I've picked up an LG 55ec930v set, won't turn on. Press power on Remote, relay clicks, LG logo lights up, led on main board lights for around 2-3seconds, relay clicks and powers off. Have forced power supply on with PS on and DRV on and power supply puts out all voltages correctly. Any help greatly appreciated. TIA

Re: LG 55EC930V won't turn on
Did you notice if the backlights came on when you did the force on? can you see the menu or any text with a flashlight? -
Re: LG 55EC930V won't turn on
This is a OLED, this set doesn't have LED backlights.
Do you have a Service remote or old phone with IR sensor ?Comment

Re: LG 55EC930V won't turn on
Oh okay, my OLED had this same issue. At the end it was a panel problem.
But it doesn't mean that your tv has also faulty panel. Sometimes mainboards fails too.Comment

Hi All,
First time posting here ... my name is Kevin but my friends call me Journey.
I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again.... -
Hi all,
I've got a LG 50PK590 plasma TV which upon plugging in will click three times and the red LED in the corner will come on and stay on, the TV however doesn't come on (no humming, sound, video, etc.) and using the touch controls or the remote does nothing. On exceptionally odd occasions, the TV will come on and work normally when plugged in and will last about 5 minutes before going back to off and unresponsive.
I've got the back off of it and none of the caps stand out as visibly buggered, I've also tested the three resistors in the corner of the power board which...02-24-2025, 07:23 AM -

Hi,
First post...
I have this TV, which was working, then suddenly would not turn on. It would get the clicking relay then flash up the screen for less than a second, off for a second then on again. Removing the plug the relay continues to click on and off for a few cycles, which I don't think it did before.
Left it a few months, then finally got round to taking the back off, and it worked as it should. So I tested various bits and all was well. Then turned it on again, and back to the clicking relay.
I disconnected the main board from the power... -
A) TV initially dead
B) On a hunch of a locked up Google OS, plugged in a USB memory stick with latest FW and plugged it in. It booted into the update screen, completed the update and restarted to Home screen.
C) Was able to perform a Reset from Settings menu and completed out of box configuration.
D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical...
