[QUOTE="spb_stan, post: 697691, member: 43545"] I was a moderator for a large Nikon community and service questions came to me usually and more often than not, the reset, even if having to do it 10 times in a row was a remedy for long stored camera bodies. The main board is generally very reliable and it is rare that a general failure is encountered but since camera techs are not familiar with electronics, a common $0.01 part failing means the entire $200 board is replaced. I had an SB900 speedlight that failed and still under warranty. The warranty shop said it needed the main processor board and it would not be under warranty because it showed signs of being dropped. It hadn't been and was in pristine condition, only 3 months old. I took it back instead of paying the $360 estimate. I opened it up and found a 10ufd capacitor had shorted. I had many so replaced it and that was 10 years ago and it is still used daily. Basically it comes down to: if it is not found to be mechanical, all techs replace the largest assembly even if it is not the problem because there are few diagnostic tests they have available to find out what the problem cause really is. If you see a repair bill with parts list that includes many parts replaced to affect a repair you can tell they "shotgunned it" meaning kept replacing assemblies until it solved the problem. It is not really their fault, there are too many specialized skills and diagnostic equipment needed to really determine the true cause of modern electronics. I have a full electronics lab in my home and can hunt problems to the actual cause but don't have the mechanical jigs to solve camera hardware problems so I can see how as a business it is darned hard to match the technical skills required and the task value. Mechanical systems have the added issue of wear and tear so some parts that work but are out of tolerance should be replaced even if they showed no symptoms. Electronics does not have that issue. Here is a shot of my home lab in a spare bedroom here in my city center apartment in St Petersburg. I brought all this and more one piece at a time in my luggage from California every time I went home for a visit.
