Thank you Alexey. That might be a good point with sync.
This computer has video switches (computer, video ...) on the front.
also, after entering _V or _C in basic, it changes the color settings.
But there is a problem especially when HitBit Art works.
After switching to the Video mode, the colors go back to blue, but when it changes to computer mode is dark blue.
the problem is that when I go back to the video mode the background is black. Of course after booting the computer it is pink again.
Also, sometimes after the reset, the image flashes slightly and is almost white, but it returns to pink (I suspec some capacitors)
If someone has a Sony HB 701, I would love to see what the picture looks like between Video mode and Computer mode.
I'm not sure what background colors should be originally especially in Video mode. (Computer mode should be blue)
