Hi Guys, this 35" RCA has a strange problem, set comes on with widely spaced
retraces lines that will not
adjust out with the screen control, I`m hoping this is Q2906 (which I`m
ordering today) but the voltages on it
were real close so it may not be the problem, the wierd problem is at
channel change or turn off the screen gets bright red, I swapped the blue
and red driver transistors on the crt board with no change, checked tube on
Sencore CR 70, reads ok, Any ideas ? tia, Larry E
