Please help me identify these two chips on a D2-438101-2 video board: ETCCY6BA0220ODD & ETCCY6BA0220EVN. I think they are controlling the TV output format.They are probably EPROM*'s. The first one (ending in ODD) contains the odd bytes of the program and the second one (ending in EVN) contains the even bytes of the program.
It's a 68 pin quad flatpack marked with the following:A few small items w.r.t. 'chip-determination':
9535 . W32060
A crude guess is that it's a microcontroller or some kind of programmable gate array chip.
Any clues on the origin and function of this chip would be very much appreciated.
