    RCA Flat screen LCD Model no: L26WD26D

    So i got this little gem the other day, Decided today would be a good day to hook it up to my pc as my monitor, So i went out found a double sided VGA cable to hook it up, Set it up, Plugged it in. Turned it on and was having some troubles with the button to change the input source. So i turned it off (Via the button on the top) And tried turning it right back on..... wouldn't you know it.... The POS wont turn back on. :mad:

    This TV has been sitting outside for a while (Mind you that means its rather dusty) But I know for a fact it still works. (Like i said, I had JUST turned it on and it was running right before this happened) So i took it apart figuring the contacts were dirty or something simple. Took out the button circuit board And tried turning it on via hitting the actual button on the board itself. It just refuses to turn back on. The button itself seems to be functioning fine, It goes down and up like it should and even makes a little click when you hit it. I dont have the remote for it anymore, which was how we usually turned it on when it was outside.

    The circuit board that the buttons are attached to dont really have any contacts to clean. Its just a simple little button. Is there some way to program a universal remote to a tv that you can't turn on? Or maybey some way to force the contact of the power button? The buttons themselves dont look like i could take them apart and reassemble them. They all seem to be one piece.

    Anybody ever found themselves in a similar predicament?


    I could get the original remote back but it will be a few months time. I'd really love to get it working now =/. Any suggestions would be appreciated.

    Edit: I can take some pictures with my phone if you guys would like, Just let me know.

    Check the back for a reset (circuit breaker) button. Some TV's have them. I had this issue once and there was a reset button on the bottom rear. Clicked it and all was well.

    Also, If you have it plugged into a GFI circuit, make sure the GFI hasn't tripped.

    I don't see any reset or circuit breakers on the back, But i figure there may be one under the casing. I'll have to take it off again and take a closer look. The wall plug itself is fine, Not a GFI, And when i plug the TV in the little red light (status light?) on the bottom turns on, Its getting power. Somewhere between the power button itself and the circuit board the buttons attached to im guessing.

    Its just got me stumped as to how in the hell it stopped working after i used that very button to turn it off. Now that you mention a circuit breaker though it sounds like it could very well be the main suspect in this crime.

    I was kinda of shocked it was an RCA myself MSP =P

    I'll throw some pics up when i strip it back down again later.

    Since you have it torn apart, try taking a multimeter and tracing the voltage around the tv from the power supply, and look for the tiny fuses that TV power supplies have these days. There should be anywhere from 5v to 12v going to the button board, as well as the mainboard, and there should be a few relays as well that could be checked.

    Well i've stripped it down and looked at every square inch of the thing, Checked the relay, all the fuses i could find. Everything looks fine...... I really am stumped. Either the button circuit board took a shit on me or the power supply itself. Im just stumped.

    Was going to take pics but.... theres nothing to take pics of... it all looks completely functional.

    Just going to wait for the remote to get here, If that dosent work im going to shoot the effing thing. =P

    Did you have it still hooked up to the computer? Some sets will not handle a VGA voltage on signal without blowing a cap. Look at the caps on the power board, are any bulging at the tops or leaking?.
    I seriously doubt that it's a micro button. Start at the place the power cord goes into the set and check all the capacitors and fuses. Try another input device than a VGA/DVI.
