I was on the phone with them for 37 minutes and the person I spoke with had me hold Control, Option and Shift for 7 seconds and then press the power button and hold all 4 keys for 7 seconds. That didn't work so I immediately called Apple. I turned my computer off and restarted a couple of times because that is always the first advice one is given with computers. Yesterday, I came back to my desk after lunch and the Macbook Air that I purchased in January of 2021 had thin horizontal lines across the entire screen top to bottom. This is usually a ribbon cable that leads from the LCD to the main video board that for whatever reason has unseated some of its contacts.if you feel brave enough and think it's worth reseating the cable.make sure it's switched off from the mains.put the tv face down on a duvet or bed.remove all the rear screws and spcables and prise of rear panel.look for the main cable that comes from the LCD and trace where it connected to the video board.disconnect one end at a time and check for oxidation on the contacts.and reseat.thus usually cures thus type of problem.if it doesn't then the next likely area of cause will be the video board itself.these are modular and you can either source the exact board from eBay or source a broken screen version if the same tv.and use it for chance your arm and get a quote from a tv repairer or bite the bullet and by another set.I know some the answers are pretty obvious.but I am sure you will gain more of an idea from what's been said.
Although this might seem strange I read somewhere that if there is a loose connection along the LCD connectors applying pressure might confirm this is the lines change with the application of pressure. I have attached two pictures below which I hope go some way to demonstrating the issue.ġ: Switched the TV off for a period of time and then switched it back on - The lines still appear.Ģ: Removed all the connecting cables (Amazon, HDMI, Cable) and then switched it back on again - The lines still appear.ģ: Conducted a factory reset - The lines still appear.Ĥ: Applied pressure along the edges of the TV where the lines appear - No change, the lines are still visible, no distortion to them. They intermittently flicker between 1/3 of the screen having visible lines to only the top three of four lines. Only yesterday a number of horizontal lines appeared on my TV screen, only the lower 1/3 portion of the screen though. Hi all - Hopefully someone out there might be a little bit more helpful than the Sony Troubleshooting Guide:
