If the tuner is bad, changing the mainboard should fix the problem.

The tv had blue screen briefly showing "no signal" then turns off. ... and I am getting the same blue screen-no signal.


If your television is displaying a blue screen or no signal message and then turning off, your TV may be at an inactive input. Here's how you can get back to watching your TV:
1. Powering on your TV and press the INPUT button on the VIZIO remote control repeatedly until a picture re-appears.
2. If this does not work, try again but press the button slower this time.

I got this off the vizio website.

''no signal'' message on blue screen after watching for 10-30 min


First try another signal input like a DVD player or other source, is the signal displayed ok? Then you have lost the signal on one input from whatever the device is.

Unfortunatley you can not get replacement parts for Vizio TV's. If purchased from Costco and you still have the receipt. then try and bring it back.

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
