    After 2 month covid shutdown - 21T wont boot - 4 simultaneous screens of garbage

    Hi

    machines were shutoff for a covid shutdown, for 2 mos, just tried booting up the 21T. Machine was happily shut down as normal, battery was in good shape (just replaced) prior to shutdown.

    After "on"... no pumps coming on, no servos coming on. Screen comes up with what looks like 4 "subcreens" (this is a monochrome monitor, so it def doesnt have the resoloution for 4 screens LoL), looks like top left is same as top right is same as bottom left is same as bottom right - but mirrored 4 times - cant make out the words - as if it was low res.

    Looked in the back there is no error just two red bars "- -" which I understand to mean "not ready"...

    anyone any ideas ?? in a bit of a jam...

    THanks

    Do you have a control backup? Do you know how to get to the BOOT screen?
