Looks like only 1 chip is working. Using version 3.99 of BFGminer (maybe even your version in your screen shot), you can go into Manage Devices and scroll through the 2 grisdseed units and confirm if it's just one chip submitting shares. Sometimes rebooting the USB and Miners will correct 1 or 2 chips not responding...sometimes only a pool/coin change can kick it back to life. But I've never seen just 1 chip working and the other 4 dead. If you can't get it professionally brought back up to spec for less than $150, might be time to cut your losses and learn from the mistakes and buy a new miner. I am going to take one of mine into a local laptop repair shop that does SMD resistor repair to look at my dead one. I only messed with it because it was the black sheep of the group that was working well enough (sometimes) not to send back under warranty...so I went ahead and FUBAR'd a volt mod to see what the board would do.
