Hi! Very sorry about this issue! We would be most suspicious of one the solder joints connecting the display to the faceplate PCB. It's a very tricky joint to reflow (start by very carefully peeling the screen off of the PCB; try to avoid peeling the white backing off of the display panel, but it's easily restuck if it does happen) but you might be able to pull it off.

Or of course you can always email support@cooltech.zone and we will sort you out with a replacement/repair/return/whatever! Apologies again for the faulty unit!
