Jumper t8sg plus v2 display fault

all setup and ready to go flying switched on my t8sg v2 plus and got a scrambled screen worked fine last time i pick it up. anyway tried to work out the issue i updated to the latest firmware and still have the same screen fault anyone have any ideas i checked the ribbon cabble all seems fine. i think it might be a mainboard issue.

can i buy a replacement mainboard ???

just tried that no difference

no this is the screen i get in usb mode...
iv tried latest firmware and files
also formatted through usb and reinstalled files
dismantled the radio and checked all cables and ribbons
i get the beep when powering up but still no display any more ideas anyone ???

Smart guy thumbs up thank you it was just a broken track on the ribbon my repair attempt just made it worse
is there a replacement screen avalible anyware

Ps. T16 on its way
