It can also be the YMain board or the back light inverter board or a capacitor or fuse has blown on the power supply board. Which you usually lose sound before you lose both sound and picture. Try to hard reset is for about 4-6 hours by completely unplugging it.

SOURCE: How do I remove the stand from a panasonic tv. model TX - 32LXD70

The stand is held on by four screws. Lay the tv face down on a flat surface. Cover the surface with a blanket first. Use a regular phillips screw driver. (If you have a users manual see page 7)
The screws are the set just above the stand on the back of the set. The stand will then slide out.

SOURCE: Panasonic TH-46PZ85U Plasma TV

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.

Need to know more,what do you see on the screen?
if the lcd was faulty there would still be sound.
if you have changed the av board have you checked the voltage supply to it? have you checked all the visible electrolytic capacitors on all boards for bulging or leaking?

please let me know how you go..
