Problem seems in convergence out section.

TV needs Convergence Out ICs replacement.

If you have TV repair experience and know good soldering work then you can give it try OR get help of qualified TV tech to fix it.

If you need further help, let me know.

Red and Green have separated in double image and there is a dip at the top. Please Help.


You have a defective CONVERGENCE IC. Most TV use 2 identical STK IC & both has to be replaced at the same time. If you are not a technician I don't recommend doing it yourself. There is a lot of desoldering to remove the chips with 16 or more pins- and soldering the new ones.
Good luck! Astrotech

Double image/ out of focus with green and blue seperation


Your tv is crt-based and is out of convergence. In other words, the settings for keeping the Red, Green and Blue images aligned have drifted and must be reset. This is common with CRT projectors and CRT rear projection tvs.

Refer to your owners manual for instructions on re-aligning it.
