Only power button, volume buttons, and touch screen work.

Only the power button, volume buttons, and touch screen work on my Steam deck. Furthermore, there is no longer a chime on startup. This was after I installed a shell replacement. In the past I have successfully completed an SSD replacement as well but I have had no issues until after completing the shell replacement and turning on my Steam Deck. I have gone and double checked all of the ribbon cable connections but still no luck. The Steam Deck still turns on and I can navigate on it with the touch screen or by using an external keyboard. Is there a specific cable that could be causing these issue? Could it be that the trackpad no longer works as I heard that the trackpad is what makes the chime noise? Thank you.
