When I turn my 32" vizio on I get no signal sign. I have my tv connected with 12 ft HDMI to U-Verse Mot cable box. My cable is in the wall and very difficult to replace.

Does this do the same thing on say a DVD player? could be your HDMI cable, your U-verse box & lastly the Main-I/O PCB. I'm thinking the most likely issue is with U-verse.

If you're trying to display output from the laptop to the Vizio you'd be better off using an HDMI to HDMI cable. The VGA port on the Vizio E320 only supports 640x480 resolution; you have to set your display output accordingly, usually in control panel. Using HDMI you're able to keep the signal HD, @720p. The E320 also supports 1080i, but you're not going to see all 1080 lines. If for some reason you're trying to go from the Vizio to the laptop it just doesn't work that way.

Vizio's have an input button on the remote. Be sure to check all of the connections listed. It is important to know how your cable plugs into your TV. I.E. Cable, HDMI, etc. looking at where it is plugged into on the tv will help you to ensure that you have the correct input chosen. Also be sure your cable box is turned on. If it is off or unplugged your vizio TV will not register a connection.

I hope this helps!

first of all just switch off everything then switch off the mains, open the mains socket as there might have been a loose connection to the terminals which you`ve got to tighten. also confifrm that the earthing is well connected before you switch on .
swtch on the mains then switch on your devices one by one, also confirm that the VGA cable is well connected to the display unit

Hello
Check all the signal cables at the backside of your Vizio for firmness. If there is any loose or bad cable connection, especialy with HDMI; will poise this problem. Check the input selection also. If improper input selection is done, there will be no signal logo will fly around.If you have selected TV instead of HDMI, when HDMI is connected and you want to see the programme, is an example of improper signal selection. Check these. OK.

reset the uverse box. try resolution output settings from box. reseat the hdmi with tv and box.

Hello

The HDMI[1] input on your TV receives digital audio

and uncompressed digital video and audio from an

HDMI device or uncompressed digital video from a

DVI[2] device.

This input is designed to accept HDCP[3] program

material in digital form from EIA/CEA-861/861B-

compliant[4] consumer electronic devices (such as a settop

box or DVD player with HDMI or DVI output).

The HDMI input is designed for best performance

with 1080i high-definition video signals, but will also
accept and display 480i, 480p, and 720p signals.

To connect an HDMI device, you will need:

• one HDMI cable (type A connector)

For proper operation, it is recommended that you use

a short HDMI cable. You should not encounter

difficulty if you use an HDMI cable shorter than 16.4

ft (5m).

HDMI cable transfers both video and audio.

Separate analog audio cables are not required (see

illustration below). Some CDVs (video CDs) may

not output digital audio signals. In that case, you

may hear sound by connecting analog audio cables.

However, if you connect analog audio cables with

this connection, the HDMI terminal on the TV will

not receive the HDMI digital audio signal and you
will hear analog audio only.

To ensure that the HDMI or DVI device is reset

properly, it is recommended that you follow

these procedures:

• When turning on your electronic components,

turn on the TV first, and then the HDMI or

DVI device.

• When turning off your electronic components,

turn off the HDMI or DVI device first, and
then the TV.

To connect a DVI device, you will need:

• one HDMI-to-DVI adapter cable

(HDMI type A connector)

For proper operation, the length of an HDMI-to-

DVI adapter cable should not exceed 9.8 ft (3m).

The recommended length is 6.6 ft (2m).
• one pair of standard analog audio cables
OK

Here a way,u could test,if it the cable signal,tv Main tuner board have problem or the DVR box again.U have analog antena?Or go and a buy a digital antena.Reset ur tv to free air signal and use it for few hours,turn it off/on and see if u losing signal,require unplug,replug to get signal back.Two problems solved ur tv board or cable signal good or not?Than U know it the DVR box and have connecting problems.

disconnect hdmi cable and shutdown pc, completely power it off. plug your hdmi cable back in to your pc and power it up. it should properly detect your tv. i use projector mode. tv must stay on while performing this procedure.

when you hook up the cable, what type of connection do you use? if you're using HDMI then try some other connection. Cable box seem to have HDMI connection problem. Also make sure that what ever the input you hook the device to, you have that input selected.
