Question about Mitsubishi WT-42311 42" Rear Projection Television
I have a rear projection Mitsubishi and I can't get the red to converge or basically align. When I go to the advanced setup for converge the red will not move side to side just up and down. Not sure what I need to replace. The Model is a wt-a42
Have you checked your convergence correction Amplifiers? These usually go bad. I believe they are the STK392-XXX (XXX stands for the last 3 digits) Mitsubishi uses the 500 series,They should be replaced with new ones and the bias resistors need to be changed also.
I would suggest taking it to a shop to have the replacement done, but if you want to do it yourself here is a site that can help:
There are many other sites that can help you install the ICs but this one is very accurate.
If you need any help in removing and replacing the ICs let me know and I will be able to walk you through the process(be prepared to take picture to help me see what you are looking at so I can help faster.
