Question about Mitsubishi VS-50609 50" Rear Projection Television
You are going to need a ohm meter and they will be low value resistors--color bands denote the value and they have to be tested, do not think its possible for me to tell you which to replace as I would check them to know which.
You might find the service manual with Google for free at scribed.

You may also have a resistor burnt out for the convergence ICs.. They are all right in front of the ICs and will usually show browninsh if burnt up. If bad, replace the pair and maybe the ICs as well if they've failed again. If your new ICs fixed the lines so they'll move, then you may have problems with the centering magnets on the yokes of the crts. Dont move the yokes or magnets if you can help it, but look to see if some of the manufacturers glue broke free and let the magnet spin around the neck of the tube. If so, try to put it back where it was and then re-converge.

There are a few low value 1-watt flameproof resistors in the convergence yoke circuits. They typically range from 1 to 3 ohms. An open resistor will cause the respective color to be non-responsive. Also chack that you have the convergence yokes re-connected to the correct connectors on the board.

Projection TV sets have several common problems listed below.
Problem #1) Convergence
Problem #2 CRT Fluid has clouded over.
You can see more examples and find a fix here...

There is no "reset" as the set has in the customer and tech menus ways to attempt to manually adjust this.
under convergence in the customer menu select advanced and follow the instructions on the screen.
If Red or Blue or Green are skewed and will not adjust it means one of the two STK-394-250 CONVERGENCE chips this set uses is bad.
Depending on where you buy them they will range in price from about 12 dollars each to nearly 35 dollars each.
Let me know what you find; this may or may not be a do it yourself repair as some real expertise is required to correctly get at and replace the chips.
