Had my 50D since mid-2009 and am still very happy with it.
As of last week, I noticed that sometimes the shutter button's full-press function fails. Half-press AF works fine, but when full-pressing, the picture is not taken. This appears to be a common problem in the xxD models and I've found several videos online on how to clean the button.
Since I'm an electronics engineer, I should be perfectly capable of openening up the camera and repairing this problem myself.
However, I need some advice on whether I should clean or replace the switch.
Cleaning the switch should be not too difficult, I have the cleaning solutions readily available. (IPA & Tuner 600)
Searching on ebay for a replacement switch, I've found them available for $10 - $15 shipped.
Since most (all?) listings are from China, I'm not sure whether I would receive a genuine Canon switch (or at least the brand that Canon originally used) and what the expected lifetime of such a switch would be.
I live in the Netherlands, where (afaik) it's not really easy to obtain genuine Canon replacement parts locally.
What are your experiences in this?
Did any of you clean the switch or have it cleaned, and did it fail again after a (short) period of time?
My concern is not in the cost of replacing the switch, but in the quality of the replacement switch I would order on ebay.
