Dead Pixels?

[mach1]

Hi,when i switch my 450D on and have no images on my card i have noticed quite a few white dots appearing on the screen could this be dead pixels?if so is there any remedy for this.Thanks

Do you mean on the rear LCD screen? And is it when you're viewing the settings menus?

[mach1]

Yes rear LCD screen Chris.They are noticeable when i switch the camera on and the card is empty of images there are ouite a lot of white dots scatterd about.I have a Giottos screen protector added i would not think that has any thing to do with the problem.Thanks

I doubt it's marks on the LCD protector. You can obviously check by taking it off and seeing if they're still there!

It's a bit odd. If you can take a photo with something else and upload it that would help. Is the screen on when you can see the marks? If so, can you see the marks when the camera is off. If the screen is on, what is it displaying. You say the card is empty but the camera will show the status screen normally. Can you see them on that?

Sreen is on and its saying NO IMAGE.I just had a look when its on menu and you can see some dots on the darker parts of it,cant see any when the camera is off,there dosent seem to be any on the photos i have taken.Which makes me think its somethig to do with the LCD screen

[chris-p]

You need to have a look through some of the menus and various screens and see if the spots are there all the time and if they're in the same place.

If they are it sounds like the screen might be faulty. Do you have access to another camera that you can use to take a picture of the screen?

I have a Canon S90 compact, its whether i can get a good enough photo to show the problem,i will upload it if i can Thanks for your input Chris

Looked at screens through magnifier, spots all in same place Chris,faulty screen i guess.No doubt will cost quite a lot of money to put right,so i will just have to live with it.Thanks for your advice Chris

It's not unusual to get dead pixels (which are black) or stuck pixels (which are white or RGB as the pixels colour(s) are stuck 'on') and all manufacturers have an allowance before they'll take action (but it's usually just a few). The reason is that it's very difficult to get 100% working (even sensors can/will get this problem)

It has been fine up till now Markulous 4000 shutter actions top whack. I asked in my local jessops shop about the problem with my screen, and he had never heard of this problem over the last couple of years of selling quite a lot of the 450Ds.Perhaps i should look online to see if i can find anybody with the same problem.My the way my camera is about 2years old.
