Question about Vivitar ViviCam 3915 Digital Camera
The main reason for this problem is the design of the contact plates for the batteries terminals. From inside of the battery compartment lid, you can find two tiny prong shape metal spring. One has small pieces of plastic guides for holding the positive terminal in place. The problem can develope pretty early, depends on how often you open the lid. That spring like metal piece is too delicate to be shifted out of place, even just a very, very slight shft can rest the tiny plastic pieces at the tip of the prong to rest on top of the battery terminal. Using some kind of batteries with bigger, or not too round terminals can contribute to the same problem, even the metal prongs are not shifted. Solution: Check the available batteries that you have, and use those with smaller terminal tips to power the camera. If still not turning on, then the prong(s) might be shifted a little bit. It is hard to check if the prong tips are fully in contact with the battery terminals, because after you push down the lid, it needs to be pushed in to lock. So you can only see they are good in contact before fully pressed down and pushed in. One of the best way is to use some kind of tools to remove the tiny plastic pieces at the tip, but make sure the prong tips still be able to get in contact with the terminals. I, myself just remove the two spring prongs and cut a piece of copper (the old metal tie for electric wiring) a bit longer then the inner length of the lid across, bent the copper strip slightly and sit it on top of the metal door glider. Press down to ensure the ends of the coppper strip touch and stay firm to both inner ledges of the lid. Now, before closing the lid. Cut a piece of plastic (from a ziploc bag) to a size that fits to be slided between the copper strip and the metal door glider. This forms a isolation between the two meatl pieces, the reason is the rubbing of the two metal pieces, if in contact, can cause the batteries installed to be drained faster than to power up the camera itself. This is important, or you will have a new problem with the camera. Finally, as long as you know what you want to do is to ensure a good contact of the prongs and the terminals. You may fine tune and use some other materials to achieve the goal. Your camera might have a different fault developed other than the above findings of mine that is the cause of not powering up. Good luck, Paul
