I have a 4.3" LCD running on this driver board from BuyDisplay. I have HDMI wired directly to a component-to-HDMI converter, wired to a Wii. For a long time, it worked well, but recently, the screen responds as if there is no signal present. I have confirmed that the signal from the converter still works, and I have confirmed my wiring is absolutely correct. Before this issue occurred, the screen was going in and out, sort of flickering, while displaying the HDMI signal. So my question is this: What could have made this happen? I'm running the driver board off 3.3v from a PTH08080WAH regulator and it seems odd that the screen would no longer be able to accept a signal, but can still power on and show a "No Signal" image.
