I was given a RS color computer years ago after it had been on the receiving end of a lightning strike. Already having one of these computers I proceded to check it out by replacing the chips in my computer one at a time with the ones in the fried computer( I know, not very smart). Well at the the end of all the chip swapping my computer still worked. Power supply on the damaged computer checked OK. A closer inspection of the circuit board showd that some traces underneath the processor chip had ben vaporized. Repairing these traces yielded a working computer. How the lightning burned out these traces without frying the rest of the computer was beyound my understanding. Jimmie guessing a large and fast ammount of lightning induced current traveld along the ckt trace it got hot and fried creating the open voltage no longer could pass and so never reached the other parts ie chips etc so prob by luck you had enough current to damage the trace dosn't take much, but not enough to arc over and contine damage |
