SOURCE: RCA BIG SCREEN TV WONT TURN ON HELP !!!!!!!!!!!!

Try unplugging it for about 30-60 seconds, then plug it back in and before you turn it on, make sure there is a good video source going to the TV either from Satellite/Cable or a DVD player or something.

If this doesn't work, try unplugging it a bit longer and then plug it back in and try again. If it still does not work, you may have to take it in and get it serviced.

Usually when devices power themselves off like that, there's something wrong...

I hope this helps :) Good luck!

Best Regards,

James

It can be due to unstable DC power from the power supply due to bad caps, or bad main board (I had to replace my main board, and later on the inverter boards). You may want to think about putting money into this TV.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

Tv wont turn on. The led light comes on when plugged in it buzzes' and then nothing . Led stays on no picture sound or anything. None of the capacitors are blown. ? rca model number L26wd12


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

My tv is not CRT is LCD RCA Model L26WD12


Assuming you are not accidently sitting on the remote, I would say either the power supply or main motherboard has failed. Time for professional service or a new TV.
