Will a 4 year old receiver still work?

I purchased a receiver 4 years ago. It worked well until I had to move the LNA for a backyard project.

I just ran across the 4 year old receiver and LNA in storage. Will an older unit still work on SES-2?

Thank you. Mark

what is the receiver using is it a dream catcher 3? send a picture of what the board looks like?
