I'd open them up and have a look at the capacitors for bulging and leaking. 1997 is in the "capacitor plague" years when a huge load of counterfeit electrolytic capacitors were on the market and just about every company making electronics stuff ended up with some. Best case is the capacitors can all be replaced and the motor driver, computer, stereo etc will be back in working order. Worst case is the capacitors going off caused improper voltage or current to flow here and there, frying other parts. Or some times the capacitors would short (frying other parts) or even explode. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
