Turn the color all the way down on the TV. You
should get a perfect B&W picture from dark to light
& at any brightness or contrast setting. If you dont
it needs grey scale adjustment & odds are the CRT
is showing its age. If CRT weak you have to compromise on
things for best pix. Somewhere there is a thread I put up
on doing grey scale on a similar aged RCA. I will see if I
can find it later.
The Sony may have AKB "automatic kine bias" if so there
are no adjustments. Nothing easy you can do, but if
its the CRT the pix will start flashing on & off especially
when cold.
