Green/Red Focus Box Missing and Flicker/Flash on LCD

[mut]

Greetings:

1) I recently reset my T3i and can't figure out why the center focus box that turns green or red isn't performing as it used to. When I depress the shutter button for AF the box is there but doesn't turn green or red. It also used to stay on the LCD as green as I took the picture which isn't anylonger as well.

What happens now is it does its focus thing without turning colors and then snaps.

2) Also, all info on the screen disappears when I snap. All info meaning the grid I have up, the focus box and all other info ie. histogram and settings that are on the left side of the LCD. If I recall correctly, all info stayed on screen including the focus box green or red.

3) Lastly, the focus box will flash green when I snap the shot but that only happens "sometimes" and not always.

4) One other thing I noticed too is as I depress the shutter button or snap the shot I get a pink flicker on the LCD which wasn't happening before.

Any ideas how to fix these issues?

Thanks in advance.

Thanks Scotty but it's not that...I wish it was. In autofocus mode the box doesn't change colors. The superimposed display disappears too...something else is going on.

It's not the card or battery nor dirty connectors or seating the lens...all done and nothing changed.

One step given to me such as updating/reinstalling firmware might do the trick hopefully.  It seems to be a software display issue. Possibly electonics...hopefully not.

Thanks for helping.

Firmware update is pretty straightforward and the whole process will take less that 10 minutes.

Find a friend or neighbor who would allow you to use the computer for a very short moment and you are done. And you will know if it is the firmware that could change the problem. Why hesitate.

Please note that the latest version of FW for your T3i/600D is V1.0.2. Mac and Windows have different files.

yeah it's on the FW ver. I'll reinstall and wish for the best.

thanks.
