Facing TV Problems? Ask a TV Technician.
Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. In order to assist you, I need to ask for more info.
1) How old is the set (roughly) and when did the issue occur? Were there any storms, power outages, etc.?
2) When you press the power button, does the red light blink- or does the screen light up- even for a second?

Thanks for the reply. This does indicate a hardware failure in the TV- more specifically the Mainboard has failed and needs to be replaced. There are no pushbutton fixes for this. That said, the Mainboard is a "plug and play" part- meaning no soldering or special tools are needed to replace it. Are you looking to repair this yourself?
I am searching for one in stock now.
Yes, the HDMI port failing initially is what clues us to the Mainboard having failed.
The part is available and in stock at the link below for $180:
All of the screws on the back of the TV must be removed, then the back of the set pulled off. The Mainboard is the one that the AV and HDMI ports directly connect to. There are plug in wire connections that must be removed and then several screws around the edges of the board to remove it from the set. Installation is the reverse of removal.
