How I broke my best miner 🙁 But did it ROI anyway?

[@ZombieCorp999]

On the control board, there should be an extra slot for the ribbon cable. Try moving the connection over.

[@SebsFinTechChannel]

I'll have a look! Great suggestion, thanks!

[@t0mcat33]

@@SebsFinTechChannel Yeah there are different connectors, this was a very good advice because when mine was faulty it was something the technitian told me to do.

[@itsjordo]

Came here to suggest this also.

[@TheMessanger]

5:08 nothing is for ever but you got your ROI WITH US!

[@t0mcat33]

I have the same miner and there is not an option to shutdown on the dashboard, at least I didn't saw it, just reboot so how can we shut it down? Also my X16Q arrived faulty when was new and did the same behaviour, faulty light every time, so after diagnosing with a Jasminer technitian it was the cable that links the control board with the hashing board that was defective. Jasminer sent one to me and everything was fixed, I don't think it may be your case but just telling my experience.

[@hcpitcher]

when i need to power down my asic miners I pull the ethernet plug for about a half hour until the hot air is cold then power down the miner.

[@rafalklepinski7372]

Good PSA Seb. Interesting to point out I ran barely profitable Antminers on a timer. They were abruptly turned on and off every single day by a timer for a year. They had no problems. This suggests the Jasminers have a poorly designed power supply or power stage on the control board. Could be something as simple as a blown fuse, NTC thyristor, or diode. I'd start by measuring voltages to make sure the right ones are being generated in the power supply. A decent quality DMM can test components for you but it can be tricky and require a lot of your time. Do preliminary checks and if it's not simple, might be faster to get a new control board (and as we miners all know, in crypto time is money.)

[@Solarmining]

Thank you for the video, I think it would be apropriate to mention new Jasminer's X44's. Let us know if you decide to repair the X16, got similar @ home and I'm hardresetting it several times in a week.

[@CrazymonkeyCrypto]

Just a heads up, dont run it with the side panel off. It WILL overheat. I ran into that issue

[@SebsFinTechChannel]

Ah good call, thanks!

[@Script_d3v]

I’ve never gotten close to ROI on any of my investments it’s a scale game can’t purchase enough at low enough cost to ROI before the large miners take over and new equipment comes out.

[@orumjack8154]

Hey Seb! I am sad it is broken that way hope it can be fixed somehow.I got 4 of them and they are solid and working well so far.Also ETChash and Ethash algorithms pretty stable.I wish i would have spent all the time and money for them instead of Kaspa as it never makes me happy because of unstable ROI.Now i am waiting for X-44 series looks awesome =)

[@SebsFinTechChannel]

Yeah I love this thing, hearing some suggestions in the comments I'm hoping I'll be able to fix it.

[@ich_16]

if you are going to replace the control board cuz jinglemining sell them make a vid while so 😁

[@SebsFinTechChannel]

If I buy a replacement one I’ll definitely make a video!

[@ZaPirate]

a power cut shouldn't brick the device. Is this a Radeon VII?

[@SebsFinTechChannel]

LOL right!

[@ronwatkins5775]

I went looking around the X16-Q gui and I couldn't find any way to "shutdown" the miner. I have been turning mine on/off daily due to heat buildup doing it the same way you have been. I have not had any failures yet, but now im wondering what is the "proper" way to shutdown the X16-Q. Have you found a way for the X16-Q to be properly shutdown? Is there someplace in the GUI? The Miner->Work Mode menu doesn't have a sleep option, and they only have a reboot option on the main miner menu.

[@SebsFinTechChannel]

Oh interesting. I really thought there was a "sleep mode" like on most ASICs. Maybe it's not my fault that the miner broke then and I just got extremely unlucky?

[@ronwatkins5775]

@@SebsFinTechChannel If you find a way, I would really appreciate knowing it. Im cycling power on my X16-q's all summer. I live in the Arizona Desert which sits between 110F and 120F for parts of June, all of July, Aug and parts of Sept. I can't run them 24/7 due to the heat. I have 5 of them and they are generally off 8 hours during the late morning through evening hours.

[@SebsFinTechChannel]

Unfortunately I can’t investigate because, you know, mine is broken 😶 But I’ll ask around!

[@ZombieCorp999]

​@ronwatkins5775 You can try on efficiency mode. They will run at 110 but not much higher than that.

[@TheFunesk]

Have you tried resetting it to factory defaults

[@steveg5832]

On mine there is no option to sleep or power-down, only reboot and reset. Not saying frequently turning it off didn't have an effect but it looks like that's the only way you can.

[@SebsFinTechChannel]

Oh interesting. I could have swore this thing had a sleep mode in the drop-down menu for different hashrate modes (low power mode, high hashrate mode, sleep mode, etc.) is that where you are looking?

[@xampolas]

@@SebsFinTechChannel No sleep/mode on Jasminer X16Q. the only way is indeed via the power-button... now you got me scared of turning off mine O.o...

[@critten9]

@@xampolas yeah i dont think theres a power button in firmware - i usually just flip the power switch off. shouldnt break because of this!

[@kryptosun1290]

Agreed! I have several X16Qs and there is no software shut down / sleep mode option... So you can stop beating yourself up, something just failed;) I read a lot of interesting leads in the comments, I hope you'll follow up on the fixing of your X16! I do shut down mine daily when power prices go up during daytime on cold winter, so you got me worried I was also doing something wrong. But I don't think there's another way...

[@jafuentes89]

I just order one what kind of power cable it take for us?

[@SebsFinTechChannel]

Just a regular C13 cable 👍

[@jafuentes89]

​@SebsFinTechChannel thank you i got it for 1600 so hopefully i make my money back since everything is going down i was able to get that price

[@SebsFinTechChannel]

@@jafuentes89 wow that’s a great price

[@TimeSum21]

Put a thermal camera on it while it's up and running. That way you can see if there's a short. Of course you should talk to technical support.

[@DarKayserLeo]

3:09 OMG xd that's a big mistake

[@SebsFinTechChannel]

I know......... :(

[@popoviciioan8705]

Change power supply. Try with another power supply.

[@SebsFinTechChannel]

Interesting idea! The PSU in the X16-Q is integrated, so I'd have to look up what kind of PSU I could replace it with. I've also considered ordering a replacement control board to see if replacing that fixes it.

[@MrButuz]

These are designed to just be turned off on the back power button which basically jus cuts the power same as you did. I thin it's just a coincidence that you think it was you cutting the power that bricked it? Sad though, hope you can get it fixed. Have you tried powering it with a standard ATX power supply? Be worth a try just 6 pin connectors all round.

[@VikTortor]

the only thing could have died from switching off the mains plenty of times is the PSU - run a dozen bitmain asics from solar for a couple years only the psus were dying after a while

[@TechnicNerdAT]

check the power supply, if every power lane is there, looks for me like the mining cards get power but the control board not or the other way PS i dont think thats ur fault! because what if there would be a power outage??? would this break the same way? i would say the fault is on ur side if u would do a update and switch off exactly than. but not if u only switch off the power!

[@SebsFinTechChannel]

Interesting I’ll definitely check that. Great suggestion, thanks!

[@fais2525]

You can sell it 800-1000$ now cuz new miners are cheaper now

[@MrSkinny602]

try replacing the power supply with a know good. Sometimes the power supply's just go bad.

[@axe_rocker]

you are too honest :) which are good

[@HRMOHAMMED]

Whats about ipollo . ........... no such option

Check in the hashrate options that’s usually where it is

can you send it if you are in Europe?

[@SebsFinTechChannel]

Well I’d like to try to fix it first 👍

[@nineteenhundredninetynine1916]

When my X16 arrived, it mined exactly once and then no more. After a lot of troubleshooting, it turned out that one of the current-carrying screws had come loose and the hashboard was no longer connected to the PSU. The power connection to the PSU is not so obvious because of the metal brackets. Check this screw, maybe you have the same problem.

[@sageaces1921]

buy a new or used motherboard for around $200 USD.
