some of these tvs have internal adjustments for everything including alignment which fixes the double image problem. if you remove the cover you will find a lot of little adjustment dials. you may find that they have symbols that show what the adjustment is for. if you want more info. email me at firstname.lastname@example.org

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.
3. 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.
4. 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.
5. 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 exposed.
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.
7. 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?
