Re: LG 42LD450 no picture&sound problem
I replaced all capacitors on powerboard but nothing changed.
Powerboard voltage outputs like this;
Left side values printed on pcb, right side values measured.
3,5V - 3,3V
12V - 12V
20V - 21V
I noticed that when turn on tv and measure voltage from logicboard to T-con, multimeter shows 0V.

LG 42LD450 no picture&sound problem
Hi,
I have 42ld450 Lcd TV. Picture and sound goes off when watching. I powered off and on but red light blinling continuously without backlight, picture, sound.
I checked voltages from PSU and there is no problem about voltages.
There is a switch on logic board and when press it backlights turn on for a second and goes off. I think backlights working well.
Do you have any idea? -
Re: LG 42ld450 blinking red light
I have 42ld450 with red blinking issue. When I was watching TV suddenly sound and picture went off. I turn off/on Tv but red light blinking continuously. There is no backlight, no picture or sound. I checked DC voltage output from powerboard, all seems ok. There is a switch on logic board, when I press it, backlights turn on for an half second then goes off. Do you have any idea?Leave a comment:
