Mitsubishi CT-2517BM. Vintage TV set

[@mervace]

That’s a great story Michael, back in 79. I brought a cattle trailer load of ex rentals from Scotland to N.Ireland. Fixed them all in the cattle shed and they funded my 8 week trip round the USA in 1980. My parents always encouraged me to work on what ever I choose to do back then. Heading for the ferry late at night and getting onto the main Rd, the whole plant got into a speed wobble and only for my brothers calm response it could have ended badly. Great videos and memories there Michael 😅 oh this was meant to be for the story of your first colour TV

[@Synthematix]

Mitsubishi made epic sets. I was a BIG fan of their computers in the mid 90's too.

[@michaeldranfield7140]

The CRT has stood the test of time, unlike most Mullard stuff.

[@TurboTel68]

Seeing the name ‘Seme’ in that catalogue brought back some memories! Used to get all my line outputs from them and iirc they used to do some handy little repair kits for power supplies and common problems part kits. Those Pace irons are a fantastic piece of kit, I’m still running a Pace SensaTemp👍🏻

[@michaeldranfield7140]

I bought a lot of stuff from SEME back then , even had a tour the place in Melton mowbray and one of the directors took me for dinner at a local pub, however when they got involved with NEDIS they went down the pan and I ended up closing my account when I accidentally ordered 1,000 scart leads instead of 100 and they wouldn't take them back . Bought the Pace MBT250 well over 20 years ago and its used every day, never gone wrong yet but I have had a few new irons and desolder tools.

[@TurboTel68]

@@michaeldranfield7140 I don’t think I was still repairing brown goods by the NEDIS days. I’d moved predominantly to repairing just white goods by then although we were (and still are) renting televisions out, with everyone wanting flat screen stuff all our CRT stock went to the bin fairly quickly. Always found SEME helpful, I can never understand suppliers causing ill will with customers, always seems somewhat of an own goal😔 Did you manage to shift all the scart leads or are you still coming across them? I did a similar thing once with Numatic vac bags but luckily they were always a fast mover and I did get a good quantity discount!

[@monteceitomoocher]

Quality in that television, very well made, and a really good crt as well, sadly Mitsubishi are no longer with us but their products remain as a testament to Japanese engineering and quality at the time, great video.

[@stickytapenrust6869]

They are still around, they just make cars now.

[@monteceitomoocher]

@@stickytapenrust6869 Yep, i suppose i should've qualified that comment, they made planes back in ww2 as well!.

And Mitsubishi is not a name that has been resurrected yet by Vestel .

[@robtitheridge9708]

We had two of these out on rental but your video is the first time i have seen the inside. just shows how good they were

[@michaeldranfield7140]

First time I have seen one for donkeys years too.

[@drcrusherdata]

This set is from 1987-88. My grandad had this exact set.

[@michaeldranfield7140]

Should bring you back happy memories then , I always thought scart was a 90s invention but seemingly not .

[@markpirateuk]

I remember these sets, they date from the late 80's, very reliable & had a really sharp picture, certainly better than the Sony Trinitron of the same era. Those little switches plague a lot of equipment, but very cheap, so well worth replacing all of them.

[@michaeldranfield7140]

Right pain those little buttons , especially in Samsung when they go leaky .

[@Televid4]

Excellent Repair Micheal. Nice to see this Mitsubishi TV come back life. I see that you also have a Sharp VC9300 VCR machine in the video. Would be you restoring that VCR? those Sharp VCRs were very good and reliable. i used to have one and it brings back memories. Thanks Micheal...

[@michaeldranfield7140]

Not sure about restoring the Sharp VC9300 but yes I will be having a go at getting it going, dont know what I will do if the reel motor is faulty though.

[@michaeldranfield7140]

VC9300 repair is underway, video coming soon .

[@PertinaxPertinax]

Michael, great video as always - suggestion - some educational videos on using test equipment in fault diagnosis would be great such as using the scope and sig gen? regards Nick

[@michaeldranfield7140]

I will keep it in mind for the future .

[@kendom33]

Very interesting as usual Michael thank you. We had a similar one but i seem to remember that the table top stand was motor driven to chamge its orientation !!

[@michaeldranfield7140]

They may have come with a motorised stand as an optional extra I cant remember now .

[@JonTheComputerDoctor]

I don't remember repairing many Mitsubishi TV's either, great video thank you.

[@glpilpi6209]

I didn't do many either but resoldering that line driver transformer was a must but an easy fix . Mitsubishi made good reliable sets that lasted. Shame they eventually left the UK market.

[@michaeldranfield7140]

think the problem was we had no Mitsubishi dealers round here and the odd few sets I did repair would have come in for repair from people moving to the town out of the area.

[@samsscia]

Good Video. I used to do in home service on Mitsubishi Direct View and Rear Projection. The CRT units were heavy CS-35805 and CS-40805. One of the most common problems were 2 47uf capacitors on the PIP Boards. The good old days.

[@michaeldranfield7140]

The good old days when you could do repairs in a customers house.

[@gpo746]

Great video there Michael, Friend of mine had a Mitusbishi , can't remember what model, but it had two metal contacts above each channel indicator that you lightly touched to change channel . He was a heavy smoker and it was funny watching the set change channel on its own every now and then due to the nicotine on the contacts conducting across . I was only 14 and figured out it was the contacts . Later on he had a new 90's Mitsubishi video rigged up to it and used the video remote to change channel.

[@michaeldranfield7140]

I remember one or two different sets that had the same problem with touch channel selection , nicotine seems to be electrical conductive and for this reason cleaning around the anode cavity in smoker sets was an essential part of a service.

[@roberthorwat6747]

I remember the Blue Diamond Mitsubishi sets. Very distinctive blue screen. Very modern looking and stylish.

[@michaeldranfield7140]

I think it must have been a Mitsubishi patent as I don't recall any other sets with a blue faceplate .

[@f.k.burnham8491]

I loved the 32" CRT Mits TV sets. They were a cosmic cash cow for me. They had the "fish" caps in them and I if I remember correctly, I had to replace 52 'lytics on the chassis. The shop would stink for 2-4 days after working on one. That rotten fish smell was nasty. I am glad they finally got the bad electrolyte formula corrected in the ' lytics. I also soldered up any suspicious joints IIRC. that red slash under the big IC indicated a factory reworked chassis. Please correct me on this if I am wrong.

[@kahlid-ataya]

you are 💯 correct the caps were a major issue

[@michaeldranfield7140]

Sorry , I don't know about the red slash but I do remember lots of Toshiba sets that had red coloured capacitors that use to leak electrolyte and stink, most common causing frame faults in Toshiba .

[@kahlid-ataya]

@@michaeldranfield7140 i also suffered from those caps as well in the Toshiba TV's

[@Ped0772]

You'll have to do something on the Philips CP90/110 chassis...fixed hundreds of them back in the day!

[@michaeldranfield7140]

These were the first sets where I learned to do surface mount, unfortunately I don't have any of these Phillips sets .

[@michaeldranfield7140]

Actually I got this wrong it was the G90 I think the chassis was that was the first to use surface mounted components, psu blow up was common due to dry joints on smd components .

[@Ped0772]

@@michaeldranfield7140 Never seen G90's in my shop for some reason, it was all CP90 & 110's. Always with a TEA1039 with a crater in It! , we used to get repair kits, I think from SEME

[@manolisgledsodakis873]

Interesting, thanks

[@michaeldranfield7140]

Thankyou .

[@whitesapphire5865]

Speaking of Mitsubishi tellies, I have one that I had from new..... It's never been repaired, never even had the back off. I gave it to my dad about 2000, and he used it right up to his death in 2008. It's been the most reliable telly I've ever known, and I still have it, along with its original remote control. I still have that Panasonic waiting to see some leccy juice, if I can ever get out of this awful situation that is.

[@michaeldranfield7140]

Everyone says there were the most reliable sets ever made , I never found the Panasonic service manual you wanted but I may have another model that uses the same chassis .

[@iancooper2338]

nice work again MD 👍

[@michaeldranfield7140]

Thankyou , more coming soon .

[@robertball2741]

Nice job Michael!

[@michaeldranfield7140]

Many thanks .

[@paulsanderson8804]

Great repair work I suspect that people who still use these old TVs are senior or elderly because younger people need the apps and the modern flat screens big monsters sets. But still they are good sets to have

[@minimaxxl8]

These CRT TV`s are actually very popular at younger people for vintage computer-gaming.

[@michaeldranfield7140]

As someone else has commented CRT sets are in big demand with the retro gaming community and besides new flat panel sets no longer have analogue built in .

[@truthreigns7]

Hey Mr. Michael, thank you

[@michaeldranfield7140]

No problem , more stuff coming soon !

[@truthreigns7]

@@michaeldranfield7140 Looking forward to it.

[@richardh100]

I remember back in the days I used to do a rocking test the other engineers thought I was daft told them it was for dry joints 😮I couldn't be the only one I've done this😊

[@richardh100]

mitsubishi's where Great TVs I remember one can't remember the model number had a motorized base you can control it with the remote it could turn the tv left or right

[@michaelmcdonald2348]

I used to see a fair amount of Mitsubishi sets in the 90's. Very reliable once the few stock faults were dealt with. Some of the 90's models were let down by the Videocolor CRT's that had a short life.

[@michaeldranfield7140]

Luckily this set was not fitted with the videocolour CRT , the picture is a lot better than it looks in the video .

[@jasejj]

Always liked the styling on the early '80s Mitsubishi stuff, always seemed a cut above your typical Japanese designs. Quite innovative as well - not sure why they never really sold all that well as they were generally reliable and not overly expensive either.

[@michaeldranfield7140]

Certainly stood the test of time .

[@georgeprout42]

I remember buying a Mitsubishi TV and a VCR in 89/90, from Currys. I also remember ordering the service manuals for both at the till. That wasnt unusual in those days. They arrived a few weeks later through the post. A few years later I lost the devices in a divorce but kept the service manuals. Sadly I also remember having a clearout a few years ago and really kick myself for not scanning them and making them available online.

[@mattsan70]

your well shot of her - lets hope the TV went bang

[@michaeldranfield7140]

Luckily Im not a person who throws a lot away and I kept all my service manuals , never thought I would be repairing CRT ever again yet here I am ! I wonder if the Matsui stuff from Dixons/curry's was a take on Mitsubishi to try and deceive customers ?

[@electronicwaves]

What is the failure mode on those switches? If it is just oxidation, wouldn't it be possible to recover them using contact cleaner like Tuner 600 or deoxit?

[@michaeldranfield7140]

I would imagine its oxidisation due to age but there so cheap there was no point in trying to repair them .

[@gainmaster1]

Mitsubishi made serious equipment, not just TV's

[@michaeldranfield7140]

They did yes

[@xyredmax]

Hello MD. I can recall being able to clean a few quid into every repair in the 1970's and 80's, mainly due to customers being smokers! Did we ever see the circuit of you Cap reformer or was it in a magazine?

[@michaeldranfield7140]

The basic circuit of the cap reformer was in Everyday practical electronics July 1995.

[@xyredmax]

Morning. I took a look, thank you. I know these circuits are usually simple, but I wondered how your LED comes on once reformed?

[@michaeldranfield7140]

@@xyredmax It doesn't indicate the cap is reformed, the magazine says start with a 20k resistor then switch down to a 5 k resistor after a period of time , I added a bit of my own circuitry so there was automatic changeover from 20k to 5k when the charge on the cap is at 70 percent of its rated value , I reduced the output of the reformer so it only gives 250 volts and the resistor changeover occurs at approx 170 volts, the green LED is only to indicate change to lower resistor has occurred.
