Repair Fail of a Vintage Sony Trinitron CRT TV - White Horizontal Line Fault.

[@soerenbode]

Fascinating. Thanks for posting "fails" - 'tis the only way to learn. ;)

[@TheUltimateRecycler]

Absolutely! I have learnt lots already - but not enough to have it working yet!

[@geofft3214]

No fire, no explosions! Always a good day when that doesn't happen. 😆👍

But much better KZbin views when it does Geoff!! 🤣

[@Gubalicious]

I LOVE finding channels like this!

[@TheUltimateRecycler]

That's nice to hear! 🙂👍

[@timsampson2941]

My Trinitron was doing this intermittently. This video and the comments inspired me to replace the vertical IC and now it seems to be good.

[@TheUltimateRecycler]

Excellent Tim, well done. I'm yet to pull this TV out of storage, but will be replacing the vertical IC when I get around to it! 👍😊

[@brettweber2632]

I loved repairing these sets back in the early 90”s. Very common fault was the Vertical Output IC located on the heat sink. Also there is some times a fusible resistor that supplies power to it that can go open circuit if the Vertical IC is faulty. Good Luck. !!

[@TheUltimateRecycler]

Thanks Brett. I still have to get back to this job! Thanks for your advice 👍😊

[@SollersScrappingandDiving]

I love that capacitor tester, very handy, people often message me asking if I have come across certain capacitors or chips and that would be pretty nifty 👍

[@TheUltimateRecycler]

Given that capacitors are the most common component to fail, that tester is very handy indeed! Thanks Sollers 😊

[@unclejackstoolshed4513]

Mighty effort, Chris. You did just fine. Sometimes, just leaving a problem & then revisiting can solve it.

[@TheUltimateRecycler]

Exactly - just like doing a crossword!! 👍😊

[@shivasisdash7343]

replace that vertical ic..and you are done.If you can arrange the same part from anywhere. Because the cap you removed caused the ic to internally damaged..

[@TheUltimateRecycler]

Thanks, yep - quite a few people have pointed this out to me! I need to dig the TV out from storage and order a vertical IC 👍😃

@@TheUltimateRecycler I appreciate..your work for saving the world from e-waste

[@Tech_481]

Awsome video even if it didn't turn out in the end! I have a big 34" panasonic that I tried getting running that had a vertical collapse well I wasn't able to fix it as well but I put everything back together and I said I'd get back to it when I had more knowledge and that was a year and a half ago lol. Maybe I should bust it out and have a go at it myself!

[@TheUltimateRecycler]

Yep, it's probably time to have another go! From the responses I've had on this video, I'm fairly confident now that my next effort will be successful! I'll film it of course!

[@Tech_481]

@@TheUltimateRecycler awsome I can't wait!

[@resurrectronics]

Really interesting job! I'm too scared to touch CRTs, with the voltages, vacuums, and rays involved. I have the same component tester, I think it was reading that capacitor as 100 pF for picofarads not uF, so really no capacitance left.

[@TheUltimateRecycler]

Thanks, yeah I was being pretty careful of the high voltages! You could be right about the pF readings, I didn't look that closely! 👍

[@benlin1526]

It's so funny to think of my TV's as vintage

[@TheUltimateRecycler]

Haha, electronics become 'vintage' very quickly!!

[@jekunP]

Have you tried reflowing the three legs of the horizontal output transistor? It is a slightly larger transistor about as wide as a finger or thumb. That can also cause horizontal line if the legs break loose from cracked solder joint.

[@TheUltimateRecycler]

I'm not sure I did try that. I need to revisit this project soon - will check that out, thanks! 😊👍

[@tony359]

Nice try! The failure is with the vertical deflection, I am not a CRT expert either but there should be a transistor driving it? The CRT is a large capacitor so it retains the charge when switched off. By shorting the anode with ground, you discharge it. However, you should clip the ground to the metal tabs (or wires) around the CRT itself. This way you're shorting the capacitor. The way you did, you are shorting it through the PCB which can be dangerous. That's a lovely Trinitron BTW!

[@TheUltimateRecycler]

Thanks Tony! Good info about the CRT - I'll refine my methods now! 👍

[@afineliner740]

I remember that some old CRTs used to have a horizontal control adjustment (an adjustable pot ?) on the back of the set to control any picture roll, and if that went bung you would end up with that solid line in the middle. Obviously the newer models have done away with that manual adjustment. 👍

[@TheUltimateRecycler]

Yeah Alex, the old B&W TVs used to have horizontal & vertical hold adjustments on the back. Not sure when they stopped doing that. There are some pots on the board that may do a similar thing - maybe I should test all of those.. 🤔

[@Thomas62611]

Hi try changing the h line out put transistoe

[@buriedbits6027]

Did you ever fix it? Did you check the neck board?

[@TheUltimateRecycler]

It's on my list to get back to very shortly! Most people seem to think the vertical IC is at fault, so I'll order one soon - just need to make space on my workbench! 🤣

[@deankdx]

30yrs ago we had a TV repair man down the road that Dad was mates with, every time i went there with Dad (often to just push broken down cars into position for him to work on also) he was just resoldering pretty much every component on boards.. (older than that Trinitron generally) he fixed our home one twice before something wasn't available so we bought a used one off him that was better. not long after that, New flat screens flooded the market 68cm etc cheap. so we ended up with new ones which seemed to last until the digital set top boxes were needed and later they ended up failing (hard drives i bet now i know more)

[@TheUltimateRecycler]

Yeah, bad solder joints appears to be the top reason for failure! Closely followed by bad caps!

[@lesallison9047]

Well I don't blame you for keeping it, nice try anyway. Not sure if missed ( got a phone call halfway through) anything there, but did you check that the resistor was working correctly? When they go wrong they can over heat causing the solder to fail, the circuit board looked a bit brown there as well, if that is the case it may just need a new one. All the best. ✌♥️🇬🇧

[@TheUltimateRecycler]

Thanks Les, the unit has been stashed away for now and will be revisited sometime in the future! 😊

[@Thomas62611]

Hi try checking the vertical line out put transistor

[@TheUltimateRecycler]

Many thanks Tom! Yes - this job is still on my list to get back to! 👍👍

[@flamespear86]

There are repair manuals for these online. Vertical line has a common diagnosis flow chart aort of thing to check through.

[@TheUltimateRecycler]

Thanks for that. I do need to revisit this TV and finish the job! 👍

[@stevesje71]

That’s the final anode can be up to 24kv. Always discharge this to the tube aquadag (graphite coating on tube bowl) or tube metal frame never through the chassis. Field output will be the issue

[@TheUltimateRecycler]

Thanks for the info Steve! 👍😊

[@Robert-jf5oi]

You should never discharge the final anode (rubber cap on tube).into the chassis as you are vulnerable to damaging semiconductors ..Still watching your video, and will comment another time,and have just subscribed....

[@TheUltimateRecycler]

Thanks Robert, I appreciate all the tips I get from viewers! How should the anode be safely discharged?

Is that the one I reflowed the solder on? Do you know for sure - or just guessing?

[@zer0b0t]

@@TheUltimateRecycler Yeah probably the vertical sync IC or something around it, if you have the service manual it should say where it is. Can't tell for sure from a video and without testing because it could be something around it, so educated guesses only, please proceed at your own risk.

To discarge crt capacitor, use ground from screen, no from board. Clean all first before repair. Its very important to get a nice tv for very years.

Yep, and it fixed it! There is a follow-up video on the repair 😊👍Thanks Robert!

[@ubidoo9906]

Could the Yoke Coil be bad, I know that if it is bad it can cause an image like that. There might not be enough resistance in the yoke anymore, I know people "rewind them" to solve the problem. Yoke don't really "go bad" they just lose resistance. Hopefully that's the issue it's the only thing I can think of.

[@TheUltimateRecycler]

Could be the yoke I guess, but quite a few people have advised to change the vertical output IC - so I'll try that first (when I dig out the TV again!). Thanks for your thoughts.. 😊👍

[@martincowie4520]

Such a pity you weren't successful with your repairs... I saw movement on all 4 legs of your second fix although the other 2 legs were maybe supports? The fact you've found issues any one of which would have prevented it from working. The trips in the van might have caused some of the broken joints you found...

Yes, the support leg solder had cracked as well, which I did fix. Unlikely Martin - I drive like a grandma off to church on Sunday mornings! 😉🤣

I had Sony tv back in the early 90s. Purchase second and not long after owning it, stop working. Tv repair charge $70, he said all the solder joins were dry. only lasted a few months and repair shop had close down. Last time I every paid someone to repair anything or purchase anything other than spanners from a pawnbroker.

Dry solder joints seems to be very much a 90s and onwards electronics problem! Lead free solder is pretty ordinary!

It is not a White Horizontal Line Fault. It is vertical issue.

Yes correct. But most people with limited knowledge will search for "white horizontal line" as that describes the problem to a non-tech.
