Check the Main Controller PCB LED101 which is ON during normal operation. When you experience a blank LCD screen, inspect the Main Controller PCB LED101, if the LED is OFF, then replace the SRAM PCB (FG3-3669-000) which is mounted on the Sub Main Controller PCB.
Check the connection between the Sub-Main Controller (J1303) and the Main Controller (J1209) to see if they are seated correctly.
Ensure that the voltage between the neutral and ground poles is 1/2 a volt or less.
Could also be a Power Distribution PCB issue
