I'm becoming increasingly frustrated with a solitary hot pixel on my sensor... its easy enough to get rid of it from photos, but adds a lot of processing time when you have to remove it so often (shows as bright red whenever its on a dark background).
So if you knowledgeable folk would be so kind as to enlighten me, is there any solution to this, would a good sensor cleaning or something get rid of it? Or do I just put up with it until I can afford an upgrade - its an old D80 FWIW so not exactly cutting edge.

I had this issue on a brand new body earlier this year. I posted on POTN, receiving this response which worked perfectly and got rid of several hot pixels:
"Here is the remap the sensor process:
1. Remove lens
2. Install camera body cap and power-up camera
3. Make sure a full charged battery is installed
4. Place the camera in manual sensor clean mode for five minutes. Make sure the camera body cap remains in place for the full five minutes.
5. Turn camera power off
6. Reinstall lens and test"
I don't know of this was just a fluke, or what the logic is behind it, bit it worked for me.

(canon 50d)Something to do with completely discharging the sensor i believe.
Might not need a auto sensor clean mode if...
Never tried to fix any of my stuck pixels, might give it a go at some point

..just means the old manual clean (mirror lockup so you can blow / wipe the sensor).Never tried to fix any of my stuck pixels, might give it a go at some point
Haven't got any stuck pixels on my SLRs but I do have a few on a pocket device. Only see them in RAW at 100% display if the background is 'clean'. So being in the top right corener ... skies and stuff.
However once processed and exported to whatever (typically jpeg of course) they are gone as part of the image processing.
If your editor allows you to fix spots and save the settings for repeated use (many do) that should offer a way to deal with them, when required.
