Find the remote specific to your TV and try switching input settings, using the "source" button.
SOURCE: plasma tv/home theater
Is your Panasonic set to monitor the HDMI input? Just like selecting a mode input on the Tv you must also select the mode input on the surround system.

you have a delay time on your home theater JVC, that is normal. So it's either you reduce the delay time of your JVC or do not use the TV sound. Set the delay time of your DSP so you can heqar the sound you wish... like the delay time of your surrond.
SOURCE: surround sound and TV sound
Not by just pressing a button the Home Theatre no , I have the same problem on my Panasonic system - and I just mute the TV.

Sounds like a possible solder issue with the vertical output IC. Try resoldering the Vertical output IC connections
SOURCE: No Picture No Sound other than chirping
From description you provided that the red light is on or a stand by light and a chirping sound,chirping come from horizontal section maybe H-OUT transistor is busted. Look also the power supply section is in the P-BOARD which has the reading of test point =170v, P-board is a power supply board ,bad regulation of the incoming voltage could cause the issue and maybe there is a capacitor across the incoming line which dry up or leaky already and cause the problems ,change it out with one identical rating.
Also Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the TV turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.
Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".
Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If i have helped,please click fixya.It is the only way i get paid for my work...
Good luck:
