New D500 LCD screen goes black (Page 2): Thank you Steve. The camera has never been dropped and gets great care. I just thought maybe it was something I did.

I have done QA in electronics. These days, with so much functionality on a chip, there are not many components so the left side of the bathtub curve tends to be less daunting. But as noted, slight assembly errors can cause shorts or local heating issues.

Being in the IT field for the last longest, I can tell you that I will not guarantee any electronic component until it has been running for six months.

If there is a defect, it will nearly always die in those first six months.

After that, they will run for decades, barring electrical spikes, heat, water intrusion or physical damage.

Heat is the real killer, followed by dirty power.

Unless it is in a portable device (like our cameras), physical damage is a rare event.

Yes indeed.... and, anyone can have a batch of "bad or early failure" boards in a production run.....bad boards are usually spotted early on, prior to or during assembly or test cycles, the early board failures can sting you once the product is "on the streets".

That is why it's so profitable to sell extended warranty. The extended warranty doesn't cover the early phase and only cover the period where problem is least likely to happen.

”Infant mortality” can happen to any electronics - that is main reason for warranties.

Exactly. Nothing you would have done is a likely cause. Btw, there may have been a repair delay because Nikon got a lot of failures back from the field and needed more.time and more tested parts to fix a bunch of returned cameras.

I tracked a case for a client years ago. Humidity in the circuit board plant was slightly off and was the likely cause of thousands of failures months later.

"Just in time" manufacturing supply lines can be an issue when a production batch is bad. Since the 1980's it is rare for any manufacturer to "warehouse" materials and sub-assemblies, the materials are literally delivered days or sometimes even hours/same day/next day for insertion into mfg. line. It is a wonderful cost/efficiency methodology for any manufacturer....but in the case of larger scale failures, it can induce shortages, delay builds, and mean short supply for repair/warranty work.

Infant mortality is the biggest problem with any electronic item. They will pass final inspection/test at the factory then fail after a short time of use. Buy a new TV, leave it on for the first 48 hours after you get it home. Use your new camera a lot when you first get it to try and get the bad components to fail while it's still under warranty.

I didn’t buy the extended warranty. Maybe be I should look into it. Thank you.

Thanks a bunch Steve. 👍🏻

That might mean it had a cold solder joint. A minor repair.

That is why they are so eager to sell them. Seldom used - past danger point - so they tend to be very profitable.

Thanks Walter. They said they are replacing the circuit board. Whatever that means. 😃

Ok. Thanks. And the hope no more troubles.
