T.V. turns self off

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.

hi

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.

The magnetron is the other issue, high voltage diode will sometimes crack causing a high level short, the capacitor developes a dead short across the 2 points, the power transformer almost never fails, "very rare"

If you sparked a wire connector at all, there's a good chance you blew the fuse for the 24 VAC transformer. There may be a fuse holder for the transformer on the box that has all the control and T/stat wires. If you can't find one then it's internal to the transformer and you'll have to replace the transformer.

If you did not turn off power and or have a hot wire touching a common wire you blew the transformer. There is a possibility your air handler has a 3 amp fuse on a control board. Check it first. If it is OK,replace the transformer.

I've had the same problem with a 32" model LC320EM82S. All the Emerson TV ( no matter what size ) are having the same issue.
I'm sure with your TV, the green light is blinking before the TV automatically turns OFF. Basically, the TV is trying to power up the screen and has failed. Protection mode turns the TV OFF to prevent other parts from being damaged inside.
My solution for fixing my TV was replacing one bad inverter transformer of six on the Backlight Inverter/Power Board. Here is what my board looks like:
You can see the six inverter transformer on the bottom of the board. It's what supplies power to the screen. Your board may look similar. You can sometimes find a whole replacement board over the internet for a good price. Shopjimmy.com is a good place to start. Just start searching by your TV model number.
If you have some electronic experience, you can repair the board itself by finding a Service Manual over the internet for less than $20. It will have all the part numbers, schematics, and diagrams you need. I would investigate the inverter transformer for your problem.
I hope I helped you out with your problem.

More than likely it blew the fuse in the transformer, although it is fairly easy to replace this fuse it is important to find out why it blew. The transformer is under the machine and held in place by 4 screws. Take this out and ease the transformer out, it will still be hooked to the connecting wires just gently disconected them. Once you open the transformer you will see a small fuse, you can take it to radio shack and get an EXACT replacement.
I have fixed 100s of these of the last 25 years

Shorted power supply/module is most likely problem.

I have A tech coming out tomorrow. It sounds and smells like the power supply board. Is there parts still available?

How do I know if the transformer went on my tv I saw a rd light & then it smelled like wire burning & the tv shut off & won't go back on. Haier 40 inch hd
