I have a problem with my sp20 checking suddenly trailed off and I find that the fan is off reviewed disarmed and I find a circuit according to sample photo .. I turn the direct fan on. try to put the sp airing live and not mine .. I guess it's because the target reconoce the fan is not turned on and off. now my question is .. that has repair o donde se puede encontrar esa tarjeta

huh?

looks like a voltage regulator was fried, you have to be pretty stellar with soldering to even attempt this fix.. not sure man, bummer

its not my fault

huh.. your one smart cookie.. i like cookies Tongue

i myself have only recently begun dabbling with circuitry through messing around with arduinos and pis, but i still have ways to go

fiddling with the sp20s i find that just letting them sit sometimes for a few hours, when they dont want to run, will more times than not fix the problem.. i imagine im just waiting for the ambient humidity to change whereas you actively change it

what made you think to try this in the first place?

I stumbled onto it by accident. Mine are usually kept in the garage (no HVAC). After the failure and when I couldn't get it to boot via SD in the garage I brought it into the house take a closer look at. It booted perfectly fine in the house over and over again. As soon as I moved it back to the garage it wouldn't boot. At first I suspected there was a temperature sensitivity issue (too hot in the garage) so I tested for this failure mode in the house using a hair dryer to make the SP20 hot before starting it. It still booted in the house even after being heated, so it was not a temperature issue. That left humidity as the only difference between the environments, so (after a few other things) I tried using the hair dryer to "bake out" any moisture prior to starting it in the garage. It worked (and reproducibly continues to do so)!

What I think is going on:

Surface mount ICs, especially BGAs, are moisture sensitive (how much can be found as MSL [moisture sensitivity level] on the datasheet). Their plastic case can absorb moisture out of the air. This is normally only an issue during assembly, as any absorbed moisture during part storage can crack/destroy the chip during the reflow process. To prevent this, chips exposed to moisture are preheated to remove moisture before reflow.

I can't prove it, but I highly suspect that one of the chips on the SP20 controller is extra sensitive to moisture. As long as the unit is running hot it isn't a problem, but as soon as it is powered down (like in an outage) moisture from a high humidity environment rushes into the chip and it will not restart. In the worst case, the chip destructs and the controller is permanently dead. In my case, I was left with a marginal one that will still restart with some hair dryer assistance to remove the moisture. If my hypothesis is correct then a conformal coating may be a way to prevent the controller from dying in the first place, but some other things would need to be considered before recommending it.

...today after i restarted one of them after tweaking voltage,yellow and green lights didnt light up at all,so after alot of differenet tries to recover it with switching power cords,restarting,sd card rebooting,and so on,i concluded that my controller board on top of the miner has probably gone.So i replaced this board with other from different miner,lights are up and miner starts normally,so my question is can this controller be repaired or i shouldnt bother...

This is going to sound crazy, but I have one miner which behaves exactly like this after every power outage (fan spins and Ethernet link lights, but no yellow/green miner LEDs light and it just sits there doing nothing). I managed to get mine working again with a hair dryer. Chances are it will not work for you, but it can't hurt to try:

1) You will probably need to use a SD boot card (not recovery)
2) Before powering up the miner heat it up with a hair dryer on the high setting for 60 seconds (blowing it into the air intake is fine)

I've done this with mine three times now and each time it started right up. Like I said, it can't hurt to try it.

Hello people,as i only found this thread usefull about spondoolies sp20 and all related to it,i may ask a little help from this nice community digging in same hole...
Well i have several sp20 miners,some moded with different fans to reduce noise and cool better,they run at about 1350ghs prox each,i do manual volt settings accordingly to temperature as fans are not auto they run on full speed,they served me well couple of months now,but today after i restarted one of them after tweaking voltage,yellow and green lights didnt light up at all,so after alot of differenet tries to recover it with switching power cords,restarting,sd card rebooting,and so on,i concluded that my controller board on top of the miner has probably gone.So i replaced this board with other from different miner,lights are up and miner starts normally,so my question is can this controller be repaired or i shouldnt bother(seems that controller board is getting power as some small leds on the board are up when board examined closely),or i need to replace it,if i do then i would ask any of you if could have spare one so i can buy it,it would be a really great help,as this miner sits now without work ,and you all know how they like to work;)

Thx for any help you provide me...

I bought an used SP20. I booted it with a microSD and restored all.

Now I cant start the SP20 without the microSD in.

can somebobu help me?

try formatting the sd and rewriting onto it.. that works most of the time for me

I think you misunderstood. I cant start the miner without the microSD into it.

Are u using the recovery or boot image?

recovery did not work. Im using boot.

i typically have that problem as well. only once has recovery actually worked for me, but the boot image is designed only to be run off the card and not to fix the problem on the miner itself. theres no way to run it without the card unless you get the recovery image to work

SP20 not working since this am.
I can see it on the network, ethernet is green, but I see double blinking of the yellow light.

can this be fixed by SD-card or is this most likely the controller?

If SD-card, then is there a procedure for a Mac (preferably) or Windows (7 or XP)?
Thanks

Yeah, check http://www.spondoolies-tech.com/blogs/technical-blog/13098521-sp10-sp2x-sp3x-recovery-sd-card-boot-sd-card-creation-instructions. There is a procedure for Mac/Win/Linux

Thanks. It miraculously recovered to a state where i just needed to restart the cgminer.
Of some use: i think that one ASIC started to malfunction and overheat (others are OK) which resulted in some software malfunction, so i simply switched it (bad ASIC) off; mining resumed on 7/8 ASICs at ~1090 Gh and ~600w at the wall. This SP20E was mining since December, so I guess it simply started to age a little.

The more I look into this, the more I hypothesize that humidity/moisture is causing my problems (since temperature is irrelevant in a low humidity environment). I checked the humidity today-- it is 91% (much higher than usual - yikes)!

Depending on the MSL, the plastics of ICs can absorb moisture (it is standard practice to bake ICs that have been exposed to moisture prior to reflow soldering to prevent damage). I suspect that I have a marginal IC on the controller that starts fine in a low humidity environment (HVAC) or when I "bake" it with the hair dryer prior to startup in a high humidity environment.

I wonder if something as simple as silica gel packs placed inside the miner near the controller would extend the life of the controller boards?

I have 50-60 percent humidity during a lot of the summer. I have had no problems, but it's not next to window or anything.

So not as extreme as 90+ but it can handle mining in at least some humidity with no issues.
