I have an old NTCS C64 that I converted to a PAL, by switching the crystal to a 17.734472Mhz and the VIC chip.
Board is 326298-01, 5-pin, rev A.
VIC is 6569 R5.
I saw the P2417H listed as working smoothly at http://wiki.icomp.de/wiki/Chameleon_Monitors
So I went and procured a P2417H in order to get Vic-II sync, but it seems whenever I enable that the screen goes black.
I can run several resolutions at 50hz (though the monitor says the native res is 1080p60).
I'm using the VGA out directly from the TC64.
Is there something I need to configure? or have I broken my C64?
