Have TV Questions? Ask a TV Technician
What's the make and model number of the TV?
Do you have another source (like a DVD player) connected to the set, and if so, does it have this problem also?
Did this just show up one day all of a sudden?
Let me know!
It just started happening about two weeks ago, and was out of the blue. This make has a built in DVR, so I dont know if that could be part of it or not. We never use the DVR.
But you say the picture eventually will come on, but only last 15 minutes or so, then it goes dark?
When it goes dark, if you press the MENU button on the TV, can you get the LG's menu to come on screen?
When this happens, do you still get sound? Can you turn the volume up and down and turn the set on and off with the remote?
No nothing, just the colors. When I try to turn it off their is a delay, but then it shuts off.
Then my guess is that you have a defective Digital Main PC board.
Do you have any electronics experience and would feel comfortable trying to replace this, or would you be calling a tech?
The price of a DM board is usually in the $350 range, maybe a bit less, and if you have a tech come to your place to installit, that would probably be another $170, depending on where you are.
