This is a bad digital main board. Having to unplug and plug it back in is a dead giveaway for this problem. The part number for the main digital board is 3313TD3014A. Hope this helps.

Power led blinking red and green wont turn on


For LG DU-37LZ30 specifically - On the power supply board, look for IC101, an 8-pin DIP IC. There will be three smaller electrolytic capacitors near it (C107, C113 and C125) marked 47uF, 35V. I'm being lazy here, but replace all three (only one is the real culprit). What is happening is that one of these caps is charged by line voltage until the IC (power supply controller) can start running. When this capacitor gets leaky, it cannot reach the proper voltage to start the controller. I used a 47uF, 50V replacement.
I have fixed two LG sets with this same problem. The other was a 26". It's a cheap fix!

Most likely cause:
Backplane lamps, and or the backplane power supply is defective.

I don't know the particular model, but in most of these models, these parts are replacable. I suggest giving out the set to a tech who is experieced at doing this type of work. The parts would have to be ordered from the manufacture.
