[QUOTE="spb_stan, post: 697328, member: 43545"] It still can be battery contact oxidation in the Camera. Cleaning contacts is the wrong term for what needs to be done periodically. Metal exposed to atmospheric oxygen oxidizes to a few molecules thick normally and the resulting oxide of the metal is an insulator. Switch contacts, connectors and bare wires all oxidize and that actually protects the contact from further deeper oxidation but still allows current to flow if the oxide layer is not very deep. But when a contact is exposed for a while and in humid conditions that oxide layer of insulation can grow to be thick enough to not allow the current to jump through the insulating oxide layer. That could be your problem. The solution, in that case, is using a small about of de-oxiding chemical that strips the extra oxygen from the upper layers and returns the metal to conductivity. One popular chemical for that is DeOxit from Craig Laboratories and another is Cramolin ContactClean but another version is D-5 from the same company but in other regions of the world. Another possible cause is the memory that uses a small amount of current to maintain the settings when off, a battery in older units or a capacitor in newer one, make be depleted. If that is the case put a battery in it and do a 2 button reset which will return the camera to the factory default settings. Some data is written to eeProm memory and is not impacted, such as shutter count. To restoring Nikon D7200 to its default settings, just hold down the [ISO button] button and the [+/- Exposure Compensation button] together, until the control panel turns off briefly while the camera resets itself to the factory default settings. For a dead camera, hold those two buttons while the camera is off and then turn it on while holding the buttons down for 5-10 seconds. [/QUOTE]
