So a few weeks ago my tv got white vertical streak on it, now it’s gone completely black. I have a Phillips Roku tv, I’ve had it for about two years. Any suggestions?
If you can see a picture when you shine a bright light on it, I suggest you research how to repair the backlight unless that white streak is still visible. If it is, it's probably a lost cause. I doubt it's still under warranty, so Philips won't help you and it's not Roku's responsibility since Philips made the TV.
