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

The link does not work, is there another link to try?
Thanks for your help.
Hi @mjackerman ,
I have no trouble with the link using Chrome, Firefox or Edge broswers

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.
