Still nothing.black....does it have anything to do with updating its firmware?...should i?

[Walter Schulz]

If you insert a card and close compartment door is there some LED activity?
Starting in C-modes doesn't work either?

[porsha12345]

Unfortunatly no.the only way i can see anything is if i attach a monitor with a HDMI cable to the camera...other than that its black

I've encountered this LCD black screen once on the 7D and followed instructions from Walter Schulz some time ago and managed to get it working again.

At least have faith in yourself and don't give up trying!

Then you should bring your camera to a Canon service...

Last night, g3gg0 found a way to access the display from the bootloader (without relying on main firmware). This would be a good diagnostic tool - it will tell whether the problem is from the LCD hardware, or some software fault. So if you are not in a hurry, I'd like you to try this test, but it may take a few days.
