Just purchased a Hisense 70" roku tv less than 2 months ago after our first TCL roku tv turned off and never came back on (had for less than a year). Turned it on today and everything was fine until we tried using the playstation or streaming channels then the screen would dim to almost black. Messed with the settings and used some suggestions from google, but nothing really helped. Anybody have any other suggestions? We've moved cables and wires, moved the plugs around, still nothing.
This is beginning to become a complete waste of money and I gave roku a second chance but if it's something that can't be fixed, I will not waste my money again. Too much of a hassle for someone living paycheck to paycheck.
I just bought a brand new Hisense 58" Roku 4K Tv. Its only been 3 weeks, this morning I got the Dark Screen Problem also. It had been working fine all this time. I changed settings.. it only worked on Movie Mode in Picture Settings.. but i cant use that because the coloring is different .. as im using it with my computer as a giant monitor.
2 bottom HDMI ports are doing the dark issue but the top HDMI port works normal?
My Roku Menus work normal though.. its only when i select an hdmi port it goes dark. I changed everything out.. Same issue. Seems to be the Operating System Roku..
Tonight when I turned on my Hisense 58R6E1 TV the Roku menu was full brightness, but when I select anything to watch (cable TV, any streaming app, the DVD player, etc), all picture modes except "Movie" result in a dark screen. Bought it a little over a month ago at WalMart. Guess it's going back tomorrow!
This literally just happened to me. I bought a 70" hisense roku TV a couple of months ago. Thankfully I bought this POS from Costco. It's going back next weekend when I have some time. First and last time I buy hisense/roku.
Just experienced very similar issues. The screen isn’t necessarily going dark, the colors are inverted. I solved it by unplugged the power cable for 30 seconds and plugging it back in. Works fine again
