Re: Need a solution


Sounds like a tuner or video problem. I have to agree with Comcast, if it were a loss of signal problem, what you would see normally is a blue screen (video mute) and/or more often than not same problem on all channels. Off hand, the only easy user thing you can do would be to do a hard reset, that is unplug the unit from the mains or a couple of hours. If after the hard reset things are still the same, then perhaps your best bet would then be to seek the services of a qualified service technician.

Should you wish to venture a do-it-yourself diagnosis, you need to be comfortable working with electronic components and circuitry, familiarity with a DVM and perhaps even a soldering iron. Diagnosis would relatively be easy since you have 2 other units that you can use as a template for readings. Still you can go through board swapping until you have isolated the defect.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information. Likewise, pls include brand/model of your TV.

Good luck and kind regards.

Lip sync

Vizio HDTV- Lips out of sync

Anyone with a new Vizio E601i-A3 60" or 70" HDTV that is having audio "Lips out of sync problems" with a cable or satellite box.

On Comcast cable boxes (or others), here's what you need to do: FIND MENU for AUDIO or HDMI setup on CABLE BOX or Satellite Box.


1. Turn on TV and have Cable box Turned OFF.


3. Go to AUDIO Setting OR HDMI Setting. (On cable or Sat. BOX)

4. Change setting from Auto to L-PCM. (Turn off cable box to exit)

This should resolve any "out of sync" lips to picture after commercials on HD channels.

*This is a handshaking issue from the cable box to the Vizio E601i-A3

Olevia channel setup

With the remote of dish you will control the dish box. The tv control is only necesary to set the signal on channel 3 or Aux to get the signal from the dish box.

Now Your main remote will be dish remote control. Set your tv on channel 3, then turn on the dish box, and use normally.

Poor picture quality on certain channels only

You could try moving it to the other room to see if the connection is bad. Better than taking to the store just yet. If the picture is still bad at both connections I would just bite the bullet and take it back and exchange it while its free.
Hope this helps and let me know if you need more ideas.
