SOURCE: 42" pansonic plasma hdmi problem
if I understand your question properly.. its because your direct tv output doesnt broadcast in high def so its giving you the standard tv definition inputs which are RGB or Component.so you will lose picture quality cos its running at fewer lines or pixels. hope this helps

Using your input key on the remote should switch you to the other modes. If you cannot access any HDMI or other input labels, go to your menu, and into the Input Labeling menu (under settings) and make sure you have all the inputs you require enabled. Its possible you (or an out of the box error) put these other inputs offline, which is why you aren't able to access your media from HDMI. If all inputs are enabled, and labeled, double check all the HDMI inputs on the unit. Plug what you are using with HDMI into each port, having the power on and sending information to the television. In some rare cases, I've seen that it doesn't allow access to the HDMI without it providing some source information.
Hope that helps.

Hi, you probably won't get audio from the HDMI port on a laptop post the exact model so I can check for you, you can get an adapter from the audio out to the in on the TV, as for the resolution, lower the resolution on the laptop before connecting it, simply right click the mouse anywhere on the desktop, then left click on properties then settings, then pull the resolution level to 800x600 save by clicking apply and OK , try a few settings to get the highest resolution the TV can display correctly.

TV shuts off unless all the input (phono and HDMI) cables are disconnected. The
symptom may be intermittent.
There is an abnormal AC voltage entering the TV from one of the input cables or AC
Follow the Testing procedure to determine if there is a problem external to the product.
If the TV no longer shuts off when all input cables are disconnected, then one of the
input cables is introducing abnormal voltages into the TV. Panasonic Plasma TV sets
have 3 wire AC plugs.
As a result, abnormal voltages introduced into this TV will cause the TV to shut off for
If the abnormal input voltage is borderline (marginal), the TV shut off symptom may be
intermittent. However the cause may still be detectable with a voltmeter.
Release the protect mode - the TV has to be unplugged to reset this protection circuit.
Threats from the HDMI input:
Excessive voltage from an HDMI cable connected product will activate the Plasma TV’s
protection circuitry. Placing an isolating / buffering connector (sometimes called a voltage
conditioner) between the TV and the HDMI input cable often solves the problem.
Unplug all the HDMI inputs from the TV. Turn on the TV. Plug in the HDMI inputs one at a
time. The cable that causes the TV to enter the protection state is connected to the product
that has the excessive voltage (and signal). Avoid connecting this product until an isolating
connector is found.

The Panasonic doesn't detect the presence of the signal on the antenna input so it just skips it. shut down the player and turn the cable box on before attempting to switch sources.
But why aren't you using the Composite RCA connection on the cable box ? Not only you would get a much better image but the tv would detect that change in the AV source and should switch by itself. If it doesn't then the control processor is faulty and the entire mainboard will will have to be replaced
