Tried to turn on my board and got nothing today. Have taken it all apart and found a shorted chip from the looks. PCB won’t turn on at all, even with mom pins shorted.
Obviously would like to hopefully have this repaired before spending the money on a stormcore
I don’t know what this chip is apart of. Everything else on the PCB looks fine however. Same with the backside. No burns or marks. Just this one damn chip.
It looks like it could be repaired if the part is able to be sourced. I don’t know how I would go about getting this repaired and my hands about as steady as Michael J Fox’s.
I did shoot bkb support an email with my photos as even if they cannot help me, I hope this may be able to help them diagnose further issues with the esc.
I posted 4 photos in the main post. The last two photos are of the affected chip which has “KJNH7” written across the top. I can get more and better photo(or try to atleast) just let me know what you need.
I dont mind at all. I already know this is a crapshoot and will be replacing with a 60d. Its just big sads and high hopes to eventually bring it back from the dead.
Oh perfect I didn’t see that the first time. I think I could fix it - I don’t know what kind of coating is all over this though, kind of looks like conformal?
Should I just look on digikey for lm5060? Any idea what that chip is?
Antispark chip. You can replace it. Search Forum xenith Achilles heel. I prefer the xt90 loop key fix, as it seems the chip replacement may not last that long.
There are a bunch of threads on the antispark chip. The reason I had you read that thread was to show you it’s a known issue that can be fixed. I’ve never replaced a lm5060, I removed it. Along with the 4 little transistors above the caps. You also have to remove the 4 fets nearest to the power leads. Then you bridge all the pads. Let me look for some pics for you
Yeah let me know how it goes! My unity for as long as I could remember, it would cut out momentarily after riding over a large bump or crack in sidewalk. Until one day, it cut out and wouldn’t turn on mid shred. After doing this mod, my unity NEVER cuts out no matter what. It’s definitely more reliable now than before. If you decide you don’t want to, I’ll buy it from you.
