Digit Youneed to not put a lot solder on settings buttons at all I stopped using solder for those a small strip of box tape across them! If you soldered them lightly then maybe they've fallen off? Happened to me. I've built 3 of these soldering them can cause more problems than its worth I held then 1st with scotch tape then a strip of box tape worked better than solder by far!

Digit Hey I twisted 3 22 OHM resistors tougher solder them then replaced one side of the speaker wires with the 3 resistors and walla problem solved built 5 of these all only said "IT IS" then LED'S would blink out. Sounds like you might of got your Crystal TOO HOT. All 5 I built keep perfect time. They need to redesign these to solve it.
