M17x R4 Plugged in HDMI input now screen flickers nonstop

Yesterday, I decided to dust off my Raspberry Pi that I bought several months back and connect it to the computer.  I didnt really stop any of the running programs or anything, just left everything as is and connected the HDMI cable.  Right away my Raspberry Pi screen popped up with no flickering.  (which means it's not the LCD screen I believe)

The Raspberry Pi doesnt have an "off" button.  You "shut it down" and unplug it afterwards.  I don't know if the HDMI Input still thinks it's connected or there are NVIDIA driver issues (I read alot of similar problems with regards to that subject)

Basically the screen now flickers.  It does not stop and also flickers if I go on my Linux install.  When I connect an external source to it though, the flickering goes away and I have a clear picture once again.

I know it is not the LCD??? because even afterwards when I connect my Raspberry Pi, the screen works perfectly.

EDIT:

In the end, it turned out to be the LCD connection to the Video Card.  You can see all the info in my last post, basically I toyed with the connection, found the right spot and taped it down with some electrical tape.  It was  difficult, because the right spot was a little loose, not shoved in all the way like one would expect;  I had the issue whenever I would shove it all the way in, but when it was lightly put in, the screen worked completely fine.  Then I taped it in place, not pushed all the way in, but so that it would stay in its place in a relatively loose position.  :)
