Hello and sorry you're having problems. Please elaborate on the following: 1) How long have you owned the set for and when did the problem occur? 2) What do you mean by "goes Dimm"? Do you mean the screen gets dark but you can still see an image?
Customer: replied 2 years ago.
No the letters that said Vizio,we turn the set On and the Vizio goes bright for a few seconds and you can the hear in the power supply a noise that the est is trying to go,but shuts down,I a Technician tryin to repair this set for a customer,after a few seconds the Vizio logo goes dark, no back light.-

Do you have a meter- yes or no please?
Customer: replied 2 years ago.

Okay, and then it drops out- backlight goes out, etc. correct?
Customer: replied 2 years ago.
is not back light any time.-
Expert:  Aric replied 2 years ago.
Oh, so the Vizio Welcome Screen never hows up- you were talking about the power light? Sounded like you meant the screen shows the Vizio logo.
Expert:  Aric replied 2 years ago.
When you said- "at turn ON the Vizio comes OK for a few seconds and goes Dimm"
Customer: replied 2 years ago.
no,is the power light indicator,repeat, not back light any time.-
Expert:  Aric replied 2 years ago.
Gotcha.
Expert:  Aric replied 2 years ago.
In this case since you get 12 volts for a fraction of a second, then drops back down- with no backlights (LED drivers aren't engaging), then you would need to replace the power board to fix this issue. The board can be purchased at the link below for $45 and change to fix the set. Average repair cost is in the $200-$225 range (parts and labor): http://www.shopjimmy.com/vizio-56-04263-121-power-supply-unit.htm If you need further assistance let me know.
