Re: QCX-mini LCD top row is blocks, bottom row is blank

 

jeremy, you should check for continuity between IC2 Pins 2,3,4,5,6 & 27 to LCD pins 11,12,13,14,6 & 4 respectively.? If any are missing check soldering on the LCD, IC2 socket, and pins and sockets on the connectors between the main board and the display board. Those board interconnections are where most of the soldering issues occur. Good luck ... Ron

Unsoldered /shorted ?connections, ?CPU absent, CPU wrong way round, pins folded underneath etc are all worth checking?

Have you read the troubleshooting guide on the units webpages ??
