Hi,
I have a 43HAK6150U H and after an alert came up for a system update, which I did, my tv is now stuck in a bootloop. It shows the Hitachi logo, Android text screen, black screen, then goes back to Hitachi. If I unplug all connections from the TV it will show the home screen for like 3 seconds then go back to the Hitachi bit. The 3 things I have tried so far are the soft reset (hold down power while unplugged, plug back in), a hard reset for Sony TVs that I hoped would work (hold down power while plugging in TV) and just cooling the TV down in case it was the heat as we are in the middle of a heat wave in the UK.
I can't seem to find much information on this TV online, so I'm not sure it's a particularly popular model, but I was hoping someone here may have a solution I haven't tried while I try to get in touch with the place I bought it from.
Cheers for any help.
Update: Argos sent me the firmware as well as instruction on how to use it, which I have put in a google drive here: https://drive.google.com/folderview?id=1v-qbpoxlSHgPPyByvgiL5KnDhz9IshTy
Just in case anyone has the same TV and finds this post googling for a solution, it worked for me :)
Maybe this works:
Additionally, how do I reset my Hitachi TV without remote? Method 2
Turn the TV off. Press and hold the {INPUT} button on the TV then press {POWER}. Hold both buttons until the TV powers on with the Service Menu displayed. Use the {UP} {DOWN} buttons to select items. Use the {LEFT} {RIGHT} to change the data. Press the {EXIT} button to exit the Service Menu.
