Tri coloured ghosting

I have been given an LG Rear Proj TV model PT53a83t The right side of the image is sharp and clean but the left side has a ghost less than 1/4 inch wide of red/yelly/blue. Would this be fixed by auto colour aligning as per the user manual

My LG rear projection TV RE40NZ60RB colour is ghosting with three colours separating. Colour converging does not rectify

There is a problem with the convergence circuit. It can be as simple as poor solder connections at the pins of the convergence IC or a defective IC. If you can solder, you can fix this yourself. Please confirm the model number of hte set and I'll provide the part numbers etc. required to resolve this.

Red Ghost

This may be a convergence issue but it is difficult to determine with that description. Watch this video and see if it will help you determine if you have a convergence problem or possible something else.

Half the screen has ghost image (not focused)

Replace the convergence ICs. They are located on a large aluminum heat sink with STK numbers stamped on them. They cost about 10.00 each. They have to be soldered in. Let me know if you need anything further.

Ghost images

Sounds like a light engine issue to me. Is there anyway you can post a picture of the issue itself?
