So my 10 year old Sony Trinitron 27" Color TV (Model KV-27V10) died the other day. It basically gets no power. Pressing the power button on the TV itself does nothing. It was on a surge protector, and I even tried another known good outlet. I opened up the back and checked the fuse at the power cord with a DMM. The fuse was still good.
The TV actually died on me while I was watching it. I was nowhere near the remote, and my other components on the same surge protector were still being powered, so I found it kind of odd.
I know that diagnosis of things over the internet are very hard, so:
When a tube TV is not getting power, is it a simple or complicated (could be MANY things) fix?
Cost-wise; Should I just forget it, and buy another one? If I did, I would probably look for a good deal on a used one.
I was just hoping to get more than 10 years out of her.
I don’t think I’ve had a tv last me 10 years,. EVER.
For what it’s worth - I’ve never bothered to have a TV repaired, but I have looked into computer monitors before. It was cheaper to replace then repair. Plus, the quaility of the newer monitor was much better.
My $650 television got zapped by a falling tree knocking out the power cables to the house, and like yours it wouldn’t respond; it was as if it weren’t plugged in. Insurance would only cover it if a repairshop tried to fix it, or stated that it was totalled.
They successfully repaired it for $200, which was covered by insurance.
The picture is about 90% of the quality it used to be. A bit washed out. Fiddling with the levels (color/sharpness/contrast/brightness) helped quite a bit, but as I said, its best now is about 90% of the quality it once was.
Funny but I just gave my nine year old 27" Trinitron to my dad to use in the bedroom. It was a good TV but I’d replace with better if it had died if I hadn’t already done so.
There are a lot of things it could be and it would probably take some physical troubleshooting with a schematic to find out. Get an estimate if you can but decide if repair costs are better spent elsewhere.
Thanks for providing a part number. I’m not a TV repair tech, but do some electronics work.
Like you said there’s no way to tell over the internet, but I doubt that the tube or the basic circuits are bad. After doing a quick search, it sounds like it’s probably any of a number of discrete components in the power supply, none of which cost that much. I’d bet that a tech would just ‘shotgun’ the power supply, replacing every part that either failed or could fail in the future. I don’t know how much it would cost, but in the end I think the TV will live for several more years.
If you decide you want to get it repaired (or investigate if it’s worth it), may I recommend you check out 3 Atoms TV on Adams Ave right over 805; it’s my brothers shop.
Tell him Bill sent you and he’ll charge you 10% more.
As far as getting a professional repair goes, don’t bother. The cost of a replacement is rather low (a couple hundred), and a repair would likely be expensive. And DON’T repeat DO NOT open it up and poke around yourself. TVs contain large capacitors which, if handled improperly, can knock you on your ass and/or kill you.
