Graphical glitches on 2016 12" MacBook - Display Ribbon Cable?

Good evening all, was hoping someone may have insight for me regarding these graphical glitches/artifacts present on the display of this Early 2016 12" MacBook (A1534). A series of vertical and horizontal lines are present on the display, which kind of "bounce" or move around constantly (not static). If I find just the right angle for the display, all the glitches disappear and the screen appears normal, but will immediately return if the screen is adjusted. The glitches are also much more prominent when displaying colors v.s. hardly noticeable over white backgrounds.

Intuitively, I feel like this is the display ribbon cable being damaged and feel like the LCD panel and electronics are ok, but wanted to know if there are any other likely causes of this issue I should check for before I try ordering a cable. I was given the computer for free because of this issue, and I feel as though it's worth a 20 dollar ribbon cable if that's all that's damaged. However, I don't want to invest much more than a cable because the battery isn't in great health (and who knows how much longer the butterfly keyboard will work right on this 8 year old machine). I know the MacBook Pros of this era had ribbon cable issues, but haven't heard much about the regular MacBooks having this problem, so I'm skeptical and concerned it could also be a logic board or lcd controller board problem. So, if anyone's seen this kind of issue before with a 12" MacBook and has advice, please let me know! Thank you!
