Never had this with Nikon or Canon before.
Where do I get this firmware? How can I do it? I talked to customer service they suggested I swap out the camera.

Change the camera. I've seen unhappy people too often regret decisions. Make sure it's all lenses First.
Dont let them say repair.

This is weird, I just tested it again in my room and it appears to be gone?
How could this be?
It was there last night on my shoot but today its no longer there? Self fix? Could it be a stuck pixel that became unstuck? like on an LCD panel?

Is it lighter now in your room? Many stuck pixels only show up at higher ISO or longer exposure.
I guess it's also possible that there was a bit of something on the sensor that worked its way loose.
The "firmware update" that I wrote about before would need to be done by a repair shop. I have a stuck pixel on my Nikon D90, and I was given a $65 estimate to re-map the sensor (which seems high to me, but they have the equipment to do it).
Try going to a dark room and take a picture. If it's there, then I agree with the other poster that taking it back is the path of least resistance. However, I doubt the replacement won't also have dead pixels, they'll just be mapped out properly.

At least once a month dead pixels are cloned out (unlike cameras from the 2 big brands last time I checked), without a need to have your camera fixed. If it's gone, it was probably automatically removed.M Powered wrote:

I tested it at the same ISO setting and what not. It disappeared, got me scratching my head. Definitely not a "dead" pixel, but more of a hot pixel like you see on your LCD.
My guess is that it worked its way loose after some shutter actuation's.
wait, what? how is it automatically removed without me doing anything?TrojMacReady wrote:

Periodically,the camera will take a picture when you turn off the camera.This picture will be totally black.If the camera discovers any stuck pixels,it will automatically map them out.This is all done automatically without you having to do anything.Hope this helps.M Powered wrote:

It's a hidden agenda Sony has put into the firmware.
BTW, I wouldn't mind to have that model on several of my photographs...

I believe the older Sony DSLR's had the option in the menu.Now this is done automatically.I pretty sure I read this on this forum somewhere.Try googling Sony pixel mapping or remapping.I'm not sure if other manufacturers offer this function.M Powered wrote:

If you've ever turned your camera off and you here the shutter actuate,that's the camera running this function.

Looks like fun and intrigue.
Did you lock her out on the balcony?

I was gonna say that with a model like that in the picture, you actually saw a dead pixel!!??Bart7D wrote:

I think it used to be in the manual, but I'm not sure if it's still mentioned. The function is still there though on all Sony models.
An often mentioned trick (it works, I've used it myself), is to forward the date of your camera by a month or so if you encounter a dead/stuck pixel. That way you don't have to wait weeks for it to be gone. After the fact you can return the date to the original one, the dead/stuck pixel(s) will remain mapped out.
At least until recently, you'd have to have your Nikon camera serviced ($$$ when out of warranty) to have dead/stuck pixels removed. Here's a recent thread mentioning the latest top bodies still not having a fix.
From what I've read, Canon now offers an option to manually remove them with the sensor cleaning function, at least in the top bodies.

Interesting. About an hour ago, a photographer sold his D800 for the A99. He told me that he had a hot pixel on his camera that he just picked up. His goal was to replace it with another A99. He now says that it vanished.M Powered wrote:
