Could my pixel line problem (TAB ERROR) on iMac 27" get worse?
Good evening you all. I bought an used iMac 5k 27” 2017 and when I booted it up I noticed a vertical line of cyan pixels. At first it was appearing occasionally but then, as I touched the screen near the line, it became kind of permanent.
I read online (especially in this forum) that it probably is a TAB ERROR in which a ribbon connector or something similar is damaged, probably due to a screen opening attempt.
The seller claims he didn’t know about that (lying ofc) but offered me the iMac for half the price (400 €).
Finally, my question is:
The line for 400 € doesn’t bother me, but could the thing get worse? Do you guys have any experience?
Thank you, Raffaello
