I have had my Panasonic for about 2 1/2 years and have not changed any setups or the way cables are plugged in. When I switch from HDMI 2, my satellite input, to Video 2, where my DVD player has always been, I get fixed (not moving) horizontal noise on the screen and no picture. The same happens when I hook my computer up to Video 3 where I've had it many times before. I also tried another DVD player to make sure that it wasn't the player, and got the same result. What could be causing this ?

This is a known problem. Panasonic sells a jig to correct it. I had the same problem and bought the jig for $60. It plugs into a special port in the back of the tv behind a little door. You can read all about it here: http://www.avsforum.com/avs-vb/showthrea... if you want, contact me by replying and I can mail you the jig temporarily for $10 plus S&H. You'll save money and it worked for me, i just need it back.

Usually when you have a red tint when using the component input i'ts because the wires are switched on one end or one of the 3 video wires is bad. See if blue and green are switched.I see this all the time. Is your picture grainy on all input?

Symptom:
TV shuts off unless all the input (phono and HDMI) cables are disconnected. The
symptom may be intermittent.
Cause:
There is an abnormal AC voltage entering the TV from one of the input cables or AC
outlet.
Remedy:
Follow the Testing procedure to determine if there is a problem external to the product.
Concept
Constant symptom
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
protection.
Intermittent symptom
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.
Protection Proof:
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.
Testing -
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.
SOURCE: HDMI inputs don't work
No, but the HDMI interface is very sensitive to static discharge - has been a storm nearby? To prevent this from happening again i usually install to all my customers cheap splitters just before the tv, they will fry before the tv protecting it.
I'm sorry but it's time to change that board again.
