Have finishes building the 6 I bought in first coop. 4 of six power up and run first tests fine. I board has 3 and 5 volt leds lit up fine but does not do self test. the other board has power and does self test but it is real slow and I have one channel led lit up??? Where do I start???
Hi tombmatt,
For the one that's really slow, as egenoup says, some of the PICs from the v5 coop had bad firmware. I ran into the same problem & wrote about it in this topic: You are not allowed to view links.
Register or
Login. So you'll need to reprogram the PIC (or get someone else to do it for you). Where are you located? Maybe there's someone nearby who can reprogram it for you.
As to the one that doesn't do the self-test, the first thing to do is to check that all the chips are installed properly (in the right direction, fully inserted in the sockets, no pins bent under them, etc). Next, carefully inspect your solder joints looking for solder bridges or bad solder connections. If you don't see anything obvious, the next step is to take some good photos & post them here, so others can take a look & see if they can see anything wrong.
Let us know what you find & we'll try to help however we can.
Good luck,
Dave
