Here's what I've looked into:
Voltage out of the regulator is 5.0v
Voltage at pin 7 of IC1 is 4.8v
Pins 8 and 22 of IC1 are grounded
Pins 15 and 16 of IC1 have no voltage
I've attached some pictures of the front/back of the board. I ended up taking the buzzer out to test. Added C10 and R2 because that's what the troubleshooting guide suggests. Any ideas?

Re: Ice Tube Clock - No Beep
The direct flash makes it hard to judge the quality of the solder joints. If you can shoot those again near a window in the daylight that would be helpful.

Is this any better?

Re: Ice Tube Clock - No Beep
Soldering and component placement looks good. It is possible that your processor firmware was not installed properly. If you contact [email protected] with a link to this thread we can send you a replacement processor.

Not to detract from Bill's suggestion but the soldering on the controllers socket looks a little iffy on a few pins. I also would re-solder the I.C. socket as well and see what happens.

Re: Ice Tube Clock - No Beep
I think I am experiencing the same issue here; the symptoms seem the same.
The voltage out of the regulator is 5.04v.
Voltage at pin 2 of IC1 is 3.98v, pin 7 of IC1 is 4.96, pins 15 and 16 of IC1 read 0.06v
I am not sure how to check that Pins 8 and 22 of IC1 are grounded, but I don't get any reading from them. (0v)
I did not find the troubleshooting guide saunter makes reference to, so I have not added C10 and R2, and I have left the speaker soldered on.
I re-soldered the pins on the socket and on R1 and the speaker.
Attached are pictures of the top and bottom views of the board. Is there something else that I can check?

Re: Ice Tube Clock - No Beep
@anro - The assembly looks pretty good so far. If you are not getting a beep, it is likely the processor. If you contact [email protected] with a link to this thread, we can get a replacement out to you.
