I'm not totally sure what your asking, does your backlights work or do they not?...you said backlights not working but you can see the LED's, the backlights are the LED lights, or are you calling the LCD diodes in the panel the LED' backlights?

If there is a power issue, will a faint light come on at power button and then get blue screen?

Hi, You will have to take the back off and look at the main power board. Make sure the plug is out when you do this. Look at the capacitors. If you are not teck savy get help.
When cost of parts ar more than a new TV then go buy a new TV.
Good luck.

Suddenly no picture only a black screen.The tv has power the little vizio turns on white i can hear the audio and change through the cable channels with my comcast remote.The vizio remote will turn the tv...

Look through the ventilation slits at the back of the TV with the room lights out. If you do not see white light light bleeding through the back, you have a back light failure. It could be the inverter circuit which lights up the CCFL ( cold cathode fluorescent lamp ). You will need professional help to replace it and could cost you about 70 to 100 $ to fix.
