Problem with white screen and vertical lines after USB-C mod and Cap

This was a working SP. I wanted to install a USB-C mod for a more modern charger. After installing it, the screen displays only lines. The sounds and buttons work normally, so the game is running but now video. I removed the mod and it worked again. I did this twice before I realized that it would not work with the new hardware installed, but worked fine without it. I eventually removed the usb-c for good and thought it might be a good idea to change the cap for good measure. It is now doing the same thing it did with the usb-c mod. I have obviously have a failing component that is getting stressed by these additions, but I cant figure out what. I have another SP and checked the screen to make sure it was not that. It displays the same lines with the second screen. The usb-c mod is off at the moment, but I cant put the old cap back on since you practically have to destroy them to remove them. I'm at a loss. Can someone give me some ideas as to where I might start looking? Thanks

Here is the result.
