dead monster

[kneedeeppow]

after my recent minor technical problems i have been having with my mmm v3 esc(broken reciever wire and negative connection getting super hot),my esc is now not getting power to it at all.no lights,no beeps,nothin.i had the reciever wire replaced as i managed to open the esc up mistakenly while trying to jimmy the thing of the chassis(cheap double sided foamy adhesive used to mount esc to chassis is like bloody super dooper adhesive,permanent almost) and the base of the esc opened so warrentee voided. got friend to just replace the wire.now,no go with the esc. no power at all.connect the esc to castle link and it doesnt register as connected.
can i send it in to fix or is it kaput?
cheers
