Hi all. I have a 1999 slot loading Imac G3 which unfortunately has passed away and i would love to revive it. the unit will do nothing and there is a faint ticking coming from the Down Converter board i believe it was killed from a power surge as a Dell Optiplex GX280s power supply has also failed in the same room. the PRAM battery is charged to a sufficient level too i fear the P,A,V board is damaged and needs working on
