[OM] OM 10 Flash triggering problems

[NSURIT]

I have just recently acquired two OM 10 bodies and I can get neither of them 
to trigger the T-20 flash. On one the flash indicator light comes on and on 
the other it doesn't.  Is this a common problem (looks like a 100 0eal at my 
house) and does anyone have any suggestions for an easy fix other than send 
it ib for a repair which would cost more than the camera is worth?  The T-20 
works fine on my OM 2S. Bill Barber
