Title: Hardware issues with Antminer s5 - Specific red lights need help with diagnosing Post by: DanSwan91 on March 14, 2018, 02:19:12 PM Hi guys,
Fairly new to mining and first time posting. In short I recently bought a second hand Antminer s5 as a cheap introduction to mining. It worked, as far as I can tell, 100% for the first period I had it. However now it displays some red lights and a lot of hardware issues on my miner status screen. It still mines and at times still hits 1.1TH (full capacity) but it can drop down to zero for a few hours at a time before kicking back into gear. For example today it has averaged 300GH/s for the day and for the last hour about 950GH/s. So it still mines,just not at 100% efficiency or consistently. So there is a red light behind the front left and back right PCI connectors (If you are standing facing the fan and ethernet slot) and also one on the green hashing board on the top side, it is situated by the Antminer logo, I believe it corresponds to D5. Haven't had any luck online finding what the lights correspond to. Pictures are attached. Thanks for any help guys. https://ibb.co/btKz4c https://ibb.co/eKXfAH https://ibb.co/nornPc (Moderator's note: This post was edited by frodocooper to remove inline image tags.)

What I found though is that these have had many hard years of abuse. The best thing you can do is monitor your temperatures and see if maybe things aren't getting to hot causing it to shutdown. You can also remove the casing and look for anything that appears loose or faulty. I did notice a bit of dust to, no where near as much as mine came with ;D but it might benefit from a good cleaning Title: Re: Hardware issues with Antminer s5 - Specific red lights need help with diagnosing Post by: VRobb on March 19, 2018, 12:12:32 AM Post pics of the miner's gui status screen. That may help.
