XVT323SV No HDMI,No WIFI, No bluetooth address

[Grengadgy]

I'm new here but need some help. my vizio XVT323SV cut off today (flashing reboot thingy). It shows NoBluetooth address, wireless doesn't work and on setup it won't show any HDMI inputs(only shows antenna, AV and RBG). It won't show any devices(Kind or brand). I can only use coax, av and maybe rbg inputs. I can use VIA on ethernet cable but can't use NETFLIX or AMAZON
(they are pre-programmed). Crackle works when I download it from the App Store. I can watch DISH and locals on antenna input. On setup lt only shows Antenna/cable, av and rbg lnputs. I haven't taken any voltage readings because to me it looks like it lost memory/programming. I tried factory and hard resets

Any ideas? Thanks for any thoughts. All of this happened after a flashing reboot .

Maybe flashing reboot was a bad usage of words. I wasn't trying to flash the memory rather Vizio was doing it's daily restart. This time
it didn't restart right.

Would taking voltage reading help or simply replace a card. If so which card, maincard? Thanks

No thoughts? Does all of these problems point to the main board? It has a great picture on antenna but I can't use my hdmi inputs and no wifi is found.

Has anybody ever seen problems similar to this on any Vizio?

Seen issues on other smart TVs, it's generally caused by corrupted firmware. The TV might allow you to update via USB, but it's risky as trying to update corrupted firmware could cause further issues.

Thanks for the reply. I have seen instructions on flashing the firmware via pendrive but have been unable to find any firmware. Replacing the main board would probably fix this problem?

Yes replacing the main board should fix the issue. But Vizio main boards are expensive, because they fail so often.

Please start a new thread, put the make, model, symptom in the Title, and up load good clear pictures of the boards and the whole back side of the TV showing all the boards.
