Why doesn't it turn on?

My TV doesn't turn on, i just got a red light on the front. Is it the main board or the side buttons that are broken?So I replaced the power supply, which didn't fix it. For the heck of it i unplugged the cables going from the main board(eax65071307) to the side rubber keyboard(EBR76306602). And the tv turned on(as normal), but turned off within a minute. I redid this a few times and had the same results. When I fiddle with the buttons on the side for the brief time the tv is on than tv would shut off. I unplugged the power going to the main board from the power supply and the screen turned on but had to picture. Sorry for the long spiel, but given these knowns what is broken, I don't want to buy more replacement parts than i need. Also i can't get the side buttons out! Any idea how to do that if it is the problem? Thanks, Tom

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

RCA led tv won't turn on

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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I HAVE A 50 INCH PLASMA TV THAT WAS GIVEN TO ME WITH NO POWER PLUG OR REMOTE . I WENT AND BOUGHT A POWER PLUG ,PLUG IT IN AND NOTHING HAPPENED . DO I NEED THE REMOTE TO OPERATE THE TV ON AND OFF/

Hi
If the set doesn't power ON, what is the use with a remote control? If it power ON properly, the power indicator light at its front panel will light up. Look for this. If it doesn't, make sure that you have got a set which has to be repaired. If it does power up, just get a remote control to operate it. OK.

Ilo LCT32HA32 tv wont turn on, no red standby light

It could be the power or main board that is giving issues...if your able pull the back off and look for a pin on connector marked PSON or PON...that is line that tells the power board to come out of sleeping and go to work, you should see a change in the voltage when the on button is pushed, if you do then the main is doing its work and its the main if you don't see a voltage change then chances are its the power board

The green light comes on then turns to yellow.

if you look at the capacitors on the boards you will find several of them that are domed or blown, these are the most likely cause of the problem. you can find replacements for any capacitor online at electronics supply stores, like radio shack but don't try them they don't supply enough different types. you can also find examples of blown capacitors by doing a search for "blown capacitor image" on any web search. unsoldering these bad caps and replacing them with identical values like 220uf (microfarradys) and say 25 v(volts). these caps have a + side and a - side the caps are marked and so is the board. hope this helps.
