I've had my 65" hisense roku tv since feb 2020. About a week ago I turned it on, and the hisense roku screen came on for a couple of seconds, then black screen for several seconds. This keeps repeating.
After many web searches I reset with the button on the back, I long pressed the power button while plugged out, I tried a different outlet, I changed the remote batteries, etc etc.
I came to the conclusion that it needs a firmware update because it is in a boot loop
After 3 attempts on hold to hisense totalling over 2.5 hours, I finally got through to someone, who went through a generic troubleshoot, then told me it was a roku issue. I contacted roku customer service, who did the same types of troubleshoots, then told me it was a hisense issue.
I called hisense again and told them that roku insists it is a hisense issue, and the rude agent argued with me for a while, then finally said my tv is too old for them to help me with anyway as it is out of warranty.
I called roku again, and they explained that any roku firmware needs to be loaded via an on screen menu, and, as my tv will not stay on long enough to get there in the first place, it is a hisense hardware issue.
In the meantime, hisense replied to my many emails telling me that it is a roku operating system, so roku need to fix it.
I got on to roku live chat and explained all of this and the agent told me to contact hisense.
So, my tv loops from home screen to black, and back again, and my customer care questions keep looping from hisense to roku and back again.
The only conclusion so far is that neither roku nor hisense back up their televisions enough to ever trust either of them again, and I seem to be stuck with a nonfunctioning tv that neither will help with.
Has anyone been lucky enough to get further down this rabbit hole to a solution or have any more ideas on where to go next?
If anyone has read this far, thanks for that at least anyway!!
