Hello,
Thanks for allowing us to help you. Many issues as your present a issue with the power supply board fuse inside the tv, other components effected.
Have you tried unplugging the unit from the outlet and plug it back in?
If so the issue is within the power supply inside the tv witch would need repair. There is no quick fix to these types of issues that are presented.
so you have some options:
1. new TV
2. DIY repair
3. Expert repair
they all cost more then this email today witch was FREE at this point. I hope this information was very helpful.
Btw, I’m available to help over the phone in case u need at
