It is normal for a rear projection TV or monitor to slowly drift slightly out of convergence as the CRTs age. If any sudden drastic change has happened then there has been a component failure on the convergence board. Usually it's the large ICs and maybe some caps and low wattage resistors as well. Could be any of many things. A professional service person has the equipment and know how to check for bad parts, and usualy also some spare parts lying around to replace and check for change. Most common fix is replacing some of the STK chips, which aren't very expensive, but it could be the convergence board itself, or the CRT fluid. In short, kicking it wont help, playing with the menus either. This is going to cost you... consult a Repair person and get an estimate for the repair. Good luck

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

RCA 52 in HDTV red, green and blue colors not alligned - concave

That repair only repairs the issue of the convergence option missing from the on screen menu. If thats what your problem is then the ITC222A convergence option missing repair kit at the following link should repair the issue. The kit contains the fl231, DL231, CL230 and the CD with detailed instructions.

The red blue and green lines are at the top of the screen, the colors are out of focus and the picture seems concave. the menu has a convergence label,but it does not appear on the screen

The supply for the convergance circuitry is off the flyback (high voltage) transformer. There are three fuses to the direct right of the transformer. One of these is probably open. Also re-solder or replace the rectifier diode off the blown fuse. This should solve your problem.

Rca p56927 colors out of line

This is a convergence oroblem. First question is do you have the convergence option in under setup in the customer main menu?... if you dont you may have the very common fl231 fuse problem; i have wrote a article on this under the tips and tricks section. this is a very simple inexpesive repair. If you do have the "convergence option" then you may have to replace one of three cuircit boards

Screen lookes like colores separating

This is what is known as convergence. a projection tube ussally has three picture tubes.. red green blue. they all have to align. the concave picture indicates complete loss of convergence or convegence power supply. First question on these sets Do you have the convergence option in the customer menu under setup. if you do not this is a indication of the common "FL231 fuse problem" and inexpensive simple repair. I have wrote and artilcle on this under my tips and trick section. If you do have the option then next does autoconvergence work. in you case i would not think it work. under blue and red manual convergence does the crosshairs move. if not then this is indication of convergence power supply board. if they move at all this may indicate a convergence amplifer problem.

Red and blue colors go across the screen. picture looks concave.

Greetings joanne7,

The issue you are having could be caused by your television needing the convergence adjusted. During production your televison has the three picture tubes that are converged to form a single image on the screen. Over time these can come out of adjustment.
If you go to this link http://download.jazel.net/misc/filecache/b8/b89bca4c8b740315d378e8ed030461c5_1227-517SeriesOwnersGuide.pdf and check pages 57 and 58, it gives you a very detailed guide on adjusting your convergence. I am aware this model number is slightly different than yours, but I own a 47" Mitsubishi and this is the exact procedure we use to do our convergence so I am confident it is fairly universal.

I hope this helps!

This is what is known as convergence..(very common)... first question DO you have the "CONVERGENcE" option in your setup menu?.... if you dont there may be a special fuse issue... if not then more than likely it is what is known as convergence power supply issue. you have complete loss of convergence?
