Thank you for taking the time to review my board. As it turns out, it wasn't my soldering but you did point me in the right direction. You correctly saw that the solder joint on the number 4 pin (from the far end) looked different. When I checked it I could not find any pin to solder to. I wicked the joint and sure enough there was no pin. I next checked the continuity between that pin on the chip and the solder joint. Sure enough it was an open. I removed the chip and looking into the socket I could see that the socket pin was bent over and inside the socket. Took some doing but I un-soldered the socket enough to pull out that pin. I straightened it out and pushed it back in. Once everything was re-soldered, I plugged in the power and sure enough the MENU button worked! Turns out the clock will run with that pin on the chip disconnected. The MENU button will just not work.
This was a stupid thing on my part for not checking all of the pins on the socket before inserting it on the board. If I had just looked into the socket before soldering it down I would have seen the bent pin and saved myself all this headache. Good lesson to me for the next project.
Again, thank you so much for your time and assistance. Much appreciated!
