Re: 42 vizio power supply

The power board is very easy to replace, but from my experience it seldom goes bad on these sets.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

SOURCE: Standby power usage of the 42" Vizio Gallevia?

According to a Cnet review of the 42" Vizio Gallevia, the standby power usage is only .75 watts. Because it is so low, I now have no concern about leaving the set in standby mode. Virtually no savings to be realized by unplugging the set between usage.

Vizio vw42lhdtv10a 42" vizio will not turn on the vizio light is orange when tv not on and white when tv is on it turns white but i get no video or audio the screen doesnt change like it even wants to come...

check out the power supply board! Look for popped capacitors. They either leak or swell up. They are the can shaped things on the board with the plastic coverings on can usually see a swollen cap sticking up over its covering as a telltale sign.

Good luck and be careful
