In my case, it turned out to be that I'd damaged the trace from
pin 14 on the LCD to pin 8 of JP304.
Fixed it and the display came on. :-)
There are still long delays from when I apply power to the QMX,
to when it's ready to accept pressing the volume button. Then,
once I press that, there's a long delay before the LCD lights up.
Is that normal?
If I break power, momentarily, it turns off. But when I power on,
it responds right away.
Is that normal behavior?
Also, if I long press for power off, that shows in the display,
but the LCD never turns off and the current doesn't go down. With
the Shutdown Message showing, I can change modes and band. Looks
like it's not really turning off.
Is that currently normal behavior?
Inquiring minds want to know! (Version 9 firmware)
(Not complaining, just want to make sure I've got nothing left to
troubleshoot!)

Paul, I had a similar issue, which turned out to be pin 3 of the
display board making contact with the inductor on the power supply
board above it. /g/QRPLabs/message/107812
