T112 screen doesn’t power up – touch screen works

[Rod]

I took apart my T112 to put a new rotary knob in. When I got it all put back together and powered it up, the screen didn’t come on at all. Not a white screen, just nothing. It worked perfectly before.

I connected an external monitor, which works. The touch screen on the T112 does work, there’s just no picture. It’s a pain to try to poke around accurately while looking at a different monitor but it’s manageable.

What did I do? Absolutely everything is reconnected.

I tried plugging the display into the external monitor jack, but it’s a different plug with fewer pins.
