York YK Optiview Watchdog issue

[jtmk711]

Our YK chiller w/Optiview had some intermittent electrical problems that have been addressed. She ran sweet for several days, but went down last night showing a blank screen. Upon powering down and then back up, the screen works correctly and the seven segment display on the 31-02430 microboard cycles with 04-P2-05 and keeps repeating. Any ideas on the best approach?
