clock not working

[therealbigjim]

I have recently assembled my Aeon clock kit from the recent coop. Nothing is lighting up or appears to work. I have 7 vdc at the plug and at points around the board but I am just guessing at this point. I have tried to attach pictures and an not having much luck. I reviewed some recent photos and I think everything is placed correctly ( but if it was it would working. ) I will try to add some photos after this post.  Jim

thank you, I was able to post the photos. I am glad some thing finally worked today. Thx. Jim

I had the same problem with mine. here is the tread on it You are not allowed to view links. Register or Login

I hope something in there helps you out

I had read that thread and compared my components and their placement. I thought I was careful when placing the led s but would that cause a no light at all?

Have you tried loading the PIC again.  From the pictures though a little hard to see it looks good.  I can not tell about the solder joints.  Try and see if that will work.  also check direction on the push button switches.  I remember reading somewhere about the direction being very important.

Are the regulators in the correct positions?

I placed the switches with the tab in the hole in the pcb. I retouched all the solder joints and have 7 vdc at all the led s and in most places on the board.  here are some more pics. still no lights   I am about to use it as a $50.00 frisbee......

mike I just posted better pics

In the great trend of second guessing oneself I removed the switches from the pcb and they were installed correctly but the switches and their socket were ruined in the process so its all a moot point now.

I have spare switches so it is not a moot point.  I do not what sockets you are talking about the switches do not have sockets on them?

When you say you have 7 volts everywhere can you test the top .1uf cap on the right side of the big chip in the middle. Should be about 3.3 volts across it. This would be a good first step.

I believe I damaged the board its self where the switches attach. From what point on the board do you want me to use as the ground for the voltage check. I have been using the top of the three soldered points  of the power connector as mt ground. from there its reading 6.1 vdc.

[n1ist]

That pin isn't ground.  For ground, use the metal tab of the 7805.  Another good place to get ground is the pad for the extra (not loaded) 0.1uF cap above the lynx's head, closest to the big number 11.

Put the probes on your meter one on each side of the capacitor I said and see if you have 3.3 v or very close.

Nothing across the top cap, but the bush buttons are not installed on the board.
