Hello!

As I reported recently, the backlight of my 60D suddenly stopped working, and I got an error 70 (that I can bypass). I'm more and more confident that the issue is a hardware issue, however after trying to open the LCD case+remove the plastic around the screen pivot axis, I can't see anything obvious (no disconnected/broken cable).

I was planning to buy a new LCD screen, but I heard that the problem may be a broken fuse on the mother board... for that reason, I'd like to know if there is a way to check the LCD backlight, for instance by plugging some wires to a +5V current.

Any idea how I could test my LCD backlight, and potentially discover the failing point?

Thanks!

Hello,

I've been recently extremely disappointed by the video quality of the 60D (the photos are very good, so it's not a problem of the lens or of the focus). The aliasing is crazy, I have very poor sharpness and details... It is far to compete with my basic phone (and my phone is not even crazy with photos). For instance, here is a part of a 1080p frame (left is a 60D, right is my phone):


I read "Canon is doing line skipping instead of binning, that's why you get aliasing"... Well maybe, but I also have zero sharpness and details on faces: I'd expect line skipping to render aliased small lines, but not to alter significantly quite continuous shapes like faces. And even if putting my subject slightly out of focus does help to reduce aliasing, details are not there.

Actually, if I want to have comparable images between my phone and my Canon 60D, I need to reduce the resolution from my phone down to 720p. So I've the feeling that Canon is basically upscaling a video of quality 720p (and it would explain why faces have no details). My feeling seems to be confirmed on this page: they say that the line skipping is done on the RAW bayer matrix, and therefore when you combine multiple pixels from the bayer matrix together, you actually obtain an image which is close to 720p. This image is apparently upscaled by Canon to 1080p. I never saw that argument on Magic Lantern's forum: can anyone confirm that this happens in practice?


So my questions are the following:
- currently, what is the best solution to continuously record a video whose quality/sharpness/details are as good as possible (close to the result of my phone), while keeping as much as possible the whole view angle of my lens? (the 1x1 crop modes zooms way too much, and still is not perfect) If you know some post-production trick to get the details back, please let me know.
- is it theoretically imaginable to shot true 1080p videos (or as close as possible to 1080p: I don't want upscaled 720p) on 60D continuously? I don't really mind if it's RAW, H.264, I just don't want upscaled 720p. By theoretically, I'm talking about hardware mostly, and I'm trying to understand if there are fundamental limitations or if it's just a lack of development time and/or hardware knowledge. Notably: is there any fundamental limitations that would make SD overclocking impossible for the 60D? Would it be imaginable maybe to feed the hardware H.264 encoder with a proper 1080p image? If using a custom linux kernel instead of the canon firmware could help, I'd be very interesting to know.

Thanks!
