Question about RCA L37WD12 37 in. LCD HDTV

1 Answer

L37WD12 turns off by itself after 15 minutes.

I have a L37WD12 that turns itself off after about 15 minutes. People have told me it may be the power supply. I unplugged it for a few hours like the manuel says but still have the same problem. The set is just over a year old. Can someone please help????

RCA TV will turn off by iteself and come back on by itself like every few minutes.


Hi!
That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board

After replacing blown capacitors...it should work again.

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Hope it helps

Need a power supply for RCA L37wd12


This power supply might not be manufactured anymore or the only place to find it is by calling RCA but that is a pricey board. You can also check this website and ask them if they have one. It appears like they do not have stock but you can call them just in case they have not updated the site.
I can also help you in repairing the defective power supply if you still have it. Write to jah2mil@hotmail.com if you need further assistance.
