Title: Problem with Express
Post by: shgshgshgshg on July 22, 2012,

Hey everyone,
I'm having some problems with one of my expresses. At first glance It appears to be the same issue as in the other thread I posted about earlier (http://diylightanimation.com/index.php?topic=8833.0).
I have just checked the 2700PF and it is not touching the PCB. I have also checked the voltage against pins 27 and 28 on the PIC and it appears to be about 7 volts. My understanding is that this should be about 3.3.

Other info:
3.3 and 5v lights are both on. All of the chips look correct. Channel 16 light comes on when I press the select button...

Thanks,
Stephen G.

More info:
 I attempted to put a working pic in the broken express and it did not have any change. I put the PIC from the broken express in a working express and it did not work. So I know the PIC needs to be re-flashed.
Also with no PIC in place on the broken express it is only showing the 3.3 volt light not the 5 volt light.

With a bright light and a good magnifying glass, I would check every soldering joint
