TNC Exclusive – Hot pixel, Stuck pixel Dead Pixel Fix. Well after doing a bit research with Sony A7 and A9 series cameras I have found that they have a hidden feature inside of pixel re-mapping. You won’t gonna find this method in user manuals but it does work in most of the cases.
Before we begin first let me introduce you what Pixel mapping actually is.
1.What us pixel Mapping ?
A sensor is made up of many photodiodes, sometimes they fail resulting hot, dead pixels. Pixel Mapping is a in-camera preventive maintenance utility that locate and remap defective / non-functioning photodiodes from use.
A software is applied to take over the function of affected photodiodes function using surrounding working ones. No repair is performed & the process completes under a minute.
2.Pixel Mapping is hidden inside Sony A7 series, Sony A9 and Sony A6xxx series cameras
Well I do remember approx 10 years ago, I have used pixel Mapping in Sony DSLR A350, they do have a dedicated menu option of Pixel remapping which is visible in Live view mode. But in recent generation of Sony cameras this specific feature is kept hidden.
Yes, we don’t know the exact reason why Pixel mapping feature is hidden inside Sony consumer level camera. But, yes it do exist and you can use it also remove your dead, stuck and hot pixels.

Good morning Sony. Olympus has this tech since original OM-D E-M5
Why they are hiding Sensor Map tech… I think after this article they will
change it up and in next firmware update we will see Sensor Mapping menu in utility section.
Thanks thenewcamera for highlighting this issue
I’ll be damned if that didn’t work. Why wouldn’t Sony publish this fix (and who discovered it?) I was ready to fire off a call and send this 30 day old A&R III back to sony to have them fix it.
