Their may be a delay of a few minutes between each request for info from you whilst I gather information and write out my text thanks for your patience!

Can you connect another HDMI product into the set just to confirm once and for all that the HDMI on the set is inoperative?

Hi

Please just make sure in the settings menus that their isnt an option to switch on the hdmi some sets have this built into the software

If not its either the hdmi socket itself in that case or theirs a problem with the processor on that board if I can locate a board for you do you think you will be able to fit it?
I will need the part number found on the board (mainboard)the one with the hdmi socket on, it will be etched on the board or on a sticky label?
If not a tech would charge about $300 for doing this repair
