I have an old car DVD player sitting around that has a fairly decent secondary TFT LCD screen (hannstar 721h440b19-a1) that I thought I could use with my Raspberry Pi 3 Model B.
I opened up the unit, and the issue I'm running into is that the control board receives the video, power and audio signal all through a single USB connection. I was curious if there was a simple way to get the display to work with my raspberry pi with the least amount of hacking to the control board. Is there a way to pass video through USB on the Pi? Or could I desolder the USB connection and run wiring for power, video, and audio separately?
