Backup LCD Monitor Replacement

My LCD backup monitor went out over a year ago and ive been wanting to replace it with an OEM part. I did some research and cannot find it anywhere, even the dealership i spoke with gave me a different part number. My suspicion is this part may be discontinued. Does anyone know where i can find one or if there is a comparable replacement? I have tried all the basic sites, ebay, Amazon, google search.. no luck.

Other question is if anyone knows how to diagnose the problem? the screen is black, no power to it, but i dont know how to locate the wiring diagram that shows how to trace it back or if its a fuse problem.

I appreciate all the help and feedback.

 

What you're showing is not a Toyota part, it's a Rostra 250-8306. Does it plug into the factor harness up there?

Here's an original:
