GS108 intermittent failure similar to but not BLOD

My GS108 ProSafe 8 Port switch has been working without issue for years (at least 8, I think). Last month I noticed that my desktop would not connect and the lights on all connnections would blink rapidly a few times, go blank for a second, and repeat. Thinking it was an issue with my desktop, I unplugged it and the switch continued to work correctly with 5 other connections. I installed a WiFi dongle as a quick fix, and later installed a new network adapter, which worked fine for a few weeks. Last week the blinking failure returned, but this time I had to remove both my desktop and a laptop connection before it would continue working. Finally, I replaced the switch with another of the same and all is well.

I found the "blinking lights of death" threads, which sounded very much like my problem, except that my problem was intermittent and there was no obvious failure on the board, certainly not the capacitors. Any idea whether this switch can be repaired for use as a backup, or is it bound for the trash?

Thanks,

Nick
