Lens Repair: Schneider – Kreuznach, Arriflex-Cine-Xenon 1:2/50 Problem #1: The lens came to me with a major problem. It was in two pieces. I soon discovered that the lens had two problems. The second problem was that the lens was loose. If you held the very front of the lens firmly in one hand the rear of the lens could move or pivot a bit up or down or side to side. Solution: I removed the rear element by unscrewing…
Sony DSR 20, DSR30 DV deck Complaint: One or any combination of the following. The video tape recorder would not accept a tape. The VTR would not eject a tape. The VTR would show an error code and fail to operate. Evaluation: Remove the top cover. Most of these video tape recorder decks will do a reset if you interrupt the power to the unit.

The tape carriage when pushed in from…

I could press other buttons but they would only switch over to the new source when the button I pressed was down. When I lifted my finder the…
Arriflex motor for the S camera which uses a large power transistor on the side of the motor. Complaint: motor would race in speed. Repair: The motor must float electronically and therefore can not touch the case. There are four screws holding the transistor in its holder assembly. Make sure that each of the screws are not touching the transistor body. I had to place a very short piece of spaghetti along the screw shaft where it might come into…
