Recently upgraded from a 3092 to 044 boards. After installing backplane with no problems, I noticed that the MPU won't slide in all the way. When booting up I get the expected amber and 2 green led's, but get 'No Input' on the screen, so it's obviously not making the complete connection. One time I was able to get the MPU in far enough and things booted up as expected, got video, was able to run through keychip options, play a game etc. But overnight the MPU slid back out just a tiny bit and lost the video and functionality, and I can't recreate that perfect depth/connection again.
I was recommended to try taking out the plastic guiding piece at the end of the MPU as well as the screw on the backplane it's self, and neither helped. It just seems to get down towards the end, and almost springs back towards me. I have checked the pins multiple times at the connection point, nothing obvious sticking out on the backplane, and nothing on the tray itself would seem to stop it. The guide track on the left side does have a bit of a curve (see pic attached) but not sure if that would cause it. the 3092 tray slid in and out with no problems.
Attached are pics of the MPU as far in as I can get it, as well as the backplane and bent track.
Any insight would be much appreciated!
