I picked up a few on the bay and have had some success in repairing them...the problem is opening them up without scratching the plating...if yours turns and turns without vibrating it may be a broken spring which is hard to deal with...but if it winds and just doesnt seem to start vibrating then its just a frozen mechanism...the top under the razor head can be removed and a few drops of oil or some WD-40 does the trick...just be careful of scratching it...SlagleRock;1242121 said:
