Re: LG 42LH50 Turns on has backlight no picture.


Sorry I meant the one you bought to get your LH50 working again (not the old broken one). Wondering where you purchased and for how much as I am not having much luck....

Shinju where did you acquire your mainboard? I've checked places online and locally and it is not easily found. your guidance would be appreciated....

Re: LG 42LH50 Turns on has backlight no picture.


Thanks for the reply. In my research it appears to be one of three things, 1) bad capacitor, 2) bad tcon board, 3) bad main board (the latter two you covered). On one site it basically said if you have no sound but backlight works (which I believe is my issue) than it is either t-con or main board which doesnt really help narrow it. I opened up my unit and capacitors appear intact, which I was hopeful was more the issue...

What range should I expect to pay for main and t-con board? What exactly is "high-dollar"...

Hi All - first time post...

Shinju I've been reading your experience with the 42LH50 and have the exact same issue. Red light before powering on, blinks, goes to solid blue but nothing - cant get to inputs or menu although the blue light will blink when i press buttons indicating that the command is acknowledged but nothing shows up on screen. Backlight is illuminated as you show in your pics as well.

Did you ever continue to mess with this or finally give up? BTW, i am a novice when it comes...
