This may be a convergence issue but it is difficult to determine with that description. Watch this video and see if it will help you determine if you have a convergence problem or possible something else.

The same problem just happened to mine a few minutes ago. The red image on top and bottom of the TV were way off their positions. Doubled-red images can be seen on top and bottom of the screen. Can any one help?

It could be that there is a speaker close by. It produces a change of colour.

Toshiba 57h81 green will not focus


Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

Convergence -manual


Replace the convergence amps and test and replace any or all of the 2.2ohm resistors in the yoke return path out in front of the amps. This unit takes two STK392-110 Sanyo originals, DO NOT GET CHINESE KNOCK-OFFS... Buy them from Acme sales out of Florida and you can be assured they're originals.

Red is out of convergence


These sets use STK392-110 voltage amplifiers in the convergence circuit. Chances are good that these are causing your problem. It is best to upgrade these to STK392-150. There may also be some low tolerance resistors that have gone off value. I do not suggest, however, that you do this work yourself unless you have some electronics training. Find yourself a good technician that does component level repair and not board level. The labor will be higher, but the parts will be significantly lower.

Blue ghost


If you have the ability to work on solid state electronics and know how these circuits work, you will need to replace the convergence IC's in this TV set. If you do not, call in a pro to assist you in this repair. Good Luck
