I installed a bunch of these systems back in the day. They all have the failed screen. Mine included.
I have taken them apart and scoured the internet for hours researching the numbers on the back of the display without any success. I was also not ever able to find a similar screen with the same cable positioning or pin count. I thought that it was an OLED screen but I could be wrong. Early OLED screens were known to have a short life.
I never reached out to NuVo, you really would have to find a guy thats been there for a while and really wants to help out I think to get any traction but it can't hurt to try. I thought they also got bought or something happened where that was a dead end when I was really trying to solve this.
I also never tried to use one of the NuVo VSCs from the same time period on the systems, has anyone ever tried that? It has been a while since I had one opened but doesn't the board say NuVo right on it? I wonder when he said they were "custom made" did he mean even the communication protocol between head end and remote or are they the same as the NuVo platform? Are they published yet? They cant be that complex I am still surprised nobody has come up with an arduino controller on a touch LCD yet for it. Maybe they just weren't that popular, especially if it had a proprietary comm protocol. I am certain that I could decode the protocol and build an arduino interface, but the crappy iPad ap prevents me from doing so, since it exists and still lets me use my system. I am pretty sure I have a brand new VSC in a box I was saving just in case I ever needed to really reverse engineer it, but IDK if the displays fail from lack of use or from use, because they all failed even the ones that were hardly used. Once I saw them failing like crazy and we couldn't order new ones I figured I should horde one for the future.
