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.

[@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.

[@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.

[@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...

[@jeromestevenfaigin6059]

I haven't seen a TV repair since 1985. With the dot bar generator, too bad you didn't degos the the picture tube. It made the phosphates come alive with color and the fine tuning (or alignment) was finely tuned using the dot bar generator was for. Chroma-alignment, after all the years I'm watching this and I only did one in my entire life! In Jr. High school with a friend back then name Seth Isenberg I think? Anyway we were hanging around and watching a Zenith TV 25" color. I notice the chroma-alignment looked whacky so I offered to fix it. At that time period the TVs (25" color) had a minnie dot bar circuit card you could mount it on 2 screws so you could use them to blend the colors to a white line out of primary colors. I got caught and never did one ever! You really hit a nerve with this episode! Cheers!

[@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!

[@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.

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!

The fibrous winding tape, may just have been what they had, or it could have been to cut down on the noise. In my youth I could hear a flyback transformer, which is up there north of 15KHz and CRTs annoyed me - the fibrous wrap tape may have helped to quiet that. And I have to give a shout out to my old friend the Keithley 236 SMU - a brilliant piece of equipment, used it for years in integrated circuit testing. Thanks for the video mark, brings back memories.

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.

[@PhilipBallGarry]

Takes me right back that 😊. The crackle of the eht, keeping one hand in your pocket whilst getting the test leads in. Obviously, we always used an isolation transformer but it was still a bit scary. My old boss used a monitor chassis for re-flocking juke box turntables. The EHT lead "borrowed" from it's connection to the tube, he would wire it to a fine, steel sieve and sprinkle the flock onto a glue-wetted surface. The main piece of safety equipment was a thick rubber glove😂. Kids of today, they've no idea 😂

[@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...

[@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.

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!

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 ;)

[@joefarr3304]
