It sounds as if the color controller/circuit board is becoming sensitive and may soon disconnect. Don't be surprised if someday soon, the picture goes very dark or vanishes completely. Have a technician check it out with his test equipment to locate the exact problem.

SOURCE: Hi there My Sansui TV screen

It is an indication that you have a problem on the vertical section on the main board. The faulty parts is the electrolytic capacitor which affect the linearity of the screen that's why you encountered that kind of problem.
I've advice you to send it to repair shop or look for a qualified technician to isolate the faulty electrolytic capacitor and do re-soldering for some dry joints on the main board.Once replaced the capacitor your unit will back to normal again.
thanks for using fixya...
