working out pinouts
i just got a lot of 7" screens off ebay cheap, however they came with no adapter cables. From the looks of things they accept a composite input but i cant find any pinouts or information about them online.
The board on the screens says hs-vha702d-main , sam-0346-03 and jo1363, the controller on it appears to be a winbond w78e54bp. Any information about how to figure the wiring for them would be greatly appreciated .
