I've had the issue shown in this video for probably last couple years:

Applying pressure to that side of the screen has often fixed it for hours at a time so I've never taken additional steps to have it fixed.
Seems like it might be an issue with the cable/s going from the DP board on that side to the TCON. I have tried re-seating the connector into the the TCON on numerous occasions but with varying results (sometimes fixed for a while sometimes not).
If the cables are damaged am I able to get replacements?
Thanks.
