Question about Televison & Video
I have a 52'' Mitsubishi Rear projection- there is a blue bar about 3'' tall & 18'' long at bottom left of the screen - what can it be ?
Hi. this is called convergence failure. the convergence board is a circuit board that regulates the RGB(RED BLUE GREEN) streams that make up the color picture. If the convergence board chips are malfunctioning, you will see a distorted view of these RGB streams. This is what you are experiencing at this time.
Simply replacing the convergence board or chips will fix this issue.
Please rate and have a great day:)
