Question about Samsung HP-R4252 42 in. Plasma HDTV

Follow up on HDMI Issue

Hello again - actually the problem is NOT fixed. I have isolated the issue and it is the TV, not the receiver or the cable box. When I shut off the TV and turn it back on, it somehow resets the cable box to the old bad settings. I have kept the TV on and shut off either or both of the receiver and the cable box and then back on and each time the setting sticks. I have tried messing around with the TV settings but the only thing I can really do there is choose 4:3 or 16:9. Any thoughts? Thanks.

    Sadly, I have no "Shop Mode" so that did not work. Yes, what is happening is if I go into the cable box menu and change HDMI/Pb whatever to 1080i and the 4:3 override to 480p and exit out, all is FINE (i.e the 4:3 image is being stretched to 16:9) UNTIL I turn off the TV (and only the TV) and turn it back on. Doing that somehow causes the cable box to restore the default settings (780p and 4:3 override "off"). In the TV menu, as noted above, my only real option is to choose eitherr 16:9 or 4:3.

So you can choose 16:9 which is what you want correct? When you choose it on the tv, it resets after turning off correct? or does it have a black bar around the picture?

So if you set both to 16:9, then both change back or just the cable box?

    it may be possible that the type of cable is making the cable box think it should switch, try using a different kind of cable and see if that fixes it

    The below information was found on a forum and I think you may just have this problem, please try this and let me know if this works or if any of the above options works

    Hey I think I have the solution to your problems. I believe you might
    possibly have "Shop Mode" turned on. Here's some info I copied from a
    forum I discovered awhile ago:

    Floor Sales Tip as Promised- Almost every Samsung TV in every
    technology will have a feature called "Shop Mode" . Note- this is not
    turned on at the factory- so it must be done with each TV on your sales
    floor. Shop Mode checks the picture output every 30 minutes, and
    returns all settings to a center or neutral position! Cool-huh? To make
    this happen- simply go the the TV (Not the remote) push and hold the
    "menu" button in for a few seconds- and the words "Shop Mode" will
    appear onscreen- you are now engaged! Holding the menu again will
    defeat this feature.

    I turned on shop mode by mistake when I was holding the side of
    the TV when I was moving it. Possibly the same thing happened to your
    set too. I hope this helps! Good Luck!

    Here's a link to that forum topic I mentioned:

Why does sound turn off.

Follow these steps to troubleshoot if there is no sound or intermittent sound from the speakers.
IMPORTANT: Not all of these features and/or functions are available on all products. Consult the instruction manual that came supplied with your unit to verify if your particular unit has these features, or if more detailed information is required to perform any of the steps below.
NOTES: Click on the appropriate link below if the issue is occurring with a particular device or connection.
  1. Make sure the MUTE function has not been activated.
  2. Try turning up the volume level.
  3. Check that there are no headphones connected.
  4. Try setting the Audio/Video (A/V) receiver to a different Surround Sound mode.IMPORTANT: Verify that the source you are playing is encoded with Surround Sound audio. If not, the audio will be very difficult to hear using a Surround Sound setting. Set Surround Sound to OFF when playing a source that is not encoded with a Surround Sound signal.
  5. Check each speaker to make sure they are properly connected to the A/V receiver.
  6. Perform a Test Tone function to verify if the speakers are working correctly.
  7. Verify all external audio sources are securely connected to the appropriate inputs on the A/V receiver. NOTE: If the audio is being sent from a television to the A/V receiver, then it may be necessary to disable the internal speakers of the TV or set the audio output of the TV to FIXED or VARIABLE. If the audio output of the TV is set to VARIABLE, then you will need to increase the volume level of the TV.
  8. Make sure the correct audio input is selected on the A/V receiver.
  9. Confirm what type of HDMI® devices are connected to the A/V receiver and then check the following:

    1. Test each one of the HDMI inputs on the A/V receiver to confirm that all of the inputs for the A/V receiver are working.
    2. Try a couple of different HDMI cables to verify there is not a bad set of cables.
    3. Unplug the video source from the A/V receiver and connect the source directly to the television. If there is still a problem with the audio, continue to the next step. If connecting the source to the TV corrects the sound issue, service will be needed on the A/V receiver. NOTE: Additional troubleshooting steps are available to troubleshoot instances when the audio, video, or both goes out when using an HDMI connection.
  10. Verify the DEMO (demonstration) mode is not active.
  11. Change the ATT (attenuate) setting. NOTE: The procedure to change the ATT feature varies by model.
  12. Reset the A/V receiver back to factory specifications.
The troubleshooting steps listed above should resolve your issue. If you have completed all of the steps and the issue is not resolved, service may be required.

Give signal to TV with other devices. Feed it the signal from a DVD player, and see whether there is picture and sound. If it is OK; be sure that the problem is with DTV receiver. OK.

If you are using a powerstrip may not be supplying enough power to run the LG HDTV and your HD receiver. If you are using a powerstrip make sure the receiver is plugged directly into the wall. Otherwise this may be a grounding issue please reply if this doesn't work and we can look into some other possibilities.

Hooked up our Vizio to dish network. but have had a problem with buffering. The picture will freeze and then start up again. The HD Movies would have the lips moving out of sync, I have went into the audio...

Hello, there are a few things that could be causing this. Usually when this is happening, we have you unplug the receiver from the outlet for about 10 seconds, so if you have not done that yet, go ahead and do so. The receiver will sometimes do that, and it just needs to be rebooted. Cabling can sometimes be an issue as well. The quality of the cable can be an issue, or if the cable is a little loose, that can cause it as well. So I would try another cable, it doesn't have to be HDMI at the moment, just to see if it happens with the new cable as well. You can email me at if you have any other troubles.

Our new vizio tv is hooked up just like our old tv, (satellite provider being dish network) and it says no signal with a blue screen

Hello. This is usually an easy issue to fix. To get the DISH Network back on the screen, i have included a few steps:

If you are at TV1, where the receiver box is located, the tv needs to be on channel 3 or 4. Depending on the cable that is running between the receiver and the tv, the tv may need to be on an input, such as video 1 or 2. If you are at the TV2 location, where there is no receiver, then the tv needs to be on channel 60 or 73.

If you are using an HDMI cable, then the TV will need to be on an HDMI input
If you are using Component cables, your TV will need to be on a component input. (Usually Comp 1 or 2)
If you are using RCA cables, then the TV will need to be on a VIDEO input (Usually Video 1 or 2)
If you are using COAX cables, then the tv needs to be on channel 3 or 4 (If you are at TV2, then the TV needs to be on channel 60 or 73)

This issue is actually caused by my cable box. Access the audio SETTINGS on Hand held Cable Remote, and turn on the HDMI and or "Digital Audio Out" option. found on 'more' settings list. This should fix the issue. I had assumed the Cable companeis 'Boot' would have installed this feature during its initialization.

Hi my name is Roety,
I can help you with your issue ,
The cable box signal is received from a round cable called coaxial cable. The guide is sent to the cable box through the coax cable. The HDMI cables sends the picture to the TV.
The Tv does not download TV guide listings , just the box does. That would be a cable company/box issue not a TV issue.
Some TVs have a built in TV guide for when you recieve signals from an antenna (not cable).
If thats what you are referring to don't bother .
Use the cable box guide .

When I connect HDMI from a Time Warner DVR to my Vizio thru a DVI/HDMI adapter, I get no sound. I can only get sound if I use Component input (RGB+ audio R&L). Is this a DVR issue or a Vizio issue?

Use the Time Warner remote and hit the settings button twice. Scroll down to "audio: digital out" and select HDMI. That solved it for me.

The only issue I have now is that I also have component sound outputs going from the cable box to a receiver. When I turn off the TV while the HDMI cable is hooked up to both the box and the tv the sound goes out to the receiver...
