Topic: Avalon module repair (Read 2696 times)
Man... I looked at the ref design and thought it was a fuse
The missing component is a capacitor. However I have no idea if replacing it will fix it.
Actually, that's an inductor, not a capacitor.
Actually (really, this time), it is a ferrite bead. Confirmed by reading the reference design.
How you manage to get things fixed, that's sucky.
Looking at this IR image, this part (white color) on the last sub module at the end of heatsink could have a very high temperature when not properly cooled, adding an exhaust fan should help
I measured a 7c degree difference between intake temp and exhaust temp when there are two exhaust fans added

I am planning to repair it myself. This is why I bought it in the first place.

https://bitcointalksearch.org/topic/m.2076500Will you document it for the benefit of the community? I mean, reverse engineer the board?
Newbie mistake.
Was that the only thing wrong with the module?
Can you share the pin out info of the ASIC and how the i/o signals are interconnected?

https://bitcointalksearch.org/topic/m.2076500dude, ship the module to BKK for repair. wink wink.

I just looked a little bit harder at the picture and the missing component looks be an inductor not a bypass capacitor.
DO NOT TRY AND POWER UP it could burn out the part right next to it.
Sorry for hasty (BAD) advice above.

The missing component looks to be a bypass capacitor.
It most likely will run just fine with out it if that is the only thing that is wrong.

So, instead of attempting to repair it, can I offer to buy this non-working module (which consists of 8 hash units total) from you for 20 BTC?
I will offer 21 BTC.OTtan already sold the unit to me.
Is it just me, or is that IC in the top left damaged?
It is a connector header, not an IC.
Edit: In case anyone is wondering, yes, I am looking to buy Avalon Modules. I have a buy thread in the marketplace.

Am I the only one that feels if you paid lots of money for this hardware than you should expect the maker of the hardware to be the one helping you getting it working again? I saw another thread where the guys Avalon board had some component burn out, and to me the first thing I would do is contact Avalon.
Have you tried contacting Avalon about this?

Hi.
Maybe someone can tell which element knocked from the board at the time of delivery, and whether the recovery will help to restore the operation of the module?

That could possibly be a simple repair, is it not ? Just order the same kind of inductor and solder it on.
I know something way more easier. Take your other modules, look for the missing part, take it off, put it on your broken module, ta-da! Its working again!

Looks like there is a bit of trace still there, some careful soldering should fix that... be careful though you'll be up shit creek without a paddle if you lift what little is left.
EDIT: good offer from Mrb there.
