Hi everyone I stumbled on to this blog because I have a problem. broblem being I blew compressed air into my power supply Tajima C904 blew something the whole machine died I did notice a sparl in the direction of the power board, next mistake was not un plugging the machine from the wall then setting the breaker that blew in my main breaker box and attempting to plug the machine back in pow the house breaker blew again, I have the power supply apart ang the only burnt marks are behind 3 ceramic resistors on the power board I remover the resistors ang checked them with an ohm meter, they all seem to be good, but the foil on the board was broken. I re installed the resistors and jumped across the break with wire, but now I am afraid to plug it in. I have been talking to a company called Masis, has anyone had a history with them? any help would be appriciated.
