Any advice on what board I should replace if the left half of the screen is no good, just showing white and black vertical bars? Right half is fine. Is the panel kaput?

DLP TV: Left half normal, vertical 6" band center is gray, right half almost black. What's wrong?


No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.
