LG 29FS4RL
Turns on works, when turned off using the control, it only turns back on with great insistence. Cause: zd827 shorted, replace or remove it and the TV works normally again Eletrônica Santista
LG 32LP360
When plugging into the socket, the red LED flashes twice and no longer lights up, only to light up again after removing it and putting it back into the socket. Two LEDs on the bars burned out, causing the power supply to go into protection. In this case I replaced all the LEDs on the bars, even the ones that were still working, in a technical case I don't just have the original LEDs, changing the bars for new ones also solves the problem.

Without image, sometimes with slow image and sound (thick voice, out of frequency) then everything freezes. The xtal x201 glue damages the components around it, harming the oscillator. Replace the replaced components l206, x201, c298, c299, r205, r208, c269 and r211. I hope I helped! Julian C Braga

TV restarts, works fine for a while, turns off and turns on again The problem arises due to problems connecting the voltage between the power supply and the MB or the TV detects a failure at 3.5v_st. The problem is normally in the connection cable between the power supply and the board, check the connectors, fix the cable with "glue" or another means. Constantino Palha
