    The Reason TV will not come on now is because of the STK ICs ,these ICs not only control
    Convergence they also control Startup.One controls Startup and the other controls convergence.You must replace Both ICs.

We have a 52 inch rear projection Mitsubishi not sure of the model number and the picture is starting to go blurry with reds and greens at the bottom of the screen


Here is another similar problem with a Mitsubishi Rear Proj. TV and it has some things to try and an estimate if that is the problem.

"Cost of convergence repair is always around $400"

You could also try messing around in the menu for convergence adjustments. Usually it will let you adjust at 8 points on the screen.

Image convergence problem


Are you able to have any control over the red and blue convergence in all 4 directions? If not you need to replace the convergence ICs they cost about 10.00 each you will need two of them. A classic sign of bad Convergence ICs is a distorted picture at the top and bottom with the convergence out of alignment on at least 1 color. Let me know if you need anything further.

Mitsubishi VS-60601 60 in. Rear Projection Television Concave


You have a convergence problem my friend. Theres nothing as an alighnment or adjustment you can do unfortanatly as there are no user serviceable parts in these sets unless your a tech and know your way around a projection tv as there is alot of voltage inside these puppys when its off. But Its most likly the Main convergence driver IC's and most repair such as this require alighnment afterwords as well so the average reapir cost on a set with this problem would be about 250 to 400.00 depending on if theres any other componets that fail at the same tim?? Sorry couldnt assitya more But if you need to contact the main company at this addy CustomerCare@meus.mea.com and see if they can direct you to a reliable servicer. Good Luck
