Multiple vertical Red lines on my display
Hi, I had given my father a 27" imac for his birthday a few years ago. After his hard drive failed and was replaced, a few weeks later he started on a hard start up to get red banding on the display.
I have attached a picture below. Any thoughts? Does anyone think I need to open up and re-set the ribbons for any drivers or replace the LED driver?
Is dit een goede vraag?
