Hi all;
This is in a real oddball CM RPTV. It has to be close to the problem, the video
is clipped black and will not drive the CRTs. The OSD shows up OK so the tubes
are good. The sub bright has an effect but not enough. The control is connected
to this IC. It appears to be an RGB processor of some sort.
Does anyone have a print for the CM A4040 ? or perhaps remember somewhere else
they may have seen this chip ? Perhaps in something for which I do have a
print. My sources for this pinout have been exhausted.
Thanx for reading and thanx in advance for anything you might have on this.
