Maybe I missed it in the threads above, where on the inside is the red led that should be covered? I want to be proactive with my T5i.

Hi Jerry,

 

I tested my modified T5i camera at room temperature and the 10 minute dark at ISO 800 had no signs of amp glow even after a heavy stretch.  Image is below.  I had the display turned off using the info button, had black electrical tape over the viewfinder and with the body capped.  I did nothing to the red LED light.

This is the problem I am having with my modified and TEC cooled 450D. I have the LCD live view turned off and running it with an HDMI screen on the outside of the camera. nothing I try seems to get rid of this amp glow !! It sucks to say the least :-(

If I am looking down at the senor and rotate the image 180 degrees the amp glow seems to be coming from the right side bottom corner opposite the cooler and heat exchanger.

Dose anyone here know of a fix for this image destroying problem ???

This link may have helped me ?? I think I know where that amp glow is coming from now.... it may be coming from the Red LED on the right bottom of my camera... it just so happens to be in the same place and corner to where I am having this problem.

Yep.  Absolutely agree.  Blacking out that LED should fix your problem Tom

Bringing back this 3+ year-old topic, because I have just in the past couple of weeks started seeing the 'mystery glow' in my unmodified 700D. A google search for '700D amp glow' turned up a bunch of forum threads of similar vintage, so before I try to read them all end-to-end and before I do anything like open the camera to goop up the LED "Access Lamp", thought I'd post here to see if any of the old hands know the true ending to this saga (if any).

 

This is a 60s iso12800, just the unstretched photo compressed down to a small jpg. Taken inside a box inside a dark walk-in closet inside a darkened (but not dark) room, using an intervalometer from outside the closet. No lens, black electrical tape over the viewfinder window, battery power, SD card in the slot. I assume the LED stayed on through the exposure, as that's the behavior when I'm watching and do not believe it to be Schrodinger's camera.

 

Same result when the LCD is at lowest brightness, open and pointed away as this one, taken with the LCD closed. I always assumed that turns the LCD off, but I will go through the manual to see if it says anything about that.

Interesting, I've never had any amp glow with either my 80D or 600D.

We can be pretty certain it's not the LED "Access Lamp".  The access lamp is at the bottom right of the camera (viewed from the rear) but the 700D glow appears on the left hand side of the sensor.
