I have a 60 inch Mitsubishi and there are light red shadows in the tv. is this an easy fix

It sounds like you need to re-adjust your convergence. The purpose of adjusting your convergence is to align your red, green, and blue colors. Moving your TV often causes this problem. I hope you get it going.

Sony kdf-e50a12u rear projection lcd bravia. red shadows

This is due to you having a projection tv, some projection tvs are really bad for game playing and especially if you have a hdtv. even in the p23 manual it says that you shouldnt use with a projection tv cause it can damage your tv's screen permanently. I personally still play mine but, thats likly the problem.

The screen seems to have two of the same image, green and red.

The fix is to replace the two Convergence IC's( STK392-110's) with STK392-150's. They are located to the right side of the chassis and mounted to large heat sinks. Be also on the look out for some burnt resisters and or discolored resistors that failed becuase of the IC's failing. These would be located just to the left of the heat sinks. If they are burnt or severly discolored, you will need to replace them with the exact valued resistors. In this high current circuit it is a must.
I hope this helps,
