Apple II+ is connected to JVC TV. The screen looks weird. Apple II+
does process video signal correct. JVC TV may not recognize vertical
sync correctly. It looks like that vertical sync is retraced at
16,500 video cycles instead of 17,030 video cycles. It has between
15-20 frames per second.
The screen flashes each time when retrace occurs. It does roll up
very slow each few seconds. I can see blanking horizontal lines
between bottom and top of 280x192 resolution screen.
I did try to connect Apple II+ to another TV and it does work
perfectly. Do you have explanation what is the cause of JVC TV?
