Re: LG 42PC3D - Will Not Turn On (Standby Only)

Guess who has a working TV!!!!! lol I switched out the main board and it fired right up. One thing that I noticed is that the main board has a green light on it, as well as, S/PDIF light. Those wouldn't light up on the bad board...well, the S/PDIF would light up momentarily. I am so happy...I fixed my TV for $43!!!

Thanks again for everyone's help!

Ok, I got home and checked out that cap and you are right, it has bulged. You have a really good eye! So do you think it's not the main board and the power supply or most likely, both boards?

I think I'm just going to take a chance and buy a main board. It seems to be the logical guess, lol, considering I lost the HDMI port on the DVR.

1. Power Supply



2. Main Board 1



3. Main Board 2



4. TV Overall

The other day, we had a big thunderstorm roll through. During that, I had the TV on. I saw some lightning strike close to the house. I thought the power went off because I didnt hear the TV anymore. I go look and the standby light is on. I press the power button and the LED goes to green, blinks 3 times, and then back to standby. When I unplug/plug, I can hear the relay click though.

I hooked up another TV and found that the HDMI port was bad on my DVR after all of this. The cable was fine.

I removed the back panel of the TV, checked for any visual signs of damage;...
