How hard is it to change it
No output from Supply, check fuse, ok. Where can I get a new power supply? Set is 2 years old.

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

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

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.
