Question about Sony KP-48S75 48" Rear Projection Television

1 Answer

Sony KP-46v25 rear projection: picture width contracted 4-5 inches on left and right.

Picture OK towards center 70% of screen. For the first several days, turning the set on an off several times would eventually correct the problem. Now the problem is apparently permanent and seems to be getting worse (dark bands on left and right are widening). I have a jpeg that if anyone is interested. Also, I have schematics for this set.

Have you measured the b+ yet? I would like to see the schematic. It could be the b+ section or the horizontal drive circuit.

Bad picture

Are the convergence controls also out of adjustment? Please respond to this same post and I will help you. If you could post a picture of what the screen looks like that would even be better.

You need to have the convergence IC's replaced. A repair like this should run you about 300 bucks or so. In most places.

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.
