You need to replace both of the convergence chips.

The question here is if I tell you how and what is needed can you do it?

It involves getting at the chips and soldering etc. Some people can do this themselves with help, but others cannot.

I am here to help.

My rca projection tv has blue and green images like a 3D picture would without your 3D glasses, a double vision image and no other colors


sounds like the sensors are out of focus and your red sensor isnt turning on. look in the back of the tv for a master reset button or in your menu screen some sort of "Flash focus" or "convergence". They will realign the 3 sensors.

Looks like 3D Picture


You probly have a convergence cicuit failure. Replacing the convergencr IC's will probly fix it.
I recommend a professional repairman to
do it though. Particularly if it needs further adjustments after the IC's are replaced.

53UDX10B 53 in. Rear Projection "3D vision"


the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck
