Question about Projection Televisions

1 Answer

I have a Toshiba Projection Television Model 42H83. I have had it for 4 years and it always had a magnificent picture until yesterday. Now it has a red ghost to the right of everything. I tried adjusting the convergence but it wot let me move the RED line far enough to the left. When I go to the eight patterns I have a red Cross a distance away from the one I am supposed to line up with. About 1/8 of an inch to the right.

If the board was "repaired" the settings should not have changed. There is a particular order to performing a convergence alignment. Do a web search for the service manual that will document the specific steps you need to take. Search using the model number and the keyword "manual". It should be availabel for $10-$15.
