Canon EOS 30D: Why it didn’t shoot with AF on?

Fri, 03 Apr 2026 09:27:00 -0700

My EOS 30D didn’t shoot with AF on.

First trigger in AF works good.

With manual focus it fires.

without lens , the camera shoots without problems.

if I change the lens , nothing change.

I think the problem is in the camera and not in the lens.

can you help me?

Thanks

Andrea

Canon EOS 40D: My 40D suddenly will not turn on

Thu, 26 Mar 2026 23:56:28 -0700

My 40D was working fine. I did not use it for several days and when I went to use it, it does nothing. No lights, not screens, nothing. Its as if its not turned on. I have checked all the switches in the battery door, replaced the 3v lithium internal battery. I've checked the switches in the card door. I've tried new batteries and new cards. Fully charged multiple batteries using multiple chargers. I've tried it with and without a lens, still it does nothing at all. No lights no displays of any kind. Its as if it just will not power on at all. Canon no longer repairs the 40D and there are no repair shops anywhere near me. The camera just suddenly went dead and does nothing..??

Canon EOS Rebel T3: Mirror is sticking and causing black bar

Tue, 10 Mar 2026 17:21:55 -0700

Hi, Whenever I take a picture there is a black bar blocking most of the image or even just half. Normally this issue would be caused by a failing shutter or the shutter sync but I have determined its the camera getting stuck. When I put the camera down at the ground and take a picture or use live view, the picture is completely clear, when I point the camera up or eye level, the mirror gets stuck halfway, this can be seen with the lens off. Is there any thing I can do to fix this? Is it a bad return spring or some other issue.

Canon EOS Digital Rebel XT (350D): CF card error message

Thu, 05 Feb 2026 03:08:45 -0700

I've been having this CF card error message on my 350D pop up each time i try to use it.

I had a root around, and I believe the problem is a bent card reader pin inside the system itself.

Is this repairable? if so, how much, if it isnt a home fix.

thanks!

canon c100 mark ii: C100 mark ii picture is not sharp and color is washed out

Sat, 03 Jan 2026 22:50:56 -0700

I’m setting up a podcast and I bought two other C 100 Mark two cameras used to match my current one

One camera is just as sharp as my original. The other camera is not as sharp. The picture quality is slightly less sharp. it’s noticeable because I’m using it as a podcast.

Is there anything I can do to improve the picture quality and sharpness hand in color. The color seems washed out also.

I have the same lenses and I change the lenses on all three cameras and the other two cameras look good with all the lenses and the other one is not as sharp, no matter what lenses on the front

And I have professional lighting the other two cameras look great

EOS-1D mark II: Canon EOS-1D Mark II DC/DC board F201 location

Mon, 22 Dec 2025 08:39:43 -0700

Hi everyone,

I’m struggling with a dead Canon EOS-1D Mark II . The camera is completely unresponsive. I’ve already tried all the basics: fresh NP-E3 battery, checking SD/CF door switches, and replacing that "terrible" internal backup coin battery.

One weird symptom: the battery icon on the sub-LCD blinks very briefly ONLY when I pull the battery out.

I suspected a blown fuse on the DC/DC converter board (CG2-1255) and took it out. According to the service manual, there are four fuses: F001, F002, F003, and F201. I’ve already located F001, F002, and F003 and confirmed they have continuity.

However, I cannot for the life of me find F201. The area indicated in the service manual seems to be occupied by a component that looks like a diode (marked "T1 61" or similar), and I’m hesitant to bypass it without confirmation.

Does anyone know the exact physical location of F201 on this board? Any photos or guidance would be greatly appreciated!
