7" Display Key Lock

Post by JXX_WXXXX »

I somehow managed to turn on the key lock on my 7" 1280x800 IPS display with speakers (product ID: 1667). I'm unable to access the menu or switch video inputs which is really frustrating. Does anyone know how to turn off the key lock for this display?

I just ran into the same issue. I'm guessing that reflashing the firmware might be able to reset it, but I can't seem to find the proper firmware to use.
Board seems to be: TSUX9V2.0-A
Chip seems to be: TSUMV59XU-Z1

It looks like the thing wants an infrared remote, but these units don't have the IR receiver pin connected to anything.

maybe try this?

some hannstar displays need a button press combo to lock and unlock:

Press the 「<, 「>」(or +,- ?) and the 「Menu」 buttons simultaneously to enable the Function Key Lock. When the Function Key Lock is enabled, only the Power button is active. Press the 「<, 「>」 and the 「Menu」buttons simultaneously again to unlock the function keys
