Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

Did you replace the convergence ICs? The 4.7 ohm 1/2wwatt resistors and the pico fuses? Let me know and I will assist you, as often sonys will blow the 3.5 pico and a few of the 4.7 ohm 1/2watt resistors when the Ics fail.

Will need your model number and which manual the user manual or the service manual? Let me know I should be able to help you.

Heres how you get into the service menu. BUT be very careful write down anything that you change as this can screw your set up and if you write down everything you will be able to change it back if it affects your set. You may want to consider getting the service manual which will explain all the details on the convergence adjustments. If so let me know and I will post a link where you can get one along with free tech support to help you out with it.
