Hi, elshiftos.
I recently went through this as well. What a pain in the ass!
Luckily, I found that our issue with the monitor was simply a power supply. What does the monitor sound like when plugged into the wall? Does is have a slight clicking type noise? If so, you may be in luck!
We pulled the monitor out and got all of the information on the unit - including the original manufacturer's information and part numbers. We contacted them and told us that this was one of the only monitors that they've made in their history that they do not have a simple LCD/LED replacement for. (of course SSL had to order a totally custom monitor).
Where are you located?
You can PM me for my email to get some more help as I have several great options to make getting this fixed fairly easy. And they're relatively cheap too!
Best,
George Roskos
