RCA D52W20 TV powers on fine, then shuts itself off after 5 - 10 minutes. After 20-30 minutes, I can turn tv back on, but then shuts off again in 5 minutes.


it looks like the problem is in the 16v line..try to take it apart..and there's gonna be a 2200mf cap leaky.
that will solve your problem.

Pioneer plasma pdp4214hd shuts off after being on for about 20 min.


Are you able to turn the TV back on immediately or do you have to wait? If the TV is consistently shutting off around 20 minutes, this may indicate an overheating issue. It is possible that you need to clean the TV out of dust or it may mean your cooling fan is dead or not revving up when the temperature rises. If you are not able to turn the TV back on right after it shuts off, overheating is likely the issue, as you would be forced to wait until it cools down. If you are able to turn it back on, for how long? Does it continue to shut off after another 20 minutes? It is possible that the thermal sensor on the mainboard is defective, or that the software that controls the sensor maybe corrupt. Service or a firmware update may resolve this. You would have to contact the manufacturer.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Sony LCD Projection TV turning OFF!!!


I also have a Sony KDF-42WE655 42" Lcd television. We just changed the lamp (bulb) several weeks ago and has noticed that everytime we turn on the television it stays on about 30-40 seconds then cuts off. After about 15-20 seconds it cuts itself back on. Weird!! It must have something to do with changing the bulb!?!?

Samsung HCM4215W,shuts off.


Sounds like a short in the power wire, it takes about 10 to 15 minutes to warm up then shorts out and when it cools down you can watch for 10 to 15 more minutes before it shuts off again, you need to take it in and have the powercord replaced because this is very hard to do from home and one mistake can make the whole tv not work.

Lamp problem?


your picture processor is broken. we have the same tv, after 1 year problem started. we got a tv tech out and he looked at it and said it would cost $1800 to fix and this is after we bought a $400 bulb from sharp. this problem is in many of the same tv's of this exact model as we've invstigated and sharp is unwilling to help. there should be a classaction suit or recall for this exact tv.do not buy bulb , it will not work

the problem may be due to dry soldering in the power supply stage if it was with the lamp there would be red or green light showing the presence of the power to the tv after making it own some of the components get hot and it will make the the soldering point conectionless and after some time the heat sink get cooled and the soldering point gets connected and u will see the picture again it is a simple problem if u have a soldering iron u make it hot and re solder all the components in the first part of the circuit board and the problem if rectified
