It appears that you may have a green drive issue. Try adjusting the Sreen Control it is located in the front of TV.
1) Remove Speaker Grill (it just pulls off) start at one end, 2) Remove cover (5-6 screws), 3) Adjust control. The control is located on lower right side towards bottom. A small black device with 2 rolls of controls, adjust the center control on bottom row counter clock wise, until you get a black and white picture.(adjust with color control to min).
If this does not work you light bulb (CRT) is bad about a $750.00 repair.

Sounds like the convergence amp are heating up and going out. you can look for the amps and see if there is a loose connection on the trace and if you can solder you may be able to save them or just replace amps with orginal. This is sometimes caused by moving set around, Set being so heavy it can not take a joult like the direct view sets
According to several sites, the problem is with the convergence via the
voltage on the color ray gun tubes that get out of adjustment. They are
also known as retrace lines
Sony wanted between $150-$300 to diagnose and fix -- instead I was able to complete this repair in less than 15 minutes! Since I had been through the
routine once more and I was sure others are running into this issue, 1. All you need to complete this guide is one flat-head screwdriver and one Phillips screwdriver as well as a delicate touch. 2.
Front shot of the television. Their are two screw holes on the front of
the unit near the edge of each side right next to the speaker grille.
Close up shot of the screw hold. It is covered by a plastic cover that
has two tabs holding it in. Carefully pry them out with your flat head
screwdriver. Do not apply too much pressure or you can break the tabs
off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.
To remove the cover, pull from the bottom of the front case and rotate
towards you. Once you rotate it out, the top will disconnect and come
loose. Do not pull it off, as there are cords attached. (see picture)
Loosen the cables attached with the twist ties and set the front cover
to the left side.
With the speaker grille and cover removed, you now need to remove the
wood panel to expose the inner electronics on your Sony HD TV. To do
this, remove the four Philips head screws from the panel. Then, pulling
from the right, rotate the panel off and the electronics will be
6. This is a picture of the inner electronics of your Sony Rear-Projection High Definition television. The little black box towards the front of the unit is where we will concentrate our time as it is the control for the voltage & convergence adjustment.
When focused in on the controls, you want to concentrate on the bottom
row for the voltage / ray gun projection adjustment. The colors are
labeled below and from left to right are blue, green, and red. Choose
the one that needs to be adjusted and turn ever so slightly with your
Philips screwdriver to remove the lines. In my case, the red just
needed to be turned 1/8 of a rotation to be back in adjustment. Do not
turn to quickly or abruptly or you could possibly damage your TV by
varying the voltage too quickly. I hope this guide worked for you?
