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
connected.

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

My 42 Inch Vizio experienced the pop of death out-of warranty. I bought mine at Sears and they sent a technician over within a day or so. It turned out to be in the power supply and they shipped a board right out. Total including parts and labor was $280. Although no expensive TV should die after less than 2-years, Sears seems to be able to deal with repair in the home without drama.

SOURCE: i have picture but no sound on my 42 inch vizio

If you received a remanufactured board it might be defective,Or did you forget to hook back up the speakers? Sounds dumb but happens alot. Speaker wires get in the way,we disconnect them to look at a board or replace one.Often gets over looked.But I have received several defective boards.Hope this helps. Toddthetvmd

I have a 42" Vizio


Your power supply is dead.
Power supplies can be purchased online for a couple hundred bucks, and replacement is fairly simple and requires only a screwdriver.
For those less tech-savvy, you may want to start saving for a new TV.
