Unplug the TV from the ac wall outlet for about 4 minutes then plug it back in and turn it on. If it still has a double image then tell me if it's affecting the menu screen from the TV (not the cable menu). And is the double image in red and blue?

It sounds like a convergence problem. A fairly common reason for thisproblem is the convergence chips have failed. They are usually referredto as "STK" chips since the model number of these chips start with STK.I will put a link to another part of this site where someone has postedpictures and a link where to get the parts should you decide to fix ityourself. Look at Ecullier2012's posting. Jean's posted site will notfix this problem. Hope this helps you out. Let me know.

If you have a CONVERGENCE problem and it will not adjust---the two STK-392-150 Chips this set uses need to both be replaced and the set adjusted with the original remote control.
You can, if you are able to do the repair, buy a pair of chips for less than 14 dollars plus shipping on Ebay.
If you cannot do the repair--shop around your area--most shops are going to charge 300 or more for this kind of repair.
When you consider the cost of the parts--if you can do it or know someone who can--you can save the set and a lot of money--This repair can easily be done right in your home in about 1 hour--I know as I have done hundreds of them---did two today.
The chips (with the back off of the set) should be on two metal heat sinks on the board on the far left---they will be facing the front of the set.
All that is required to get at them is to remove all the plugs on that board and the screws that hold it in and tilt it up so the bottom of the board is in view---you unsolder both chips (about 18 pins each) and remove the 2 screws that hold each to a heat sink.
With 2 new chips you put heat sink compound on the back of each--it is a white grease to move heat quickly from the chip to the metal, and solder both chips in----put the board back down and all the plugs back(I usually mark all of them so I know where they go) and turn the set on and see what you have...
Most of the time this repairs the set--go into the customer menu and adjust the convergence and you are ready for another 5-8 years of life---this is the normal lifespan of these chips.

SOURCE: projection sony tv is yellow
Most likely it is the Optical Block. It has been a issue for most of the Sony LCD Rear Projections manufactured over the last 6 plus years. Your Model may still Qualify as a factory recall. What you need to do is to get in touch with Sony's Customer Service at 1800-222-SONY and see if it does Qualify.
If not, it is a expensive repair costing 1200.00 to a 1500.00.
I hope it still does Qualify for a recall,
