Unhappy Toshiba TV Problem

Toshiba TV48D90

Convergence problem on Red color. Only affecting around one-quarter of the left display. The Red color on LHS shifted to the center by about 3 inches on color test.

Would this be due to convergence ICs problems? If so, how can I locate the convergence board inside the box?

Many Thanks

Pretty good bet that the convergence IC's are the problem. Another possibility is bad solder connections on the convergence control board.

Location: Suggest you pick up a service manual on the set at a very reasonable price. This will give you locations of the items and part numbers that you need. Find yours at

Good site! Secure ordering, etc. Heard a lot of good things about them.
