Samsung QE75Q60RATXXU horizontal lines

[cookie786]

Hi, I have had this tv since before COVID and have slowly noticed there are vertical lines appearing on the left half of the tv. It looks to have been gradual thing as now the lines are showing up on the right side and image quality is being affected, not only that but the lines are so clearly visible now when watching anything with light colours. Does anyone have any idea? 

Apologies for the quality, but you can clearly see in the photos the lines are visible.

Hi @cookie786 

Firstly check that you have the latest firmware on Samsung Support which appears to be 1420. can be updated via USB if not available over the air.  https://www.samsung.com/uk/support/model/QE75Q60RATXXU/ 

However that may not be the issue  ,could try power cycling by unplugging from mains for at least a minute and/or Factory Reset.   Are the lines permanent and on all sources?  If still issues check cables are fine and if so would suggest disconnecting external devices for short period and trying again.  

However if picture Test produces errors suggests there is a fault and would need to contact Samsung for options.  Go to Settings-Support-Self Diagnosis-Picture Test.

Hi @JAMES4578.
Yes, I have tried all of the above and the lines are still present. Doing the picture test resulted in a fail in all 3 tests. I can see the images shown, but the lines are so heavily present.

Oh right, you would need to contact  Samsung as likely needing a repair if viable.
