Westinghouse 47" has a black vertical line in the middle of screen


Anything from a bad connection on one of the boards (solder or plug) to a bad board (rare) to a problem inside the front display panel which is usually fatal if the issue from a cost point of view---getting any parts for a Westinghouse may also be hard as last I heard they were again out of business.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

I have a Westinghouse LCD TV that is 1.5 years old. When I turn on the TV the Westinghouse W shows up then the picture will show up for about 3 seconds then go to a black screen. The sound is normal.


I'm willing to bet it's the main board. Its the board that all the video and audio inputs. What is the model number I could find the part for you. You could change it out yourself, Its not that hard. Let me know.
