Hi @mjackerman ,
It’s looking like a mainboard problem.
Here’s a link to the service manual (I think).
It has troubleshooting flowcharts, which may be of some help

Hi @mjackerman ,
Does this occur on all input types?
Do the menu screens work?

Yes, occurs on all inputs.
Menu screen does not work.
I removed the back cover and checked power supply voltages and all appear to be normal.
Backlite does come on.
