I found this thread by a google search as I have an OM10 which was my late brother-in-law's, and hasn't been used for 8 to 10 years. It too has the same shutter problem as described exactly by the original poster..... but I have good batteries in there, and even put 2 new LR44s in to check and it still wont advance.
The battery check light is fine, so I'm wondering if there could be a mechanical fault with it.... can anyone give me some more tips please?
Thanks
William
