SOURCE: vizio 42" fhdtv - need help for better picture quality settings

Since you're using "analog cable", I would adjust the television such that the picture is not streched. This means there will be black bars to the left/right of the 4:3 picture, but you should experience some improvement in picture quality because the TV is not trying to interpolate what to do with an already crappy analog cable signal.

You may also want to add a signal booster where the cable first enters your residence... often, folks split that analog signal up so much it is weak... and looks much like you describe.

TV has no picture, no sound just the VIZIO logo light is on the screen.


Did you check out the power supply for proper operation since both the audio and video are gone? If PS is good then the problem may very well be on main board.

Getting no audio from speakers on a Vizio E421VA LCD HDTV, any ideas?


Do headphones work?
my guess is either the headphone socket or associated wiring/soldering is faulty or there is a faulty connector within (connector associated with the audio)

Vizio e421va picture going black


POSSIBLY T-con pcb, but check the cables between the T-con & the panel & the cables between the t-con & main pcb.
Try unplugging & reconnecting those same cable links. When disconnected look at the condition of the cables & boards. your looking for signs of arcing or corrosion.
