Sounds like a problem in the blue HV convergence circuit, bad yoke or IC chip that drives the yoke coils.Could also be a bad blue CRT. Look at IC901, STK392-110 and releated components in the circuit, page 97 of service manual.

I would say that your Projection light is busted, I'd recommend that you take it back if you have a warranty, if not then find the appropriate part by googling a company that can service those parts for you.

Colors are skewed on Pioneer Pro-520HD


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.

Picture has blue,green,and red phantom lines on the screen


Sounds like a convergence problem. Are you interested in fixing this yourself? If so you will need to know how to solder well and use a meter. I can assist you as much as you need through the process. If you post a picture of what the screen looks like we can know for sure what you have going on. If you call a repairman to fix it he will charge somewhere between $300-$500 to do the repair. Let me know if you need more help!
