Question about Televison & Video
Friend gave me this tv for free because it wont turn on. said it was working just fine, then quit all of a sudden. when the power button is pressed on the remote, the vizio logo turns from amber to white, the tv clicks, and nothing else happens. im hoping its a simple and not to expensive fix because this tv is much nicer than the one i have been staring at for many years! help!!
Old messages and bcipollina is gonna get to read this resonse twice; sorry-
If it just fails to turn on or ignores the remote, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.
Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.
BTW, from what I have read about Vizio, I think they are close relatives to iLo which was also sold by Wal-Mart.
Quality control anyone?

there a problem on power side.. chage the ic and the resistor going to ic and check also the signal diode.

The main board has failed. Replace the main board will fix the problem.
By the way, where did you buy the TV? If you have bought it from Costco then try to give them a call to see if it still under warranty.
Hope this will help.
