Question about Pioneer PRO-520HD 53" Rear Projection Television
The colors on my Pro-520HD are not aligned. I have a red shadow slightly above everything on the sceen. The TV also has a blue shadow slightly below everything. This happens in both HD and SD.
You can replace your the convergence chips on the convergence board. The board is to identify because it has a large heat sink. The convergence chips normally starts with STK... After you find the chip, you can buy online (ebay has a lot of listing) and costs around $10. If you know how to solder, it is very easy to do. I just replace the convergence chips on myPRO-610HD and it works perfectly.

The convergence P.C.B. will have to be replaced. The convergence output ICs on that board have failed. Its an expensive repair, expect to spend $350-600.
