech, he's an electronics engineer by trade.

[@absurdengineering]

I wonder if it’s antique and/or Japanese. You can buy identical ones from China. They look old the day you buy them.

[@Mcqlfc]

Someone should interview Mark. I would love to know how he gained the knowledge in so many areas. The guy is a genius!!

[@davidsmith-ih2kk]

And he plays the guitar.............

[@biotrekker]

I never thought I'd see a man on KZbin winding a transformer for an Arcade CRT. Your attention to detail is outstanding. As are yout tools.

[@zhaohaigaogu7821]

It is the best place in the world to revive anything. It was amazing.👍

[@rogervd666gamer]

Wow, I've never seen someone rewind a transformator. You have very special tools in your workshop. Great job.

[@TechGorilla1987]

Have you seen the channel called Glasslinger?

[@rogervd666gamer]

​@@TechGorilla1987 He makes valve tubes itself. Very interesting channel. Thx.

[@ernieschatz3783]

Glad to see you had no Electroboom moments around that thing.

Makes his own circuit boards , rewinds his own transformers my god your skills are boundless. im so glad i found this channel

[@markanglin1738]

You are brilliant, Mark! It is so rare in this day of specialists to see a true Mender at work. Everything from coil winding to fabricating replacement parts for the structure; whatever is needed to return a thing to usefulness. You are talented to the extreme, yet very pleasant to see and hear. Time spent in your workshop is pleasant indeed. I knew one other like you once (my father), so I've seen enough of this to know what you are doing and how skilled you are. He told me that when he was a boy, the only toys he ever got were the ones that other kids had broken and discarded, so he starting fixing things early. I wish I would have learned more from him. I see that same level of confidence in your work, and in the way you approach and analyze things.

[@anibalartemio9110]

This kind man never ceases to amaze. In addition to having a very well-equipped laboratory and workshop, it turns out that he is soldering the varnished copper cable and I say to myself: "Doesn't he remove the varnish? And as soon as I finish my thought, he says it! Greetings from Argentina. ps, translated text listen to Google. sorry

[@welshminty]

Fair play Mark old school technician, this is how I started my electronics life doing bench repairs, but that winding machine is pure class and still does its job perfectly

[@TechGorilla1987]

@1:11 - The first appearance of the Cliff Quick Test outside of a BigClive video. Splendid!

[@MikeGervasi]

I used to repair and refurbish pinball and arcade machines. Power washing monitors was an accepted and totally fine method to remove years of dirt and dust. Of course being CRTs we had to be extra vigilant of fly back transformer voltages and not turning them up to the point where they became X-ray generators ;)

[@jasonsomerville2504]

Enjoyed seeing a repair on a CRT, takes me back 30 years in my early career,,,occasionally getting a belt from 1/2 live chassis on old TVs and monitors, to my Dads delight when I worked in his TV and audio repair shop at weekends during my formative electronics studies...Good job

[@Ampex196]

The odd unpleasant 'belt' or two is/was the best way to gain respect re. old CRT sets. They can deliver a very nasty 'bite'. Early sets with mains derived EHT could be lethal. It is foolish to mess with anything you don't understand. Nevertheless, we all have to start somewhere, and we have all made mistakes. It is just part of the learning process.

[@Gubalicious]

The intro had me. Then it turned out to be one of the most interesting repair videos I've seen for a while. Especially the TX winding. Awesome stuff 👍

[@MikeGervasi]

Rewinding a transformer. Brilliant. That monitor was in excellent shape. No burn in, good colors, and geometry was nice and straight. Moving the convergence magnets around is a beast so lucky it didn't need it

[@domasia01]

Your skills are amazing. And this old rewinding tool is a masterpiece 😊

[@dave-d]

Ah, the good old, (scary!), days. That coil winder is a real beauty. I remember the second T.V. I worked on. I was looking inside at switch on and a cap blew up in my face! I hide on the other side of the workshop too now! Still lots of tube stuff to fix but the CRT anode HT was always a great teacher of respect. I think some of the last big CRT's were up around 100kV. Thanks Mark.

[@mjouwbuis]

Large CRTs never went above roughly 30kV, because of the risk of generating X-rays.

[@imammarc]

I think you’d give Scotty a run for his money, Mate! That’s Star Trek level engineering!

[@kthwkr]

In 1997 I had a nice 19 inch computer monitor. It cost 1k$. After being ON for an hour or so the image would start to wiggle and jump. Usually a Percussive Engineering Adjustment(PEA) would fix it for a few minutes. PEA means you slap the case but only engineers are allowed because everyone else hits it too hard and breaks it. Then an hour or two later it would do it again and another PEA was required. Finally after like 6 months I was fed up. I took it apart and removed three substantially large circuit boards. Each had hundreds of components. I put on my magnifying headset and inspected. I reflowed the solder on a few suspect places and put it back together. But it still had the same issue. Took it apart a second time and this time I reflowed the solder on every solder joint. Every one! Took a few hours. Even the big clunky ones that surely had no issue but they got some nice new solder too. Put it back together and it was an excellent monitor until it eventually got replaced with an LCD. It was still working just fine but it went into the recycle bin at work. Frankly I think the recycle company just dumps them in the city dump and charge us money for pretending to recycle.

[@KetilDuna]

I'm getting addicted to your repair videos - good job, and thank you for sharing.

[@LZDEN]

excellent work Mark, love the winding machine.

[@Ampex196]

Discharging CRT final anodes to the dag braid is always fun. Very wise to keep it permanently shorted while working!

[@KaleOrton]

So satisfying to see old tech being brought back to life! Fantastic personality, to the point, and very informative presentation. Great editing too. Thank you so much, subscribed.

[@ambrosejeremiah7869]

[@ricobass0253]

What a fabulous old hand winding machine!

[@Apothekari]

Your good humored joy at your work is a joy to watch. Thanks !

[@bklynboombox]

I really admire your KNOWLEDGE of electricity!! I wish i knew a fraction of what you know! TY from NYC!❤️

[@JumbleLane]

Great to see someone carry out an actual repair as opposed to condemming it due to age and the inability to work just that little bit harder. Great work, loving your videos and I am watching as many as I can.

[@v1970lima]

Mmmmmmmmmmm, I'm glad to know I'm not the only one addictec to this channel. (LOL)

[@MrPnew1]

I love how you actually fix and rebuilt things Mark. A real technician's technician. 27:12 vertical hold - that brings back memories of trying to get good reception on the telly in the 60's and 70's

[@briandwyer9767]

I’m so glad as a curious kid with no electrical knowledge that I never took apart an old tv. Love the way you do these videos

[@3rdandlong]

Congratulations Doctor. The surgery was a success. Patient feels like a new CRT now.

[@ianhuxstep211]

This takes me back, I used to work on amusement machines and video games, Wells Gardner and Hantarex were a common monitor to use

[@robertroe1956]

Never realised you can solder through the varnish. Always learning something from your excellent channel

[@iandouceartist]

I love these videos, amazing electrical / mechanical engineer and a suberb craftsman... really impressed with his patience and skills... there can't be many like him left with our disposable society. ⭐⭐⭐⭐⭐

[@bfhfhfhdj]

Good to keep the fingers well back when discharging the CRT, if I remember correctly the charge can jump 1cm for a CRT charge of 30,000 volts. Learnt the hard way back in the day. Found a specialised discharging tool eventually, happy days.

[@mikeh6876]

I can tell you have been at it for a long time and have studied more than just electronic circuits. Rewinding a transformer is an art.

[@madtopp]

amazing just amazing i never thought i would see a electrical repairer even attempt any thing like a re-wind well done to you every tome i see a new video of your i hope its the repair on my receiver

[@MendItMark]

Hi Tony, coincidentally, I’m filming it right now! It will be the video no 21 I reckon. Not that I number them…

[@marksgmail66]

After watching many of your videos and marveling at your skill I've an added benefit. I've found a friend! Cheers, mate. Mark in CT, USA

[@douglasRbrown]

LOL, I haven't done a CRT in near 25 / 30 years! Great Video. The Transformer winding is epic!

[@chrisbartram3034]

Loved the anode discharge bit- I always did it the way Mark did, with a lead. I was accused of being soft by the other blokes in the workshop who just used to cross a couple of screwdrivers to short it!

[@hans-joachimschroder5469]

Hi Mark, I look at this footage with the greatest fun an appreciation. More than your skills its the humor and positive approach that makes your videos so entertaining. Being an engineer working in the automotive industries for more than 40 Years, this direct encounter of physical and electronics related problems is far away now in my job. So this kind of electronics adventures bring me back a little bit and I remember, why I choose this profession once in a while. Thank you so much for that, take care and don´t let the high voltages "bite" you

[@georgealibinisis4816]

Jeez I now need a winding machine, too? Great job Mark! Myself and RetroLabAthens will definetely stay tuned to your channel!

[@Rs500ybd]

Blimey Hantarex . I Used To Install these monitors and repair them for British Rail. They were Everywhere . We did The RTA Clocks As Well.

[@Rs500ybd]

Sorry R T A Rugby Time Antenna ..

[@Rs500ybd]

We Share the same Solder Sucker Rs.

[@donlunn792]

When I was a kid,in the 50s the tv engineer used to just short capacitors with a screwdriver. Yes including the “Big” one. Being interested I asked him if there was a tool to do that,he said yes there is, but when you’ve worked on Radar during the War now that really was high voltage these are nothing.😀😀 We had a PYE fully automatic 17 inch tv set. Not sure what was automatic about it. The horizontal hold always let go when we’re watching something interesting. The TV guy never did cure it. I always hoped he had better luck on the Radar. But he was a nice guy,who put up with a kid watching what he was doing.Although I kept fairly well back!

[@user-cb6fq2gx7c]

Sei in gamba , mi piace molto il tuo laboratorio .Complimenti , io sono Giuseppe .

[@grave8digger8]

I love this Old school Repairs. i have done the same on a Telefunken TV :) But without a Windingmaschine :)

[@blindscribe1679]

When your winding your own transformer you are most certainly down a rabbit hole, fantastic repair, well done!

[@carlgray6764]

Thanks mark your channel is a great watch ... i don't dabble with stuff you do/mend .. but it's fun to watch you do it !

[@brianhoskins1979]

I have just discovered this channel. I used to work in the trade, back in the day. 20 years ago now. I consider myself very competent with electronics diagnosis and repair, but I have to admit I would not even have contemplated rewinding that transformer. However, watching you do it has taught me that it's possible. The winding machine is kind of important, though. I was chuckling often at the very healthy respect that was shown for the line tranformer output, and even the self recharge capability of the tube. That is the kind of respect that can only be shown by someone who has worked on these long enough to get a jump off one. And I've been there, and I am frightened of the HT cap in _exactly_ the same way. 😂 This was an excellent repair.

[@ossianhaufe4671]

I never thought you are able to bring this sucker back to live. You are a genius 👍

[@s.wilson5675]

Well done Mark. After seeing how you dealt with that transformer, I now know you're a wind-up merchant! Hee hee.

[@GrandslamTim1]

i worked at a manufacturer that made video games in 80's that used same chassis - not the most reliable monitor ! happy memories

[@9a1cool]

Tom Cruise is a little baby....mission imposible---done! Fantastic job man!

[@ianbishop247]

Mark, as someone who has undertaken monitor repairs onsite, including in public spaces, I am in awe of the work you do. We used to swap out driver and scan boards and then repair the boards back in the workshop. I cannot believe now that I would take the back of a terminal, sometimes on the reception counter of University libraries - Defo less H&S rules around then! Fortunately for us we worked for the system manufacturer (Cifer) so was able to source all new parts so I have never had the joy of rewinding a transformer. I've dabled with LCD TV Repairs and retro electronics but hoping to do more once I move house and setup a better workshop. You and your setup are an inspiration sir...

[@santociambrone2364]

This is very amazing fix, because you replace ........rebuilt coil for the pilot transformer.................VERY COMPLIMENT FOR YOU THANK FOR YOU VIDEO

[@camhyde9701]

I could watch that transformer winding machine all day

[@antonjansenvanrensburg4145]

Way back when i use to work for LG i always took 2 long AF screwdrivers, stick one in and other one on the other going closer and close to the ground, those high voltage jumps always amused me. picked up a charged base one day and my belt buckle touched it, knocked me on my butt, 18years later and i still burn holes in my hands with high voltage stuff that i forget to discharge..

[@patrickjmorgan]

Skill! I did a similar but crude repair to my brothers central heating boiler. The gas valve was open and the gas supplies shops- not plumbers- wouldn’t sell me one because I wasn’t CORGI. Registered. I’m a lift technician, or was in the early 70’s. So, I took the potted core out and dismantled it substituting the coil with a varley one, rewinding it onto the original former and re-potting it. With tar. Worked a treat! This of course was pre snowflake times and my little brother was training for his P1/2 exams. He’s now a multi millionaire and lives in France in an old Mill! So, study accounting and you can retire at 50!

[@KevinHallSurfing]

Worked on the VIP7800 "monitors' for Honeywell late 70's Much fun, Picture was skewed so adjusted by sticking those little grey fridge magnets around the tube. It worked. 😆

[@ecc84]

I had to chuckle at the beginning with fingers in the ears as that's me when i'm doing defective 440v electronic drives, I turn them on from the other side of the room lol I'm also glad they don't make crt's anymore as that is what i started on doing in the service industry, i used to work with this rather interesting technician who would turn a tv on and put a screwdriver under the flyback transformer cap and see if he could pull a spark from the it to his screwdriver to check it was working he was a bit of a fruit loop to be honest lol

[@jpdevilliers2783]

I scrape the wire before soldering great videos enjoy watching from south africa

[@MikesArcadeMonitorRepair]

"Don't wash your telly, people." Brilliant. Gonna steal that. I fixed one recently with the exact same issue. Stole one from a Hantarex Polo.

[@T2D.SteveArcs]

Another great video mate 😃👍, the "helping hand resistor" access the b plus regulator is common in monitors, ive seen those regulators shorted a lot of times, a dead give away before you even open her up is the set will power up at lower voltage on the variac but cuts out as you increase the input voltage and the xray protection circuit triggers...

[@Lhenndyn]

90th… The worth génération of PCB…. Thanks for this knowledge !

[@J0se_Garcia]

Bravo !!!!!! il y a longtemps que je n'ai pas vu la réparation d'un moniteur a tube cathodique, et en plus la panne, le plus difficile a trouver pour un technicien une self en panne (et je sais de quoi je parle !!!), et en plus cerise sur le gâteau "Cherry on the cake", refaire une self, tout un art, tu est vraiment un as !!!!!, franchement vous les anglais vous êtes très fort, dur a dire pour un Français 😄😄😄

[@thektulu1985]

probably the most wholesome electronics fixing channel, love watching this while working from home.

[@andrewlittleboy8532]

I’m subscribed to lots of fixing it channels like this but I’ve never seen anyone able to repair things to such a level as you do. I’m watching in complete disbelief. Incredible…. Andrew

[@bigfilsing]

dont jet wash your monitor . Best advice ive heard all week :-)

[@jimbojet8728]

That was interesting Mark. Thank you.

[@crumplezone1]

You are like all us Brummies Mark a happy chappy, bostin fix bud

Very good! I m from Brazil!👏👏🇧🇷

[@ambrosejeremiah7869]

Mark keep doing what u do as I imagine my many years in an electronics lab tweaking away. Good on u

[@Retirement_Life]

Love the rewinding of the transformer. Real old school skills

[@Synthematix]

I recapped one of these with nichicon FW series caps, I tell you what after doing it the picture was bright as hell and pin sharp, these are excellent monitors.

[@PaulBakewell]

Watched many of your video over the last 2 week and I must say your attention to details is absolutely legendary. I like to get suck in and repair things like you but normally give up at the first hurdle. May be because I only got access to a multimeter these days. Keep up the great work.

[@cjh0751]

Rolls his own transformers, a legend.

[@drummerhammar]

That winder is awesome!!!

[@hoojchoons2258]

You hate the anode cap about as much as me! Used to hate the things, probably from when discharging one with a massive pop when I was learning!! I've got to recap my old arcade machine monitor soon, can hardly wait!

[@alexdelara9858]

Not as much as rewinding the transformer, but undoing the thin wiring in a way that allowed you to figure out its turns count is remarkable. Great job !

[@johnmarchington3146]

Thanks again, Mark. That transformer rewinding was brilliant.

[@MrPitatom]

Ok, wow. Mark this is NASA level repairs.

[@ccronn]

Top quality in every way. Well done.

[@fantummenelkinstruments1959]

Just look at that coil winder! Oh man! Great job, as always!

[@BobBasshead]

Well that was fun! First time that I saw someone rewind a transformer, very impressive! And a lost art.

[@JustinHornsby]

Just when you found the tx to be dud I thought nah that's it game over unless he's gonna rewind it. And you did. There's tenacious repair techs then there's *you* !

[@joefarr3304]

Watching your videos I've realised why I'm not great at repairing equipment. There is no way I would have suspected that transformer. It's a couple of lengths of wire, what could possibly go wrong with that. I need to stop assuming things. Thanks for doing these videos, they make great watching and are very educational.

[@davidgari3240]

The CRT is a giant 10 Kv capacitor, thus his craven fear. He must have been shocked (as I have) ONCE before.

[@paulwincott2987]

The man's a genius with the patience of a Saint, love it!

[@xpump876]

We understand the concern for safety as being zapped by a flyback is a memorable experience never forgotten!

[@user-nt4px3py3l]

I used to remove HT connection from the CRT with a loop of a nylon (kite) wire once round the connector , pull it tight it then should pop out of the CRT without damaging the conductive inner of the glass CRT connection (of course discharge the HT first like you did)

[@davewatts3008]

Don’t jet wash your tele, people. Life changing advice, right there! 😉

[@Kasetpitajadul]

owesome your equipment ,like osiloscope,winding cable and etc like lab electronic!

[@Leon-qc7fe]

I worked on stuff like that for 40 years. The fast and simple way to start is to check the collector of the horiz output transistor for a short. If no short connect power to the monitor and check for B+ voltage at the collector of the horiz output. If ok the drive signal is likely missing. If no B+ go back to the power supply. That transformer you repaired is the horiz drive transformer .The horiz osc comes from IC 2 to the base of TR10. Another thing to be aware of when you work on monitors like that is they may require sync from a video signal to turn on the horiz osc. NO video signal connected the monitor may not come on.

[@PoppinWheeliez]

In every other video, I am very impressed with your capabilities. You possess a deep wealth of knowledge and experience. Thank you for sharing.

[@ccronn]

Your a goddamn legend, Mark...

[@SidebandSamurai]

Brilliant video, never saw a technician actually take apart and rewind a transformer. that winder was really cool. Great work! I subscribed to see more.

[@Justplast]

Love the old winder

[@FUNKINETIK]

Really enjoyed every minute. Yep definitely a fondness for crt tv. The coil winding was so interesting, the machine looked Victorian in a nice way,

[@MicheIIePucca]

wow.. so cool to rebuild the primary and secondaries of that transformer. I love the winding/unwinding machine too. Actually quite easy to build a transformer with the right tools.
