Bro in law works in a CNC shop they where using this motherboard in one of there controller heads.
it's an EP-58MVP3C-M EPOX no power up and every large valve capacitor was leaking or swollen I did not get a pic of all the busted one i all ready started swapping good caps in before i took pics. The caps that where in the are labeled "TAYER"
the good caps are Nichicon and Rubycon harvested from a busted 755 motherboard I got out of the trash. i don't like to use salvaged caps but there Nichicon's/Rubycon and i trust them, I was not 100 % sure this motherboard would even power up after the recap but we now have post and loaded in it an OS! WOOOHOO!

all so going to have to repair my MS-5169 with the AMD K6-III+ 450 @ 550Mhz I seen a cap leaking and removed that motherboard and boxed it till i can order a large supply of caps i have a few motherboards i need to recap over here..

I am looking in to getting a hot air rework station to repair an FIC PA-2005 motherboard soon.

NEW Caps installed

Nice find! Those CNC controller boards often not cooled as well as they need to be. It's a wonder it lasted that long being abused like that. I'll bet the modern motherboard they put in there only lasts about a week, if that
