Canon EOS Rebel T7i: DSLR Won't turn on

Mon, 20 Jan 2025 17:24:47 -0700

My new 800D won’t turn on.
never dropped it has no damage on it, only thing is that is a full spectrum astro-modified camera.

After i turned the camera on it said that it could not perform sensor cleaning so i had to turn it off and on again.

So when i turned it on for the second time the camera did not turn on nor the small red LED turned on. The only thing is that sometimes when i press for 2-3 seconds the shutter button, it shows “Err” in the viewpiece and yet nothing on the LCD.

it also shows the iso in the viewpiece next to “Err”but that’s it nothing else happens. The batteries are both canon originals and fully charged

Mon, 01 Sep 2025 22:52:46 -0700

Where can I purchase a new focusing screen for my 2 Canon cameras? I have a t7i and a t2i both are in need of new clean focusing screens. Is there a specific part number? And a reputable place to purchase?

Thanks in advance for any and all help.

Tracey
