Does it "blink" on then off real quick when you power up the system? Could be the LCD or the inverter (I would lean towards the inverter). Sometimes it is just best to get a rebuilt/repaired control panel than several service visits swapping in/out parts.

Could be boot rom, RAM or main controller causing the issue. The RAM has caused the issue on this model in the past so I would start there and try replacing what you have on hand.

Try reseating it's connector on main controller, that is what it is plugged into...
