Hi there, i am in desparate need of help for my tcl 75c4us tv. It has just stopped working and only turns on as far as the logo screen. I am sure i need a firware update as far as i have been told but i cant find a place to download it for my model. Can anyone tell me where i can download this system update or even the roku number so i can try to get it from the usa tcl site. Prefer the system update file though. But would also be happy if anyone knows the roku number
You may want to get someone who also owns a working similar model TV to pull the firmware out but this requires specialised equipment. Alternatively, some repairers out there collects these firmwares too. But its like looking for a needle in a haystack. Last resort is to change the mainboard. Try searching on Amazon or Ebay.
