Hello everyone, been a very stressful day kindly bear with me.

Bought a used DR5 from my Chinese supplier at a hefty premium. Before you call me an idiot I’ve purchased before from this supplier multiple times and she always sent me working products.

I noticed that on board 1 and 2 two heat sinks were dislocated perhaps damaged in shipment.
The last board works but the other two read me “0 ASICS found”. Now I’m a beginner but even if there was a dead asic like wouldn’t the other ones function?

It would also be good to mention that while it is rated for 220-240v I tested it on 120v. I wasn’t going to keep it running there but my electrician hasn’t installed 240v yet at my house and I wanted to make sure it was running first. I also tried swapping cables and all that good stuff but only the 3rd chain seemed to be working so it wasn’t a main control board issue.

Any thoughts?

If I told you nasty stuff would you hold it against me?

1) you plugged in an obviously broken piece of gear. then you posted. I wont tell you how [ guess]
2) lost heat sink means the chip will over heat.
3) you plugged it in
4) you very likely burned the chip out .
5) at best the chip was broken when the heat sink broke off.

6) not finished.
