Jobs are always first priority. Post when you can. No hurry from here R!f@@, and I appreciate your concern.
Hah !! that's why I'm the Man .I'm running out of ideas here.
Haven't seen anything odd, other than something the uC is detecting is causing it not to fully power up/enable all systems. It seems much like a stuck safety switch somewhere, but those have all been checked.
Luckily, those two are very common and low cost parts, 7400 series CMOS Logic ICs, usually under $1 each. It's just the soldering if you aren't good at it. Time will tell what U8 is to see how bad things might be.I'm pretty sure of the numbers on U2 and U3,
U2 HD74HC02P
U3 HD74HC14P
I'll get you U8 and double check U2 and U3 tonight or tomorrow, hopefully.
