Greetings group. I have a Samsung ctv model CB-677Z . Randomly the screen turns slightly green.
I suspect it may have a heater to cathode short.
I have had 2 other tv's with a similar problem, but both of them turned the screen almost fully one colour. I fixed them by making a new heater winding on the LOPT.
In the EFIL cd, for Samsung tv's I am told to connect one end of the new heater to the video supply rail via a 1Meg resistor.
I am not certain what the video supply rail is.
Can someone please assist?
Thanks, Russell.
