My right eye screen is glitching. The screen has a vertical offset, many distorted pixels, it doesn’t happen on all screens during the startup of a game, I did try out several games). It has only been doing this very recently (2019), so I’m in doubt if it’s really the degradation of the flat cable connection (through glue). In it’s 23 year lifespan, that’s quite sudden/seems late? A student of mine inserted a cartridge with the cap still on. Luckily I was able to remove the black cap from the slot, but I wonder if it could be one or more of the pins that plug into the cartridge are not fully connecting that will cause the glitch?
