Have TV Questions? Ask a TV Technician
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
There should be an onboard button, either on the right hand side of the tv or the back/bottom edge, that will let you power on/off manually, and you may have an input button there as well to disable the sleep mode.
If you can tell me the full model number of the tv, I can help you find a suitable replacement remote, though there is a possibility there is some other underlying hardware fault here.
