Hey guys I fixed my other miner with the blown Ferrite bead, This was easy to fix because I knew what the problem was, now all miners are fine until I noticed 2 miners in the back of the group with the green lights flashing but the fan not spinning , Im like HUUUUHHHH So I pulled it apart and guess what was blown

2 Ferrite beads the ones Close together Not the ones that a far apart The ones that are Right next to each other sitting on the board like 2 ferrite twins, infact I saw another user on here claiming the same thing happening. I have a strong feeling that the cause for this was a bad power lead
/ Barrel ending, I now have thrown this in the bin.

I am sure the people who may give me advise will know what I am talking about,, luckily I have the same ferrite beads as I have ordered  these to repair the 1 x ferrite bead that I blew because I shorted out the red wire accidently.

Anyway I have now wasted 4 ferrite beads ... Basically the copper pads where these ferrite beads are meant to go are fukd, although they are fucked I was able to solder onto as I think there is still contact to the main board.. problem is when I did this and plugged the an on I instantly see sparkes and the ferrite bead goes RED hot I mean this all happens in 1 second and then I unplug it. Now I would like to ask the wizards in here, instead of throwing away 2 seeds as I feel I have 10 CHIPS that can mine but just need a way too, Maybe I can lower the frequency I dont know can I get some help here on a way I can salvage these 2 pods?

Visible issue 2 ferrite beads on each board blown, 2 boards & 2 ferrite beads = 4 ferrite beads Gone.... I do have spare ferrite beads but if there is a way to bypass these beads somehow I feel it wold be better, Even If I run these 2 seeds at 800Mhz  And 5v Fan Or something...

Please some advise would be great

Hello,

are you based in EU? if you check with a volt-meter you will see there is a short between 12v vcc and ground. that's why your 2 ferret bead get hot in 12v and blown instantly after plug in. i am collecting all the chip for a project which will never might succeed , if you based in EU i can buy those 2 blown gs from you if you want?

PM me plz

thanks
