Hello. I have a LCD TV LG 42LD751 sitting in my storage room for a year now. Now I get a smaller version 32 inch with exactly same simptoms. So with two of them I need your help guys.
With power on LED blinks slowly and it can blink indefinitly ( left it over night) Electrolyts are good.
All voltages are present on powerboard. PSON is 3,3V, 3,3V present, 5V present, 12V present and 24V present. Only 24V is litle higher than 20V. I suspect that something on 24V rail is at fault that inverter could not come on. I've searched this forum for similar faults and only find one post that mainboard could be at fault. Is that possible even if the PSON comes on?
Best regards
Danilo
