I have a similar issue on a different model. After doing much research in the last 24 hours, and finding out a family member had the exact same thing happen, I called a local repair shop to get prices. The guy on the phone knew exactly what the problem was...the 2 Convergence ICs need to be replaced as everyone is stating.

Just in case anyone else is looking for this info...which is why I called the repair shop...the parts are $30 each (need 2), and the labor is $380 if you go the repair shop route. I've seen some other posts of people making this repair them selves...I'm handy...but not that handy. So, for me, the issue is will $500 get me several more years out of my set, or is it better to put that $500 into a new set.

ALL 3 COLORS ARE SEPERATED AND CONVERGANCE DOES NOT FIX


We fixed this same problem as a dyi project. Check out www.tvrepairkits.com. The kit itself come with the proper chips, fuses, and very detailed instructions which includes pictures. They also have online help if you have questions. If you know how to solder and are a very careful person, this is something that you can fix yourself.

My Sony Projection TV middle of the screen curves down on top and curves up on bottom. Picture looks dubble like 3D, screen looks like concaved. Left side of the screen color is light green and blue, right...


This is a very common failure on Projection sets. Its called a convergence problem.
You may have one or more of the following symptoms.
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
No Audio / No Video - Makes Chirping Sounds
You can see some examples and find a fix here...

Red and Blue seperate and picture curved toward the middle


You have a hardware problem, you cannot fix it using the menu. in fact you could make it worse.

Try googling DIY convergence repair if you can solder.

If not then call in a pro, about $300

Your tv has a convergance failure. the convergance ic's need to be replaced. Upgraded part # STK392-150 or STK392-160. Both ic's should be replaced to prevent future failure of other colors.
