Or, maybe even a ribbon cable causing an issue, cracked ribbon, damaged connector, ribbon not seated in its connector well. Reminds me of those old CD-ROM drives where the tray closes as soon as you open it, maybe research those to get an idea as well.I also had a Pioneer touch screen with a bad ribbon, I think it stopped it from opening correctly and or displaying things, at any rate, the ribbon can cause problems in the motorized screens. The Pioneer was not a flip out screen, but the face was motorized to drop down to put a disc in or SD card or whatever. And actually the ribbon wasn't bad in it if I recall, the connector the ribbon plugged into broke and it didn't have enough pressure to make contact, so had to bodge it a bit to make it make contact again.Since you had it disassembled, maybe make sure any ribbon cables, especially those going to the screen are seated well and or not damaged or gotten pinched, they can be very fragile and easily damaged, even if they look okay. edit: and they just flat out go bad sometimes from flexing / open and closing it over time.Could be a bad component causing it it to malfunction, which could make troubleshooting near impossible, really hard to say at this point. Also make sure your small SLA battery is fully charged to be certain the voltage isn't dropping too low causing the head unit to behave weirdly when trying to open its screen.  Unlikely, but something to rule out. Perhaps test all the buttons to see if any seems stuck, that can cause wired problems sometimes too.Other than that you may just have to tinker with it and hope for the best.</blockquote>
