Question about Sony Televison & Video
I have an older Sony KV2649r 26 inch console television.When you turn it on it will work ok for about 3 minutes.Then it cuts off.If you wait about 5 minutes it will turn on again.I replaced thp-601.The old one was heating up a lot.The new one is not as hot when the set is on but it didn't fix the problem.Any other ideas what is making it cut off?When the inside temperature is low it seems to work ok but when it is warmer inside it cuts off.Thanks.Bill.

This sounds like a protection system cutting in. This happens if there is a major fault and continual use would lead to a fire risk.

SOURCE: Samsung DLP TV shuts off
I had the same problem with my Samsung 52" HDLP set turning off by itself. This is a common problem with the Samsung sets and I followed the advice I found online and believed it solved the problem. Remove the lamp cover in the rear of the TV (usually held on by one screw). There is a thermal cut off switch that is activated by the depressing of it by the cover. Factory installation for some reason was not done properly and the switch would not be fully depressed causing the set to shut off.After removing the cover, relace it by seatng the bottom of the cover first to depress the switch and tilting the top of the cover in to close it. Replace the screw &you are done. My set shut itself off for 8 Months before I found this fix. It hasn't shut off since. Good Luck

SOURCE: RCA 24V414T KEEPS TURNING OFF
it could be a ghost but most likely a bad solder connection , crystal(controls the eprom)(menu chip) , or the eprom chip itself will need to be replaced

It is the color wheel, inside the light engine. The bearings get dirty and makes it harder for the wheel to spin causing that whin.
