gp 200, powerup board diag fail

Hi pearlpdy
It seems to me that somewhere bad contact, most likely in communication of the printer PCB with the main controller. If there is no possibility to replace a PCB(s) or to check up it on other device, it is possible to try to distort sockets and to check up integrity of connections between PCBs.
Good luck.
Victor.
