I have a Sony TV that has a really bad habit of turning off at random times while your watching it. Sometimes it will stay on for a half hour or an hour but other times it will only stay on for about a minute. I tried using a surge protector but that didn't help. Anyone have suggestions as to why it may be doing this?

(plea for help deleted and ignored) Hey, consider it a blessing. A few years ago my TV went on the fritz and I didn't bother to fix it. Haven't gotten as much reading and other stuff done before or since.

I'd rather suspect something in the power supply is getting a tad too
warm and shutting itself down. (Don't some regulator chips have
tempurature protection circuits?) Or, there just might be a "cold"
solder joint somewhere.
Undoubtedly, some techno-wizard will supply the correct answer, and
soon.

Sorry couldn't resist. Does your TV have a sleep switch? Sometimes I hit mine by accident, one hour later zap it turns off. I'm not saying you're hitting it by accident but maybe your remote control is faulty and setting it off or maybe the sleep circuitry is faulty. My Sony has a sleep light on the front to say that it is on. But, something could be wrong with that too. Ask Sony they are usually good at selling schematics or giving tips.

If it has a remote control, the following story may be of some help. I used to get cable (back when I lived in town) and had a remove control cable box. It would occasionally change channels on its own. Replacing a defective flourescent light in the room cured the problem. If you know where the remote sensor is, try covering it with something for a while and see if it is still stopping. -- John Moore HAM:NJ7E/CAP:T-Bird 381 {ames!ncar!noao!asuvax,mcdphx}!anasaz!john USnail: 7525 Clearwater Pkwy, Scottsdale,AZ 85253 anasaz!john@asuvax.eas.asu.edu Voice: (602) 951-9326 Wishful Thinking: Long palladium, Short Petroleum Opinion: Support ALL of the bill of rights, INCLUDING the 2nd amendment!

Could be a power supply problem related to the flyback - switchmode. Try powering the logic stuff of a separtate supply for a while and see what happens.
