Zenith was very well known for having bad pix tubes...and it was usually the green gun that was affected...there is a place in Illinois that carries the zenith line of replacement parts ... the website is www.ued.net and the name of the co. is Union Electronic Distributors....you may need to go to the website and get their ph # to talk to a rep....you will need the model no and serial no of the set to get a replacement tube...a word of caution though...pix tubes are very expensive ,,,,so dont be alarmed if it costs 500.00 or more

You need to Change out the Convergence ICs they are Big Black ICs and will have the part number on them STK392-570s I think is what they use in this model.
Mats Electronics has ICs 1-800-628-1118
You can ship the Convergence board to PTS and let them rebuilt the board 1-800-844-7871
Zenith Exchange Moduels 1-800-632-6637
If you plan on Fixing this ,then you also need to check the Low ohm resisotrs 1ohm and Capaciotrs 1000uf 35v near the STK ICs

You need a convergence repair kit - blink code 22 is almost always a convergenc issue. Sometimes it will look 3D and sometimes it will not show any video and have a 22 error code. TV Repair Kits has what you need.

This needs a special remote to get to the factory alignment screen.This is the part # for the remote ---#105-201m .
You really should call a good TV Tech on this one. They are a convergence nightmare for even a good Tech.

My red,green and blue colors are off,needs to be convergenced


HI. there is a convergence circuit board that controls the rgb stream and it also is the principal manager of the colors. if you cannot collaborate the cross hairs or, even out the rgb, this will confirm convergence board failuer. the chip set on this board is faulty. Replacing the convergence board or stk chips will fix this issue.
