Pioneer VSX-822 front display power supply?

Hello, I recently purchased a VSX-822 but the front display failed. I purchased another one online but the front was damaged in shipping. I purchased a 3rd one which also sustained damages during shipping but the display functions.

I installed the good display into the original receiver but it does nothing. Can someone tell me which board directly powers the front display?

Thank you in advance.

Hi!
I have never experienced an error where the display would have deteriorated.
The fault will be in the display drive circuit.
I have marked the most probable sources of error in the attached drawing.
