If anyone will know this issue it's you lovely people.
I bought this TV used and I think someone has the wrong firmware region of firmware on it? Is that possible?
It's the North American version. T-HKMFAKUC. But it shows version 1218.8 on it and through looking on here, the NA version didn't have a 1218 firmware?
I'm finding the menus freezing seemingly randomly. Some screens I can get too and it'll stay there forever while others will jam up. I managed to get into the service menu and do a factory reset. The resulting initial setup worked perfectly and I thought I had it fixed only to have things jam up again.
And I'm not getting picture from the HDMI's. The apps partially work.
I was trying to find a way to update firmware via USB outside of the menu within the TV [which I can't get to without it freezing before I get there] but I can't seem to find a way.
Any help would be greatly appreciated! Thanks.
How to help? No idea as you already did factory reset. I also do not know any method how to force firmware installation w/o navigating via menus. Migh emmc jtag is an option, but for this some soldering and specific knowledge/skills are required.
