Re: LG Plasma 60PB6650 Screen Flashes, No Display, Good Voltages

Sorry to bring up an old post, but I just had the exact same thing. I followed this thread and decided I needed a new main board. I ordered a new main board from a supplier and installed it, now the TV does come on, but sometimes get stuck on the boot screen, and sometimes after about 2-3 minutes will go to the HDMI input. Sometimes buttons on the remote respond in about 10 seconds, and sometimes not at all. I have not attached a device to see if picture will play until I resolved this issue. I was thinking something...

Re: I have a LG 60" plasma model 60PB6650-UA

I know it's a little late on this thread, but you guys really helped me out!! I did the test pattern by jumping the pads, and the tv comes on, does red, green, blue, then swipes all ways with white.. So I am going to guess it's my main board, but was also thinking could it be the logic board? Just curious if someone will answer, I think it's the main board, but not 100%..ANY help will be greatly appreciated!
