It worked about ten minutes ago. (sat. April 4th, 5:45 CST.) Then bookmark the link, or print out the topic.
If you use a good magnifying glass you may be able to see the cracks in the soldering around the pins on the circuit board. I fed in a small amount of new solder, with rosin flux. All gauges have worked perfect since then. Plus I have done the same repair to Neons belonging to family friends. The last time I did it, I think it took 20 mnutes.)
