Title: LG 32LH3000 no picture 2 horz lines ? Help..
Post by: Tmg on September 10, 2013,15:39:39

Hello
I have an LG 32LH3000
seems to have no sound or picture, the backlights are lit and the screen displays 2 horz lines on the display and when warm has a vertical wide set of lines but still no images,
I suspect the main pcb but very hesitant in replacing then having to do the firmware ect and ending up with a non working set, even though its useless atm...
Any help please
Regards
TG

hi whats the part number of the main and t con boards of your set? i am sure i have just parted one of these out for parts due to a smashed screen. can you post a picture of the tv showing the fault?

The main pcb is a EAX60686904 (2)
I am now going to replace this main board and report back if this cures the fault
The Horz lines are so faint it wont show on a camera, no sound either ?
Regards.

my main was eax60686902 (0) have you tried a factory reset to see if the sound comes back?
Hold MENU on TV and MENU on remote for 5~10 seconds, then select reset option.

Hi unfortunately I am unable to select any reset option because all i see on the screen is 2 white pinstripes going across these pin stripes seem to look as if there is picture information in them even with no aerial plugged in

Hi
Do you have any sound if you connect an external input to the scarts?

Hello,
The LVDS lead has been checked both ends,
Inputting scart signals gives me exactly the same symptoms,
Currently waiting for a new main board to arrive and will report if this cures the fault
