Re: QCX Blank LCD

Yes, I checked and reflowed the solders on both the PCB and the LCD. They seem OK.

New problem: I had 2.8 volts between the pins of the regulator until I slipped and shorted them. That let a little smoke out and now I have .3 volts so I suppose I trashed IC11!

OOOOPS!  I just noticed you have nearly 5V at the backlight, so the regulator is probably working OK.  Check the solder connection of both the connector on the PCB and on the LCD module.  All OK?
