This may be a mechanical or electronic problem that is dealing with the sync of the colour wheel. There is basicly no colour lock. This may be the replacement of the associated circuit board, or the motor assembly or the colour wheel.

The link below is describing about how DLP technology works. They are relating to a front projection type. With the rear screen type, the basic technology is very much the same for decoding the pictures from the TV signal.

if you see a purple spot on the picture screen, it may have been magnetized.

Hello im having problems with my sony wega


It sounds like you have a loss of green. This could be caused by the green gun in the picture tube opening up or the drive circuit for the green gun gone bad. Stargazer
