Sony TV Help

[blipblop]

Wasn't sure where to post this... but here goes.

We have a Sony TV that from time to time just cuts off picture, but you still hear the sound. It is probably about to break. I'm wondering if there is anyway to see what is wrong and possibly try and fix it? It's an "old school" non-flat TV.

Thanks

Perfect excuse to upgrade to hi-def. Just don't buy another Sony.

What's wrong with Sony?

My parents have a Magnavox TV from 1979 (yes it has an IR Remote) that does the same thing. You hit the power button and the picture turns off but the sound remains on. They just put it on power strip with a toggle.

Does your do it even when the TV is suppose to be on? If so, it sounds like time to upgrade.

Sony makes good LCD / Plasma's, but their quality isn't above the rest anymore...unlike their pricing which still is.

Sounds like your TV needs a smack on the side or back.

What isn't? Subpar parts mean it'll break soon after the warranty runs out, it'll cost more in the first place, and you're funding a company which has shown zero concern for privacy laws on multiple occasions.

Initially when I turn my tv on, it will be fine, but then after 5 -10 minutes or so the picture will disappear and then reappear randomly whenever it wants. Then it'll disappear again.

It sounds like one of two things is causing the problem.
Either a cold solder connection, usually in the power supply area or the
horizontal output / flyback area .... Be very careful when checking as
the voltages are dangerous. If you see a cold joint, you can resolder it (tv unplugged for a few hours first)

Or it could be a part that has a thermal problem, which you could isolate with Freeze Spray ... When it
cools the bad part, it will start working again. That will be the part to replace.

CRT TVs, at least, can hold a lethal charge for years after being unplugged. There's a trick to discharging them, but I'd REALLY recommend getting a tech over doing it yourself. Not worth the risk to your life in return for saving a few bucks.

I did mention being careful in my post. Myself, I used to work on tv sets, so I know how to do so safely and what / when not to touch. That said, a visual inspection with the set unplugged, may easily spot the problem area. Then proper procedures for repairing it can be used. Personally, if the set is more than 6 or so years old, I would replace it. A newer set will not be that costly, will have more features, work better, take up less space and less electric usage.

Seriously man, this is a great time for you to upgrade. Get rid of that junk, and get a new HDTV. If you like Sony, check out the new XBR8 coming out. Hopefully your budget for a new TV is $7,000 or less though.
