Question HISense TV going dark after a minute

[hyankov]

I have an issue with a 55h8g TV. I will preface this by saying I am tech-savvy. Need help from someone who is familiar with the technical details of the following issue.

After I turn the TV on, it goes "dark" in about 1min of uptime. None of the changes I make to the TV seem to persist - adding/removing accounts, soft resetting (erase settings), etc. Before this happened, I've had a prolonged period of time where I was getting "out of storage" warnings. I disabled some apps and removed others. Not sure if that's what bricked it. It's currently unusable.

Using the serial number, I've downloaded the latest firmware and put it on a FAT32-formatted USB drive. I am trying to reset/update the firmware, but none of my methods work - especially powering it on with the Power button pressed, does nothing for me. Once booted, if I manage to get to the firmware upgrade on the menu, I see a choice: Reboot or Cancel. When I reboot, it does nothing.

Any advice?

PS
I am never buying another HISense TV.

How long have you owned this TV?

For a while, it's been acting up about storage for a long while, but bricked in the last 1 week

I doubt a firmware update will change anything. Sounds like a hardware failure. Those really aren't too serviceable.

I am leaning towards replacing the motherboard now ...

If you can find the right one, that might help. With the relative lost cost of 4k TVs, you need to account for how much time and money to sink into this one.

I am getting it for $73 shipped, so I think it's about fair. I'm not looking forward to dismounting the TV from the wall and then back on, than replacing the board itself.

Good luck. Please follow up with the results.
