Two Issues
I have, after a few successful days and around six prints on my one week old Mk4 got the following issues after two days idle switched off:-
1. Power on, often bootloader gets to roughly half way, then screen blanks. This repeats on reset button. WILL boot though after a few tries but only first time after power supply switch cycle.
2. During print, seemingly random timing, screen blanks black. Cannot find any way to get screen back up. Print continues and completes. Still no screen, only way out is to power down PSU and up again.
🙁
RE: Two Issues
Both could be caused by a loose connection on the back for the screen
RE: Two Issues
Thanks. It appears to be running a print OK at the moment, remaining two hours. When/If that finishes I'll remove the screen connections, clean and replace, they did appear by feel to be fully home and tight, first thing I checked, but I didn't disassemble, completely remove/clean/replace.
RE: Two Issues
Probably worth checking the other end of the cable as well
RE: Two Issues (Shutdowns - SOLVED)
To put this to bed, after minimal fiddling with the ribbon cable between screen and main board, its been good for days now, several power ups a day in between other things, and no screen shutdowns.
