Question about Televison & Video
The red on the convergence adjustment screen will not adjust properly. When the tv is turn off the on again it will change position on the convergence adjustment screen
Dust will not be a issue with convergence.
Not knowing brand and model and if adjustments were "saved" you could also have a problem in the convergence circuit--chips or other parts.
Brand and model are needed first.

One of your convergence IC's has either cracked loose or burned out. The IC will have to be resoldered or replaced and then the convergence circuits realigned. If you do not have experience in repairing convergence circuits then have a qualified tech handle it for you. This is by far the most common failure in the projection sets and a good tech can have it fixed in about an hour and a half. I charge $150 for that but shops in your area will vary, so call around.
