Sears Electronics-Model 774 15280
color flucuates-sometimes normal , sometimes with green corner and often all pinks and greens-
can this be fixed?? only 5 years old!
Help please.
It sounds like the De-gauss circuit isnt working. It demagnetizes the TV tube.
It's something only a tech can fix though.
This sounds like your convergence correction amplifiers have malfunctioned. These Integrated Circuits often burn out after a few years (STK392-110) they can be replaced with a higher version (STK392-150) However it is important to have the biasing circuitry checked to make sure nothing has burnt out as a result of the ICs malfunctioning. If you have a background in electronics you can repair this problem with very little effort, however if you do not have a background in electronics, I would suggest that you have your TV serviced by a qualified TV technician.
I hope this helps,
Thank you,
