Re: hd audio problems
Seems you have an hardware fault .
You should also test or have tested from a service centre, the DTV
board, which is the main board inside the tv, or the audio board, one of them may be faulty.
if your TV is still under warranty, call Insignia. You just have to pay for shipping and shipping insurance. Otherwise contact them and ask details on nearest authorised service, or part dealer to buy replacements.

The "picture size" on the TV needs to be set correctly. You should have a "ZOOM" button on your remote. Press it a few times, cycling through the options... see if this fixes the problem.
Be advised, many (most) HD channels do not show HD content all the time. At the broadcasters discretion, they may choose to ADD the black bars to either side (and/or top an bottom) of the image. This is what the "ZOOM" button is actually for... to allow you to correct this, filling the screen with the image.
*Note: many cable box have a "FORMAT" or "HD ZOOM" button. When used in conjunction with the TVs zoom feature, you can end up having one device set correctly, while the other is not. The result is often a picture that is expanded far beyond the bounds of the displayable area of the screen. If you can not find a solution using the "ZOOM" button, pick the setting which shows the most image. Now adjust the cable box setting (FORMAT / HD ZOOM).
Make sure that there is sound leaving from the connections on the top box.
Check that the audio cables are connected to the associated audio input for the video at the rear of the set. Make sure that there are no other shared inputs for the same input. With shared inputs, only one can be the default reference for input.
Check the menus in both the top box and the TV set to make sure that all setups are correctly done.
Assuming you have connected the DVD to the component (red / green / blue phono) connectors at the back of the set, and the TV is set to EXT5 then the problem is a setting on the DVP5980.
Check the Upscaling setting on the DVP5980 by pressing the HD UPSCALE button on the unit. Cycle through the options until you get a picture. The 30PF9975/12 is not fully HD compatible, so may only support the lower resolutions. (If any)
If this does not work, connect the DVP5980 with the scart and power on the without a disc in the tray.
Press Setup on the remote.
Press the right arrow button twice to get to the VideoSetup Page.
Move down to the Component setting an change from RGB to INTERLACE.
Disconnect the scart and connect the component lead. Select EXT 5 on the TV.
If the picture appears correctly, go back to the Video Setup Page and change the progressive option to On.
There is no factory option to stop the box from poping up every time
the signal changes, which is what is happening. It has something
to do with signal strength or the fact that your cable box is not set
up for HD. Call your cable company to get a tech out to check
your signal and set up your cable box because they do not come pre-set
with HD defaults.
Normallly, if the picture size button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made. For example: Some Motorola Cable receivers need to be set up in the menu to go to a wide screen or zoom mode when an analog signal is detected. There may be a format button on the remote. Some Dish Network boxes have Size buttons on their remotes and also in their main menu. It's difficult to determine the repair without knowing the types of the peripherals. Hope this helps.
