Question about Panasonic PT-53WX52 53" Rear Projection Television

1 Answer

Bad red coloring

My picture appears that the red projection has been pinched. It curves up from the bottom and down from the top and the red has dominated the picture. Convergence ha done nothing to solve the problem. The only trhing that has helped at all is adjusting the slide on the red projector.

You may still have a convergence problem, but what you need to do is to make sure that all of the bias resistors have been checked. That is why I am against the old replace the STK392-110 catch all convergence repair line. However what I want you to do is actually troubleshoot this set. That will mean determining if the voltages on the convergence correction amplifiers are good, if the convergence coils are good and if the deflection yokes are good. You will need the schematic diagram to aid you with the task of troubleshooting along with a multimeter, and oscilloscope, and a signal generator. If you however do not have electronics experience, I would suggest taking the TV to a qualified TV repair shop. I know this might not be what you want to hear, but it is good advice.

I hope this helps,

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Let me know if you need any further help

This is a very common failure on Projection sets. Its called a convergence problem.
You may have one or more of the following symptoms.
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.

You have a convergence problem. Components are shorted out and must be replaced. Unless you're a technician, there's really nothing you can do at this point.
