CombustionMark:
1. no, when I turn the express on the leds do not do a cycle test,
2. No I haven't but at this point I'm pretty confident it's some form of soldering problem.
Also I have tested 2 different display drivers so I don't think that's the problem.
RJ, my soldering iron does not have an adjustable temp, but I will whip it down with alcohol and see what happens.
Also is there any particular place that I should start to touch up the joints or do I just need to go in and resolder everything?
Thanks
