Datasheet PDF for the SF064VT2 part, VGA edition, roughly 222 KB. The VGA suffix most likely marks the document section or variant dealing with the video interface, while separate INV and ADV files exist for the same base number. A technician would use it to check input signal pinout, sync and timing requirements, and supply levels when a display shows no image. Confirm the model and revision on the unit label match SF064VT2 before relying on pin numbers, since the VT1 version has its own documents.
