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:

Tv won't power on

There are several possible reasons why your TV won't turn on, follow the troubleshooting steps below to isolate the issue:

1.Make sure the AC power cord is plugged in to the TV

2.Make sure the wall outlet is working and matches the voltage requirement of the TV (AC 220 - 240V 50/60Hz).

3.Check the status of the Standby Light located on the lower right corner of the TV. If the light is on, it means the TV is receiving power.

4Press the Power button on the TV for a minimum of ten seconds (power button is located on the back of the TV, depending on your model.

5.Unplug all cables attached to the TV and plug in the Power cable securely and try again. A faulty HDMI or audio cable could be interfering with the power supply on the TV.

Why does my Netflix have sound but no picture?


Your device may be experiencing an HDCP issue that is preventing Netflix from playing your content. To resolve the issue:

1. Ensure that you are using an HDMI cable.
2. Bypass any receivers or stereo equipment by connecting your device directly to your TV.
3. Try reversing the ends or try a new HDMI cable.
4. Try another HDMI port on your TV.
5. If available, try an HDMI port on another TV.
a. If you were able to stream on another TV, there may be an issue with the HDMI port on the original TV. Contact the TV manufacturer for further assistance.

Video drop

Try to isolate the offender. Start with one device and see if the problem remains. After a period of use, add in another component and see if the problems reoccurs. Once it does take out that unit and add in others, in the same manner, to see if others cause problems or the number of devices is an issue.

I had a lighgting strike near the house and now my xbox has a black line through the screen but not the tv and no audio!

Hi, robandcarlie!
If your xbox is still functioning correctly and it only shows displays issues, maybe the cables were damaged. Try using a different set of video or hdmi cables when connecting it to a TV. If this still doesn't work try isolating the issue by trying the console on another TV to see if it's a TV issue or a Console Issue.

If this didn't fix your issue please let me know. Hope this helped you!

Assuming a single cause we need to isolate which single device is involved in all these failure modes.

"It comes out of both speakers" on what - the TV?

You don't say how the DVD interefaces with the receiver. Is the DVD feeding digital multichannel audio out at that time? Many DVD's are simple stereo until the show actually begins. You know that.

Try running an HDMI connection straight to the TV from the cable box. Result?

Substitute the other HDMI cable for the first one. Result?

If either one does NOT work satisfactorily we may have part of the problem isolated.

If they both work, the TV and cables are ok.

Attach the HDMI out of the receiver and IN to the TV and the HDMI from the Cable Box as before. Same result?

Can you try using Component Video out of the receiver to the TV just to change something in the equation? On my rig I 'see' no difference between HDMI and Component Video on my HDTV. A change in the result may help to isolate or work around part of your problem.

My $.02...

I'd recommend you go for minimal receiver involvement in the video side other than to send composite video to the TV from "Monitor Out" so you can set up and manage the receiver.

You can also send Cable- or Sat Box basic analog audio directly to the TV if it has inputs for audio. That way if you just want to watch the news or weather you don't need to fire up the Pioneer.

Your video sources (DVD, BD, Cable/Sat) will suffer fewer video anomalies if you send their best video directly to the TV and their best audio directly to the receiver. That way everything is handled only once by the best electronics you have for each function.

If you've had this happen with two systems in a row, then it may not be the systems. First, try hooking up the PS3 directly to the TV, or another TV, and see if the issue still occurs. If it does, then something between the PS3 and the TV is causing your issue. Otherwise, call and get it replaced again, and hope the issue doesn't happen again.

Harman Kardon AVR 154 OSD setup screen wont display

It will only display via component. Your HDMI firmware is either 1.1 or 1.2 and has HDCP issues (High Definition Copyright Protection) it's a firmware problem that has been fixed on all new receivers, not just a HK issue, all receivers! the new version 1.3a and 1.3b have fixed the issue. Unfortunately you cannot update the firmware on the receiver. Hope this explains it for you, sorry! Lot's of angry people out there!!! myself included.

Have you tried a different input on your TV? HDMI communicates both ways. You could have an issue with the input port on the TV. Try using Component. If you still have issues post a reply and we can dig further into it. Hope this helps
