Question about Samsung SPN4235 42 in. Plasma HDTV
For the past year or so for no reason the picture goes black but sound is there, not noise, you can turn the volume up or down, and all other functions work fine. I learned early on that a gentle tap to the upper right corner of the back cover brings the picture back. there is no telling when it will happen again. it could be 4 time in a day and nothing in two weeks. is there a loose connection or cracked board. why tapping helps? is it due to get worse?
It is a loose connection, need to open the unit and the tap on the board and cables connected to check the loose connection. be careful to use a rubber gloves.
