Facing TV Problems? Ask a TV Technician.
Hello and sorry you're having problems.
Offhand this can be caused by one of several things. In order to determine what, I need to ask for more info.
1) How long have you owned the set for and when did the problem occur?
2) What sources are connected to the TV (cable/SAT box. DVD, etc.) and is the image dark regardless of what source you're viewing from?
3) How dark is the picture- is it barely visible?
Let me know when you're able to see my reply please.
