The word ''no sync detected' means that there is no video connection between the cable box and the TV set. Isolate the source of trouble by connecting to the TV a prevoius video source that worked properly e.g DVD player. You should also try to get a new set of video cables as the ones you have may be internally broken.
Please follow the installation instructions carefully especially the colour codes of the video and audio cables i.e yellow cable to yellow connectors of TV and cable box , Red cable to red connectors of TV and cable box etc.
good luck!

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.

FOR COMCAST

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

2. Press MENU on COMCAST REMOTE.

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

How many months or years of your monitor that you are using? Do you check the outlet, cables? It's seems that your monitor has a problem because i read your observation that your monitor seems to be replace a new one. That's the monitor's problem.

Screen is all Green


New cable box recently? If not, your cable provider has probably pushed a firmware update to your cable box. Green screens are very common with HDMI connection. From your symptom, I am going to take a guess that you are connected via HDMI. If so, switch to Component cables and your problem is solved. It's not the TVs fault... cable boxes seem to be the single largest problem child for HDMI compatibility. I hope this was of some assistance.

JVC GR-X5e camcorder, lens cap message. Does not show a picture.


It shows all menus, numbers and graphics on LCD, but seems like there's no picture coming through the lens. In both modes, video and still. It seems like it can not see anything as if the lens cap was on all the time.

Could this be a problem with sensor.. CCDs? Lens? Something else?

Cannot set screen width


Both the TV and the Cable box have Aspect(height/width) settings. You must confirme the setting on the cable box and then do the TV.

1. Set TV to Native, this should show image exactly as the cable box sends it.
2. change Aspect settings on the cable box until you get one that works
3. if you get a good one, then your OK. You will just need to find a setting between the 2 devices that work for you. Also, these settings may change automatically for the TV or cable box based on the channel

Loss Sync


According to SharpUSA the problem with the "Loss of Sync" error message is that (most probably) the cables (between the box and the display) are not connected properly (so remove and reconnect them carefully, on both units) or a cable is defective. 

Also, after you reconnect the cables try turning on the unit, if no success then depress the "clear" button on the external box (under the door on the front and on the bottom left and try turning on the TV again). 

It is, most likely, that the cables are not seated properly. Reseat the cables on both the display and the external box. 

Hopefully, this will clear the problem
if still does not solves your problem just replace all the cables connected between .u can get the new cables at radioshack web site.just place an order they will provide you. thanks.
