Vizio half of screen is solid color bars. Top half works great.

Unfortunately, this sounds like a panel issue

All Vizio TVs have their own local power button. It may be behind the screen at either the left or the right side. Look for a strip of plastic buttons and the top button will be identified as "Power" or has a symbol that looks like a "C" sideways facing up with a "I" or a bar inside. That is the international symbol. Pressing it once will power on or off the TV. Watch the VIZIO logo up front. When you power it on, the logo is white. When you power it off, the logo is orange and will dim off later..

Read the user manual for more information, or visit and search the Vizio home site, go to the Support section, and do a search with the model number for a copy of the user manual in a PDF format that you can download.

Does the menu function display the same lines? What kind of cables are using ? (HDMI, Component vid, S-video, co-ax)
Were you as tenacious checking all cables/connections as you were the electronics? Lets rule out this all too often over-looked possibility.
Do you still get the lines with nothing connected to the TV? (no source connected)

Mr. John either one of two things from start u have done right this is a common thing on flat sets hooked to Direct boxes by HDMI having surges come from box to set. The main board usually needs replacing, so either u received a bad board or u have multiple issues and possibly the T-CON board got surged from main board. This board is located above main and power in center at very top of screen. This will cause symptom that u are describing. Hope this helps.

Vizio TV model E371VL turned on ok and had tv show on ch.4.
Turned on the DVD player and put movie dvd in and closed tray.
We have done thhis numerous of times and never had a problem.
This time " HDMI " was showing on top right of black screen,
then " No Signal " came up on screen, then went completely black screen. Called Vizio, they had me power off and unplug set.
Push and Hold power button on TV for 30 sec. to reset.
Replug set and Vizio (lighted) on lower front of set lighted normally dull orange. Pushed power button on remote and when set did not come on, then push main power button on side of TV. Nothing, no White " Vizio " from orange light. Is this a power supply (0500-0412-1020) problem ? Thanks, Sidney ([email protected])

Try manually choosing lower resolutions in your xbox display settings. My Insignia HDTV does that when switching resolutions like on Hulu in between commercials and then back to the show but only for a second or so. Also does this when going from the loading screens to the game screens for a few seconds when playing the game Split/Second

This is a common problem with many LCD monitors. The
printed circuit board that provides a stable voltage for the monitor to operate
from starts to fail. The PCB can be replaced, when/if they are available, or repaired
in most cases at a much lower cost. for more information on this email me at
