Colleagues, I need help with an old 50VT problem. The camera is old, the problem is new.... The little slider near the top on the left side which changes from Normal to Plus (+) and Minus (-) and Anterior (A) is stuck in the Minus position. Lately it has been extremely difficult to move, why ? Maybe it got bend? I pulled it all out to "A" but could not slide it back. Something "clicked" sounded like something fell in the way, preventing it from sliding back in. A local dealer rep tried to fix it but was not able to solve the problem. Did anyone of you experienced a similar fate and was able to fix it ? Any advise is very much appreciated.. Thank you Peter Peter L. Breit, CRA.
