Got up this morning to a completed print of a prototype wall fixing bracket. Not sure what I think about this wall bracket, needs a tweek as channels that "fit" the rear pcb need to be a fraction wider.
Please excuse the PVC tape on screens, double sided due via Amazon today.

I might be the first to have broken theirs.
It was working before I fixed the screens.
I am working through the last things I did but card is fine. IC is fine. Power is fine.

take sd card out and clean contacts. when reinserting push the top slightly towards the rear of the clock so that the bottom of the sd card where the contacts are located pushes firmly against the contacts in the card receptacle.
If problem persists. we can try a new sd card. i’ve got spare.

ps is the second screen from the left ok? looks a bit funny in the pic? again i’ve got spares if it’s failed.
OK, sharing my experience.
SD card trick didn't work. I took the decision to unsolder and remove the SD card reader to check nothing had flowed behind and shorted it. Seemed OK, soldered it back on, and then it worked.
I have also formatted another 64GB SD card to Fat 32, original is FAT 16, this also worked.
Now to see if I can fix that second from the left screen.
I have reseated the cable, next option would be to swap over a screen and test it with another. Anything else whilst trying before I unstick them?

just check there is no scraps of solder shorting two of the small pins on the header socket. they’re very close together!
if that’s ok then let me send you a new screen.
Are you able to tell me which pins are screen two and then I can deep dive?
OP

I’ll send you a new one.
Each FPC connector has 8 pins, 7 of them are in common across all 7 displays, the 8th is the "chip select" line which is separate to each of the 7 displays.
The header pins underneath (top and bottom of each pair are connected to each other), from the left are:
1 - NC
2 - NC
3 - left screen chip select
4 - 2nd left screen cs (the problem one)
5 - 3rd left screen cs
6 = 4th
7 = 5th
8 = 6th
9 = 7th
10-16 then are the 7 connections in common to all 7 screens. being 3.3v, CLOCK, MOSI, DC/RS, RESET, GND, Back light power.
So only possibility the 2nd screen cs is shorted to one next to it and so is getting incorrect data, more likely the screen is faulty.
I'll post a spare screen today anyway.
Looking from the front, the 2nd screen from the left is connected to connector labelled FPC6

Thanks Alan, I have tested the two boards and can find no obvious short on either. I think the poor screen must have not enjoyed my handling. Sorry.

Are you connected to wifi? if so it should be getting accurate internet time every minute?
If not connected to wifi then the real time clock inside is pretty accurate, but they are dependent somewhat on ambient temperature, so can go a bit out. i’ve used them in dozens of click projects i’ve built, but never seen a 30 min drift, it’s usually a few minutes over a few weeks.

I could do with a time machine, hopefully mine has the same feature

wifi name is your SSID so i guess that’s same as your router name?
Payday is upon me Alan. I’ll send the money later.

Great stuff, PM sent.
Out of interest, what's a 'click project'?
OP
OP
typo. should be “clock”
Ahh, haha, I was thinking it was some technology I'd never heard of
Awesome service Alan, thank you for the quick replacement screen. All working
@Colywobbles can you do the case in other colours? I’d like to do a pink version for the missus
