Canon EOS Rebel XSi: Was slightly working now not at all.

Thu, 14 May 2026 23:06:13 -0700

I have just got this camera from Facebook marketplace.

When I met with the seller, upon powering it on, briefly the camera settings (such as ISO and Shutter Speed) could be seen in the viewfinder, however the LCD stayed black. The flash too would work during this time.

Everything that was working:

Camera Settings in the viewfinder
Flash would actuate, not actually flash
Auto-focus

Things that weren't working:

Camera mirror
LCD

I followed the guide to replace the LCD but instead of replacing it, I unplugged and replugged the screen. When assembling it all again, I now have nothing showing, in the viewfinder or LCD. The flash is now no longer working.

Everything now not working:

Flash Actuation
Camera Settings
Auto-focus maybe??
Everything that wasn't working originally

I should also mention I have tested that the lens recieves power with a multimeter. I also checked the LCD and it recieves ~4.5V on what I assume is the main power line for it, other components recieve 3.3V and 1.8V. I have checked the battery too and am getting 7.4V+.

I am not too sure where to look now and would like some pointers on where to look next. In the meantime, I will probably end up tracing all the circuits or checking the viewfinder display to find why that stopped working.

Updated: Things Checked/Done:

Unplugged and replugged all cables on the front panel.
Checked every capacitor/volatile component.
Unplugged and replugged all cables to the motherboard, during this found that the on/off switch ribbon was almost out.
Manually actuated the flash and mirror gearboxes, they reset (and scared me) when reassembled and powered on.
Tried two different batteries, both fully charged.
Tried with and without SD card.

Thank you for your time.

Is there a chance to replace the battery inside the camera?

After being exposed to water, it looks like there is a problem with it. every now and then the camera asks me to setup date and time.

Thanks for any help!

Canon EOS 70D: My 70D is showing no or low battery level on fully charged batteries.

Sat, 25 Apr 2026 07:47:12 -0700

I have two batteries both showing 100% on the battery charger. In the camera, I get a blinking battery level with one, and 2 bars with the other. I cleaned the contacts with alcohol. No luck.

Canon EOS Rebel T3i: Canon EOS Rebel T3i has no image - bad screen, cable, something else?

Thu, 23 Apr 2026 22:43:41 -0700

The camera was dropped. Trying to figure out if the LCD is showing a backlight. I believe the camera takes pictures just fine.

Before I go buying parts, I'd like to know how to figure out which particular parts are working, like the screen, the cable connecting the screen and motherboard, and maybe even the motherboard.

Canon EOS Rebel T3i: SD card slot does not work

Mon, 20 Apr 2026 11:52:15 -0700

My SD card slot does not work anymore and I bought a new SD PCB assembly for it. (http://uscamera.com/cg2-3308.htm) Do you have a guide on how I could replace this? I could probably figure out how to do it myself, but it would make me feel better to have instructions

Canon EOS 5D Mark III: No display except when I turn it off

Mon, 20 Apr 2026 05:04:36 -0700

This might be user error (PEBIKAC) or a hardware problem.

My 5D Mark III works fine, except the display will not turn on. All other features are fine. The camera takes photos just fine. Press Menu or Play or INFO, and the display stays blank.

But when you turn the camera off, the LCD lights up like normal and shows the ‘Sensor cleaning’ image! The screen is perfectly bright and looks fine.

This one is stumping me! I can’t access menu settings to tinker at all.

Canon EOS 5D Mark IV: EOS 5D Mark IV Parts List

Mon, 13 Apr 2026 19:52:25 -0700

Hi Everybody, does anyone have a parts list for the EOS 5D Mark IV please?
I need the part numbers for the hot shoe bracket, retaining screws and the spring plate insert.
Although the hot shoe looks identical to that on the 5D MkIII (Canon Part No CB3-4683), I can't find any references confirming compatibility or otherwise.

Many Thanks, Nigel

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

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..??
