Viewfinder cleaning need to replace focus screen?

[min_wong1]

I sent my 20D to Canon factory in Califonia for viewfinder cleaning.

A month just passed. The camera is now still in the factory and they

told me they need to replace the focus screen and they are waiting

for the part to be arrived from Japan. I am wondering why do Canon

need to replace the focus screen? Does the dust demages the focus

screen physically? I can't see any point that they hold my camera

for such a long period and they are not sure when will the part be

arrived and when will my camera to be shipped. They may want to keep

it as long as possible till 30D comes out or my one year warranty

expires.

I'm sure that's what they are doing.

 

Maybe they damaged it trying to clean it. Maybe you damaged it trying to clean it. Maybe they're just teaching you a lesson that they really don't like going to the trouble and expense of doing repairs that aren't actually covered under warranty. I don't think cleaning a camera is part of the deal. Warranty covers repair or replacement of defective parts.

 

If they hang onto it for a month or two, maybe you won't send it back for another cleaning.

Min Wong, are you asking them to clean it as a warranty service? Maybe the only way they can justify this is to replace a "defective" viewscreen.

Other than blowing off loose particles, focusing screens are nearly impossible to clean

without damaging or making them dirtier. If things get really bad, it's easier to replace it.

If it's only a few specks you should learn to live with it. With time you'll only get moredust

and crap on your focusing screen (unless you never change lenses).

I just asked them to clean the viewfinder under the warranty because I am selling it. I didn't use any tool that physically touch the screen and it should not need to be replaced. I know Canon is nice because they did it free for me, but just take a little bid long.
