I have been working on the same thing. I have got to the same point, I seem to be allmost getting s-video, but the output from my c64 has colour bleed on some images but the s-video output from my pc dosen't look too bad. I coulden't realy tell if there was any bleed over.
As for the ICs, its the LTS5QTB which is responsible for controlling the AN2526NFH via the IC2 bus. It is also responsible for generating the volume and brightnes OSD sliders and it is supposedly fed by a 2402W IC2 serial EEPROM.
I have not found a datasheet for the LTS, but from what I have seen in the internet here
the chip had hidden menus, but the author of the document dosen't know how to makethem appear 'normally'. Sadly he has yet to return my email on this matter.
On the PCB for my LCD there seem to be access points for the IC2 bus next to the EEPROM, suggesting that it could be in system programmed. The site which hosts the text file mentioned above also seems to have a binary image if the EEPROM's contents. Viewing the file in a hex editor shows that little of the small EEPROM is used. I cant see it being too big a task editing the image byte by byte until we get the desired result. Anybody know of a DIY IC2 programmer? :rolleyes:
Heres a screenshot of the hex editor with the EEPROM image loaded:
PS. When I get a hold of a digi camera Il take a few snaps of what I have done so far to my LCD.
