I have an LG50PK750 that about 6 months ago started not turning on when I hit the power button. The red light on the front would turn blue and after a few seconds it would go out but the screen stayed blank. If I waited about 10 seconds and turned it off and then back on it would come on. Over the months it would take 3 or 4 tries before it came on. after a while I decided to just leave it on, and when I was done watching it, I would let the firestick plugged into it go to sleep. This worked fine until we had a power outage. Now the screen will not come on at all. I have done some troubleshooting, and thought maybe it was the voltage converter on the main board, so i replaced it but I still get the same thing. I have check all the resistors and they are OK. All the voltages coming off the main board are where they should be both when in standby and when turned on.
Any suggestions on what I should look at next? I know the TV is 10 years old, but I'd like to get it working so that I can put it in a bedroom. Thanks.
