Update: Flashing the TV with the Kogan firmware as per the instructions on the linked page worked perfectly. Now when it starts up, the Kogan logo is displayed instead of the JVC logo, but otherwise it is identical (minus the errors).
Of course, if I’d known that this was a rebranded Kogan TV, and not a JVC, I’d never have purchased it in the first place. But at least now it works properly.
About a year and a half ago, I bought my TV through Nuworld, organised by a neighbour who said he could get me a good price. (It was around R9000.) It was a huge mistake. I’ve had endless problems with the TV, that neighbour is long gone, and Nuworld are not helpful. I assume they know this TV has issues, as it isn’t difficult to find others online with identical problems.
It started with the TV freezing occasionally. Then it progressed to Android error messages being displayed modally on top of the screen, with helpful text such as “Unfortunately YouTube has stopped working” or “Unfortunately android.core.process has stopped working”. Hundreds of fucking error messages. But that isn’t even important anymore because now, most of the time the TV stops responding completely and I can’t even dismiss a single error message. Before it got to this point, it would restart all by itself, sometimes in a loop, and sometimes freeze on the startup screen.
It turns out that this is a rebranded Kogan TV. Tomorrow I’ll try flashing the TV with the firmware I found on this page. I need to buy a smaller USB drive first, one that I can format with FAT32, but I’m hoping it will work.
Nuworld “repaired” the TV twice while it was still under guarantee, so I’m assuming that all they did was flash it. This TV is junk. Don’t buy this model under any circumstances. But at least if flashing it works temporarily, I’ll keep the small drive with the TV firmware on it (and I can leave it in USB port 1 since I don’t normally use that port) and reflash the piece of shit every now and then.
I’ll update this post with the result, but I do have a strong feeling this will work. Otherwise I have one hell of a paperweight.
