Hi all,
I've got this Hitachi CM2198ME monitor here with erratic flickering
and twitching in the vertical deflection, caused by some problem in the
E/W correction signal AFAICS (the parabolic signal exhibits clearly
visible erratic phase shifts). I managed to trace back this signal to a
CXA1470 IC, but lacking any datasheets, I'm stuck there. Besides, it's
deep down on the front part of the main PCB, which sticking a scope probe
in is exceedingly dangerous when the monitor is switched on.
Does anyone have this beastie on a schematic diagram, and can he/she at
least point me to some of the input signals to this chip?
Any suggestion is much appreciated.
Regards,
Richard Rasker
