A vertical white stripe has appeared on the left side of my screen

SOURCE: Red Stripe, right side

Follow-up. I found the slip on which the LG tech wrote down the part number for the board to fix the vertical red stripe. I was mistaken in my previous post. It was not the Z-Drive board. The board you want is:

X DRIVE BOARD; Part 6871QRH043A
Type in the part number in a search engine and yuo will find multiple places to purchase. Ebay may be the cheapest. That's where I got another part which got my picture back. I did not buy this part myself because now that I have my picture back, I do not want to screw it up, so I live with the red stripe.
