Those are 2 separate questions and I'd prefer to deal with them in that way. I suspect that you are unable to access the HDMI settings from the menu as the TV is in the wrong mode. Try pressing the button marked "DTV" on the original Pioneer remote to switch the TV to digital viewing mode. Then open the MENU again and see if you can access the HDMI settings.

You also need to select the HDMI input source on the TV. This can be done by pressing the buttons 1, 2, 3, 4 near the top of the remote under the heading "INPUT"

When you have got the HDMI input working correctly we can move on to connecting the sound bar.

You did not actually specify what the HDMI source is, e.g. Cable box, DVD player. I really need to know the details of all of the equipment you are trying to setup to assist you further. It will be difficult to assist you further unless you can reply to me with these details.

    I'm sorry but this is getting more confusing by the minute. Firstly, there is no Pioneer PDP-512-LR plasma TV. The closest Pioneer model number to this is PDP-S12-LR, but this is a speaker system, not a TV. Secondly, what exactly are you trying to connect with an HDMI cable if your TV has no HDMI sockets?

    Please take a little more time to describe exactly what you are trying to do and what the problem is. I can't assist you properly if I have to figure out what you are trying to do before I even attempt to solve the setup issues. Please also check the TV model number you provided.



    DILLIGAF Dec 31, 2010

    OK - Thanks for the info. I think this seemed more complicated than it actually was. All you want to do is connect the Pioneer receiver to the Panasonic surround sound system.

    The PDP-R04U does not have any HDMI OUT sockets so you cannot connect using an HDMI cable. You will need to use a different cable type to connect the receiver to the surround sound head-unit.

    The only suitable AUDIO OUT socket on the Pioneer receiver is the DIGITAL OUT / OPTICAL socket. There is a corresponding DIGITAL IN socket on the Panasonic head-unit so this is the cable you will need to use.

    However, none of this will work unless the Pioneer receiver has an audio signal to send to the Panasonic head-unit. One of the Pioneer receiver's AUDIO IN sockets must be connected to an AUDIO OUT socket on your TV or cable box for this to work. If not, there is no sound source for the surround sound system.

    If you've connected the receiver to the surround sound system with the DIGITAL OPTICAL cable and still can't get it to work, please post back for further assistance. You will need to give me details of everything that is connected to the receiver and how they are connected. Basically, I will need to know exactly which sockets you are using on the PDP-R04U and where each one is connected to.

    Hope this helps.

    Hello again. I will reply to your question in a minute. Please note, my comments will soon start to appear on another page. If you are notified of a new message from me and are unable to find it, please scroll to the bottom of my last visible message (probably this one) and then click on "View More Comments" in the blue bar directly below.

    DILLIGAF Jan 01, 2011

    OK, The only reason, I can think of for why you can't get it to fit would be that you've bought the wrong cable. There is only one size of digital optical cable, but there are different types and sizes of digital audio cable.

    The cable you need is the digital optical - it will look like this at both ends:

    Please note: The cable must be inserted the correct way up or the rounded-corners will not fit. Do not attempt to force it if you cannot insert it easily and do not attempt to connect any other type of cable to the Digital Optical socket.

    If you have bought one of these cables then it needs to be connected to this socket on your Pioneer receiver:

    The other end needs to be connected to an identical socket on the Panasonic Sound Bar. Unfortunately, I cannot find a picture of this socket of the Panasonic, but there is definitely one there. I believe it's located in a recess on the back, under an HDMI socket.

    Please confirm that you have bought the correct cable as above.



    DILLIGAF Jan 01, 2011

    Sorry - the picture didn't upload correctly. This is a digital optical cable:

    DILLIGAF Jan 03, 2011

    That's great news - I'm glad you got it working and I was able to help. I hope you got a refund from 6th Avenue Electronics? Happy New Year to you too! BElectric.

You have to turn up the volume to 38+ in order to hear the TV, when you use to be able to hear it at 10, is there a control board that goes out and what Is the name of it?

Hi Geoff, I hope I can help you with this. If you are using an accessory device (DVD, DVR) check cables to see that they are secure and if device has audio out option that it is set correctly. Also check to see that Video and Audio cables are connected to matching inputs on your set.
If you are using DVI to HDMI you will need to use a separate digital audio cable. DVI cables do not carry audio signal. After attaching the audio cable if you still do not hear sound you may need to set Digital Audio In. To do so:
  1. Press Menu Button on remote.
  2. Press the cursor ring down to highlight SETUP.
  3. Press the cursor ring left to enter SETUP menu.
  4. Press the cursor ring down to highlight SOURCE.
  5. Press the cursor ring left to enter SOURCE menu.
  6. Press the cursor ring down to highlight DIGITAL AUDIO IN.
  7. Press the cursor ring down to select the source you want to associate Digital Audio with. HDMI 1 or HDMI 2 in this case. You might need a software update also.
    The latest software solves the issues below:
    1. TV (Plasma 42" and 50") will not turn ON/shut off itself and Red LED blinks 4- times. Recover if main switch on/off.
    2. 37" LCD full white screen appear when upgrade software.
    3. Some channels not available after turn ON.
    4. Delta volume changes, not remembered.
    5. Preferred channel changes, not remembered.
    6. Green or yellow static (sometime snowy) on HDMI picture.
    7. Picture and sound loss for 5 to 10 sec (green LED is still ON) and back to normal.
    8. Audio loss in all inputs and can be recovered when main switch ON and OFF.
    9. TV set turn ON by itself/ green LED light up and goes off when set is ON.
    10. Intermittent audio loss in NTSC RF channel.
    11. Crack sound with high input signal.
    12. Include the possibility to download the rating table (RRT5 capability) for digital programs.
    13. No video/ no picture with sound.
    14. Intermittent On-Screen Menu pop up by itself and can be removed by pressing the 'MENU' button.
    15. Channel information display too long.
    16. Improvement on scramble channel.
    How to check the current software version on my TV set?
    1. Press 'MENU' button on remote control to display the on-screen menu.
    2. Select TV MENU and press the cursor right.
    3. Select INSTALLATION and press the cursor right.
    4. Select SOFTWARE UPGRADE and press cursor right.
    5. Select CURRENT SOFTWARE INFO to display the current software version on your TV set.
    6. If the TV software version is lower than the version posted on the website means your TV set needs to be upgraded.
    7. Follow the instruction in the user manual or Firmware Upgrade Readme file on how to upgrade your software.
    Where can I find the latest software for my TV set?
    The Firmware Upgrade Software and Readme File documents can be found on the Philips support website. Refer to the SOFTWARE section.

Boot menu

Your computer's BIOS, or basic input/output system, regulates several important system functions before your operating system loads.
The BIOS can even tell your operating system which device it should load from, whether the computer's hard drive or a USB stick.
You can control this and other options from the BIOS boot menu.
If you own an Acer Aspire One netbook and want to access the boot menu, you can do so by entering the computer's BIOS.

Turn off your Acer Aspire One netbook.
Turn it back on.

Press "F2" when you see the Acer logo appear as the computer boots up.
This will open the computer's BIOS menu.

Press the arrow keys to highlight the Boot option.
Press the down arrow key to highlight specific boot settings to change.

Windows operating systems support a variety of boot options on the Windows Advanced Options Menu that allow you boot your computer based on your need.

They support boot options such as Safe Mode, which is generally best for troubleshooting and virus removals; or the Safe Mode with Networking, which allows to use an Internet connection while troubleshooting system problems.
Within seconds, you can access the boot menu and select the option that works well for the task you want to accomplish.

Shut down all currently running programs and restart your computer.
Press "F8" repeatedly before the Windows icon shows up on your screen.
This will bring you to the "Windows Advance Options Menu."

Scroll down and select the boot option you want.
Press "Enter."You can select from "Safe Mode" "Safe Mode with Networking" or your regular booting option.
Choose the boot option based on your need.
For troubleshooting, it is advisable to select "Safe Mode" because only a certain amount of drivers and resources run allowing you to resolve issues.
