First can you remove the power and wait 15 minutes for residue power to drain.
Then connect the power and tell me please if it now comes on.

It is the internal mainboard that has faulted. This is like a motherboard in a computer, it controls all the components.
We have ruled out the internal power supply, residue power and the backlight as the issue which confirms this.
I am really sorry about this and you are going to have to return it to have the mainboard replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
Thank you

Expert:  Richard replied 1 year ago.
Yes it did Brian, and sorry its this result, but if it was firmware or another issue I would have had you back up and running now.
At least you know the cause.
If you need anything else, please let me know, and please remember to rate my service.
Thank you
