I have a Carvin BX500 amp that I bought used from a fellow TBer a couple of years ago. Very shortly after purchasing it, it starting having the infamous “protect” light fault (when the amp doesn’t turn on and stays in protect mode). Pulling the ribbon cables and spraying contact cleaner would get it working again but never enough to trust it for a gig. Now it seems to only last a few operations before getting the “protect” fault. I’m not looking to start a Carvin amp bashing thread but I would love to hear from those who have had this issue fixed. I read somewhere that the problem could be fixed by soldering the ribbon cable leads directly to the pins on the circuit board. Has anyone had experience with this?
