Re: board power up failure
Well the say never answer a question with a question, so i will simply post 2 answers.
1. If you built the PC yourself, you may need to look at power requirements for this particular motherboard and perhaps transplant the board into a case with a larger power supply. (ie: 300, 350 watt power supply or better )
2. If this is an older PC and someone else built it for you, you may need to consider that power supply units do burn out in time and may need to be replaced.
The power LED simply means there is power coming to the light itself, but may not be enough to sustain an entire motherboard and components etc. This to me sounds very much like either the power supply is too small or burned out.

Is the standby led on the front lit. If not likely the problem is with power supply. If the standby led is on does it go off when the power button is pressed? Does the led blink. If so count the blinks and get back. The power supply provides an standby voltage to the main board. If the standby led is lit then this voltage is present. When the power button is pressed the micro sends a turn on voltage to the power board. Normally the power supply will respond and all other voltages needed to operate the set will come up. if a component is shorted the micro will not turn on the power board and will usually give a failure code via the standby led.
does the vizio logo light up orange ? If so and it doesnt turn white then the main board would be suspect. If the logo doesnt turn orange when its pluuged in then its the power board. You can get either board from www.tvrepairworld.com
Hi Franceso, plz specify Is it powering ON ? Which LED is glowing? These leds are there on the front panel :
1 Power On/Standby button 2 System power LED Green = Power on Amber = System shut down, but power still applied Off = No power
3 Internal health LED (Wave sign in BOX) Green = Normal Amber = System degraded. To identify the component in a degraded state, refer to system board LEDs. Red = System critical. To identify the component in a critical state, refer to system board LEDs. Off = Normal (when in standby mode)
4 External health LED (power supply) Green = Normal Amber = Power redundancy failure Red = Critical power supply failure 5 NIC 1 activity LED Green = Network link Flashing = Network link and activity Off = No link to network. 6 UID LED Blue = Activated Flashing = System remotely managed Off = Deactivated 7 UID button
If it is Internal health led then any internal h/w issue is suspected. If it is external health led then any power supply or power source related issue is suspected. Also
