Default 1970's Sun Circuit Board Test/Repair

Hi folks, first post on here as I'm having no luck at all finding anyone willing to test/repair some circuit boards I have dating from the late 70's/early 80's. I'm hoping that someone on here can either help or at least point me in the direction of someone who can. The boards are from a Sun Engine Analyser of mid 70's build date. I purchased it from an ex Sun engineer in the US who refurbishes old Sun equipment. Everything was originally working perfectly however since last winter I have been having some issues with certain functions. The trouble shooting section in the manual simply says to replace certain boards if these faults occur, ok in the 70's but not now obviously. There are two boards that may/may not have faults according to the manual. The photos below are one of these boards. Is it possible to check through the boards to determine if there are any faulty components and replace those with similar parts ?. I'm based near Aberdeen however the boards could easily be posted anywhere. Let me know your thoughts,
Thanks,
Robin
