Facing TV Problems? Ask a TV Technician.
Hi , I`m Jack Perhaps I can help you with this problem , let me know when you`re ready ?Also , could you please give me the tv`s model number ?
Sorry Calvin , had to step out for a bit .
So you are saying that it is asking for a 4 digits code but even if you enter the default 0000 it will not take it ?
Or have you tried any digits yet ?
Can you see the tv`s normal menu or the tv is stuck on that screen ?
O.k then it looks like your tv`s processor is locked somehow , i believe your dog did a good one .
Try this ; Unplug the TV's power cord and hold the power button directly on the tv ,keep holding it for 20 secs or so then let the tv sit unplugged for a couple of minutes before you try it again.
O.k then there are no known procedure to get out of this beside what i just gave you .
By the look of it the main board`s eeprom got corrupted (common for these vizio) and a main board replacement would be the only thing.
You could try to unplug the power for an extended period like overnight or 12 hours + but i don`t give this much chance .
Then you could look at the link below and match your main board with one of those versions ;
