Before you replace the Pico in your PicoCalc, disconnect the FPC ribbon cable from the screen and remove the mainboard from the case. This was specified in another thread, but it can’t be stressed enough. Plugging a board into the Pico’s socket puts stress on the mainboard which then flexes enough to crack the screen. Another tip is to double check the alignment of the screen before screwing on the case back. If the screen doesn’t sit squarely in the opening, fastening the case back could cause the screen to crack. The screen isn’t particularly delicate, but position of other components can push it past its design limits.

Also if you accidently press the keyboard while screwing the case together the screen misaligned quite easily.

Just got my replacement screen and happy to report that mine is up and running again 
Ty to Alex for sending it.
Delivery was pretty fast to the UK. Sent 4 days ago and arrived today
And yes - don’t do what I did (before this thread raised the issue!)
I completely agree with the main post →
DC the ribbon cable so the screen doesn’t move.
Change Pico boards away from the case and screen and carefully check that it is seated properly before putting all back together again 
Basically, don’t put any pressure on the screen at all!

Tip: tape down the screen to the front half of the case if you want, but DO NOT use any sort of hard glue (even hotglue)–case flex will put pressure on the screen and cause uneven backlight.
Thanks. I’ve emailed them, hopefully I’ll hear back soon.
