Re: T.V. turns self off

This is a common problem. May people have been noticing in the back of the television large sparks and flames are being thrown. The unit then detects overheating and turns itself off. Please report this problem to the consumer product safety commision. I beleieve this common problem with large sparks and flames warrants a recall.

Yes, the model indicated is prone to bad solder connections (among other things) at the high voltage transformer--that would be first thing to look at.

GE D52GW12 52 in. Rear Projection HDTV-Ready


i agree with you about the fire hazard and i had many feedbacks about this tv, mostly conscious about fire hazard too.

i would suggest that in light of owning a high-def tv, it would be significantly appropriate to place this in a room with airconditioning as to diminish the heat this hdtv produces.

about the issue of the hdtv turning off, if you suspect the transformer and other parts to be the reason for the tv to malfunction, why not bring it to a certified service center which handles GE hdtv. i would say that it may be a pain but as to think of the outcome, it may be worth it.

hope this helps.

I can't find auto converge choice in menu of rca 52" rear projection tv.model # R 52 WH 74.

You have 3 pico fuses by your fly-back transformer. One of them blew that controls your convergence circuit. Your TV now thinks that it is a Basic CRT set with 1 tube. Find the bad fuse and replace with a 1/2 amp pico fuse, and re-solder all the pins of your fly-back transformer. Your menu should have the convergence option again.

My tv projection television model TN50X81 turned on by itself then it went BOOM then it shut off and now the power button is blinking and the Tv won't turn on.

That does not sound good at all. More than likely something in the power board blew, such as a transformer. You will need to have a local TV repair person look at it.

Okay let me know what you think

the flyback transformer is the large black component simalar looking to a disrtibitor of a car it has a large red wire coming out of top and a black wire. On the bottom of the board it has about 10 pins arranged in a circle. this is flyback is located adjacent to the fuse.

Please respond to this same post with your model number and I will post a link along with the part number where you can get a new replacement Transformer for a very reasonable price and they will give free tech support so you can Change it yourself.

Green Flash

I had the same problem with my SONY KP51HW40. The problem started about a year and a half ago, image turning greenish, then back to normal. Then started getting worse, with the image turning greenish or reddish, and then flashing green once and continue operating normal. And finally, it got really bad with the set shutting off after flashing green several times. It would not operate for more than five minutes at a time, before shutting itself off. So my problem got to the point of needed attention and here's how my TV got fixed. I downloaded the service manual. After the TV was shutting itself off, it displayed an error code using the POWER/STANDBY LED. My TV set STANDBY LED was flasing 8 times, and according to the service manual, this means that the T8005 transformer was bad. This is the high voltage transformer that feeds all three CRTs. The solution was to replace the transformer, but I am not really good at soldering so I decided to replace the entire D-Board, which is where the T8005 transformer resides. This transformer is also called the flyback transformer. So I ordered the new board and replaced it myself. This is the high voltage (30,000 Volts) transformer, the CRTs can hold electrical voltage for a long time. If you are not familiar with TV repairing, you can be seriously or fataly injured. That is my disclaimer. After replacing the D-Board, the problem was not solved. Obviously, the SONY diagnostics circuitry read low voltage out of the transformer and assumes the transformer went bad, but they don't tell you what else could be the problem. If the transformer voltage drops, it could be because of not enough current coming into the transformer or a short in a circuit at the output of the transformer. Then thinking, if I had green flashes (not red or blue flashes), it was clear the green CRT was the culprit. I unplugged the TV set, a couple of days later I started checking connectors and noticed the CG board (the board at the end of the Green CRT; the Green CRT is the middle CRT) was a bit loose compared to the Red or Blue CRT boards. So I pulled the board out (pull down while jiggling, no latches). Clean it well. Then I slightly bent the CRT pins, very carefully, very slightly, outwards (away from the center core). I re-inserted the board and this time, it was much tighter, and the pins were making better contact with the CG-board socket. Turn the TV on, and problem solved. No more green flashes, no more TV shutoffs. The SONY service manual did not do me any favors with the diagnostics. It should've listed all possible problems, including faulty transformer, short on CRT, bad connections, cracked cold soldering, etc. Lesson learned, and now I ended up with a spare D-board because SONY parts sales are always final. No refunds.
