I purchased my Samsung 4K TV in July 2018. This vertical band showed up in March 2020. I contacted Samsung and they suggested some simple troubleshooting ideas, which I tried without success. Then then told me that since my TV was past the 1 year warranty, I should take it to a repair shop.
SO DISAPPOINTED with Samsung! I did not purchase the extended warranty from the store where I bought the TV because I thought that Samsung produced QUALITY products, that I would be ok without the extended warranty! Not even TWO YEARS and my $700CAD Samsung 4K TV is toast! I cannot in good conscience ever recommend Samsung TVs to anyone!
Final note: I have not taken it to be repaired yet. I am hoping that taking the back off and cleaning it might correct the issue. Perhaps it's dust, or a dead spider 🕷?
Anyways, I am scared to try and take the back off and clean it for fear I could make the issue worse. If anyone has tips or tricks to do this safely please let me know!!!
UPDATE: today that bar started flashing black noise as well
SHAME ON YOU SAMSUNG!Vertical Bar shows all the time no matter what the watch source is
