I’m having a little trouble too with the 12.1 upgrade as well and have hit a bit of a wall. I’ve been having a great time (and learning LOT) modding my Picade thanks to everyone here (so tremendous thanks to xartle, Luis, Dyltone, Paulcheffus, and everyone else!).
I ordered the LTN121XL01-N03 from displaysscreen.com and the control board from EBay. The screen failed to respond with the first control board, so I ordered a second to validate - with the same result. The control board LEDs light up green, turn red when I toggle power, etc., but all I get from the panel is the inky blackness of space and the stench of death (imagined). I’m guessing DOA. While the EBay seller is incredibly responsive, displaysscreen.com is not so much - I’ve sent them a couple of notes requesting RMA and have not heard back in several days.
I’m hesitant to throw good money after bad and blindly buy another panel from displaysscreen, but the Picade is so great, it almost requires this mod. So I find myself searching for the white whale - a 12.1” LED-backlit XGA LCD with an HDMI controller board included. This is as close as I’ve gotten:
What do you guys think about this panel?
The obvious disadvantage is that the display+side brackets width is listed at 279mm (so nearly 11”), and we only have 10.5” inside the cab to work with. I’m thinking that’s nothing that a Dremel couldn’t fix (or alternately - extra cuts in the sides of the cab which would be last-resort). The seller happens be the reliable EBay provider that I believe a lot of us here have used, so bonus points there.
