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

Re: rear projection tv
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.
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.

It is called Convergence. You have three CRTs. Red, blue, Green. When they are not aligned, you will see the individual colors. See if you can do some alignment in the users menu. Look for Converge or Convergence in the menu. Either under video or setup.
Your Convergence ICs have failed. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.
Try This: When you notice the symptons Use this simple test to verify. Go to the users menu on the tv. Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.
If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section. If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.
If you can move both in each direction then the problem is something else.
Note if one STK chip fails, you replace both regardless.
You can try to enter the menu and go to advanced setting and adjust the convergence. Push audio to go to advanced convergence and do the multipoint convergence to re-align the colors. If this doesn't solve, you may need to do a hardware repair.. all projections of this type will need a convergence IC repair sometime during their lifetime.
I have a VS-45607 and If the VS-5052 has the same menus then there are two options for convergence. One is the basic convergence where there is one set of crosshairs and you line them up. Then there should be an option for "advanced" calibration where the whole screen looks like a grid and you go to un-converged crosshairs and align the screen. Most likely not all of them will need to be adjusted, but for me, the lower right hand corner wasn't aligned right and this cleared it right up.Good luck
