I'm being tasked to troubleshoot a York Optiview Display on a York YT which will not boot up. Several techs have taken a stab at this before me and they have replaced sundry parts they thought were the cause of the malfunction. I understand the flash memory cards have been replaced twice, the inverter supply has been replaced along with a generic off the shelf display screen and bulb, which I am told is a York equivalent by my stupidvisor.

I haven't made it to the job yet, but if anyone knows what I should look for on arrival, I'd sure appreciate it. Changing out all the guts in this panel would be a pricey proposition, but may be necessary given the job history.
