Question about LG 42LP1D 42 in. LCD HDTV
Hi the problem wouldnt be the screen instead your probably right with the video card if the screen was dead it would stay black but with it changing slightly you know the screen is gettin power.
When you press the controll does an led flash on the telly to tell you the controll is working just incase the telly is stuck on an av channel.
If you have got a dvd player hooked upto the telly switch this on with the telly on and see if the telly will work using the dvd player this would rule out the fault being with the ports on the telly not picking up the signal.
If this still dont change anything then it could either be a resistor gone or a couple or it could be what you thought with the video card/controller but their is no way of knowing without testing the resistance at certain points on the board but it deffinately wouldnt be a problem with the screen so it shouldnt cost to much to repair.
It mgith be a case that the telly has overheated and blown a resistor thse can be brought for pennys but locating will be the problem let me know what you want to do and wether you are considering doing the repair yourself if you are you will need schematics to follow off and also multimeter to test resistance at certain points on the board.
