    Default LG 43UH652T Service Manual

    Hi All,

    My brother in law left this with me to try and repair (in case it was an easy job). When fired up, it has a grey screen so it appears the back light works. Nothing else comes up on screen and the remote has no other function apart from switching on and off.

    I've located the T-Con board power in (13.5v) via the power supply board but the pin layout on the board doesn't make it clear what is ground or 13.5. This should then help me narrow down if it's the power supply board or actual T-Con.

    If anyone has access to a service manual for this it would be appreciated. I've searched online but can only find the exploded view of the LCD.

    Thanks in advance,


    Bobby Slogger

    Just an update - worked out the pin and voltage allocations. power on the outs seems to be as designated. Issue appears to be main board (as first suspected). Most probably an issue with boot up. still interested in service manual if anyone finds one. Main board is same for 43, 49 and 55" models.
