All voltages seem to be good. I checked all the pins on the chip with a small pick and magnifying glass and they seem to be soldered down. Maybe I have something soldered wrong.
Thanks
Here are the links, the pics are about 200k so you can see my great soldering skills up close. I can upload better shots if needed. ImageShack - Hosting :: img1100rqd2.jpgImageShack - Hosting :: img1101rtv4.jpg |
Well, you don't need C31, but that can't be causing the problem. I can't see anything else from here, but the pins on the PCM look a bit suspect, maybe.
One way I check mine and it seems to work OK - put one probe of your DMM on the PCM pin as it exists the chip - away from the solder joint. Then follow the trace that pin is supposed to be soldered to, and put the other probe at the end of that trace and see if you get continuity. Check it with the adjacent pins on either side and see what you get, too. If resistance is not zero, but not super-high, either - that pin is probably OK and it's not shorted with the adjacent pins. You can check all of the pins in pretty short order once you get going.
