If the convergence adjustment is not moving the beam chances are theconvergence IC(s) are defective. If you know how to solder andunderstand TV safety you may be able to fix it. With power disconnectedremove the back. You should see two large heat sinks with large ICs (3by 6 inches) with about 30 leads going through the circuit board.Numbers on the ICs should usually be something like STKxxx-xxx or somevariation with x being a number. These ICs control the position of thethree beams. If they go bad you can't adjust one or more beams. Replacethem both as you don't want to get in there again in 3 months. Cost isnot that much. http://www.tritronicsinc.com or http://www.partstore.comshould have them at a reasonable price. Before replaceing the ICs lookat the circuit board closly for cracked solder joints. Resoldering anybad joints might just solve your problems and avoid replacing the ICs.Good luck and remember safety.

    these ICs can be found in the power board itself sir.

    they are very easy to locate with a service manual. and i would suggest you to buy a service manual for better assistance and it would be safe.

Your convergence ICs or convergence board is bad. More than likely it is the convergence ICs. About a $100 fix from a reputable repair shop. Hope this helps. If you need more info let me know.

The screen is showing a ghost or double picture


Does the picture look 3d? colors out of place and or skewed?


If it does, go into the customer menu with the Sony remote and select convergence----if red or blue are warped and will not move in some direction--you have a common problem---CONVERGENCE.

Confirm model number and tell me if it is 3D like picture.

I can if it is tell you what is needed to fix it--I am here to help people and I do this here for free.

3d looking screen


If the auto convergence didnt adjust the picture back to normal, you will need a new convergence power supply board.

Bow tie looking picture with 3d color mis-alignment


you have lost convergence. First thing to check is to see if you are missing the convergence option in the customer setup menu. if you do not have this option then i suggest reading the article in the tips and tricks section entiltled "the fl231 fuse problem" this is a common and sometime easy repair if you do have it then you might need a convergence power board
