Canon EOS Rebel XSi: Mode dial broken at the shaft

Fri, 27 Sep 2024 10:35:34 -0700

Mode dial broken at the shaft, could ifixit do a video on how to repair it and the tools I need?

I've been looking for a repair video, so far almost nobody does it and only recommend super glues or gasket makers...

So I'll be undergoing that daunting task...

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.

Canon EOS Rebel XSi: Why does my screen flicker like this after about 10 seconds?

Thu, 27 Feb 2025 04:59:22 -0700

Why does my screen go like this about 10 seconds after turning it in, and then soon after the camera shuts down and sometimes gives an err99? Thanks

The camera was working fine on all modes but now it does not auto focus and not take a picture when I hit the shot button- nothing happens. I don't know if I reset something or there is a malfunction.

Canon EOS Rebel XSi: How to fix the lcd display?

Tue, 09 Oct 2018 23:04:57 -0700

The LCD display does not function - it just shows white lines. I see a guide for replacing the LCD, but where do you find the LCD for replacement. The guide shows “no parts needed”.

Canon EOS Rebel XSi: My 450D doesn't power up - is there a schematic?

Thu, 18 Jan 2024 21:56:01 -0700

Hi Forum,

Recently I bought 450D cheap on ebay ("for parts, not working")

It was hit hard by previous owner (probably fell on concrete), such that power board was bent and probably some components were cracked as well. I replaced the board with another one (probably working, I had to repair the FFC connector latch, it was broken), but when putting things together, I reversed FFC cable (!!).

Camera was beeping every couple of seconds, and there was no other activity.

After connecting the FFC correctly, now there is no beeping but the camera does not power up,

Does anyone have schematic diagram of this camera, or at least a list of measured voltages/waveforms that would help me diagnose and/or locate the problem on the component level? I don't have other spare working boards to try fix this by replacing boards.

Thank you in advance!

Bojan

Canon EOS Rebel XSi: Will not turn on unless...

Sat, 15 Jun 2019 00:59:02 -0700

So I have a canon 450d as mentioned and it will only turn on after the Battery has been taken out and put back in (It can even be the same battery). Otherwise If I turn it off and then try and turn it on later it won't show or do anything. I was wondering if anyone had any suggestions?

It has been fixed and I thank you.

Canon EOS Rebel XSi: The camera is stuck on TV mode. Dial broke off.

Sun, 23 Oct 2016 09:30:07 -0700

The circular dial broke and came off. I put it back on and it no longer works. Camera is stuck on the TV mode, which is usable, but I would prefer being stuck on M mode. Is there something I can do to change it - or else?
