Something I also discovered is that when I start in 060 mode and the screen connected to the SV.
If I then have the cable connected to the SV that is soldered to some points on the main board,
I get weird frequency on the screen. I can get 58Hz, 62,5Hz or 72,5Hz. If I disconnect this cable
from the SV I always get a stable 60Hz when booting. So it seems like the main boards Videl and
clocks provide unstable frequency. I tested to replace the 25MHz crystal but no improvement.
Could it be so bad that the Videl chip is broken?
As I said first, this is a problem that I have seen more and more of lately. So something has
been bad for some time, but now it's broken somehow.
