Default Vizio m3d650sv strange power-on issue

Its at firmware revision: 2.17.0.1100
Plugged in the LAN cable and only apps updated. Apparently there is a newer firmware.

Anyway, at odd times if I have the power cable unplugged, the TV will get stuck on the vizio logo. It doesn't seem like it happens when its powered on but did do it once plugged in.

I hafto unplug it and plug it back in for it to get past the vizio logo sometimes.


Any advice? There's no reset button, a few caps looked bulged but not leaking on the main board.

Any way I can get it to update its firmware?

Update: I powered it off and now it won't even power on. The vizio light is just amber.

If you have any freeze spray, (or use caned air duster upside down) and with the tv UNPLUGGED, freeze the eeprom ic on the main board, wait about 10 seconds, plug the tv IN and try turning it on, if this works the eeprom ic is giving the problem.
