Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Hi there, sorry to hear you're having trouble with the panasonic
there are several possible causes of this
can you please clarify, is it really turning both on and off by itself, or does it shut down while in use, then stay off?
If both on and off, what is the frequency, and does it only happen during regular use, or is it happening spontaneously (turning on when you weren't already using it)
Thank you for the information,
this is most likely a defective power supply board within the theater system
can you please dry disconnecting everything from the receiver unit (all speakers and any attached components),
then power it on with nothing connected except the power cord
you can try to play a dvd then, and observe what happens
if the problem stops, then it was being caused by an electrical short in an attached speaker/component,
if the problem continues, it would confirm that it is internal to the receiver (a hardware failure).
That is something that would require repairs to correct, which honestly is not worth the investment. These units are not really meant to be serviced, and at 10-12 years old, it is well past it's expected lifespan, so it would be time to replace it with a new system.
You can keep this chat open if you need some time to observe it
since you mentioned it will work for awhile before the switching starts
Okay, go ahead and keep an eye on it for awhile, I'd say at least 10-15 minutes
continue to operate it with nothing else connected
we need to observe if the problem returns in this state, to isolate if the cause is internal or external to the receiver
Thanks. I'll wait for your update, take as long as you need
That is actually good news,
it tends to indicate that the problem is external
Now comes the tricky part
which is isolating the problem.
it isn't difficult, just time consuming.
Basically, we need to reconnect everything one at a time, and observe
so reconnect just 1 speaker, give it 10-15 minutes, if still good, add another speaker, etc
then if it is okay with all speakers connected, start adding in any component connections (cable/satellite box, etc)
if the issue comes back, then we can most likely attribute it to the last device connected, though it is still possible this is an internal short in the amplifier that is only happening when the speakers are connected
Further testing will help us to isolate the issue though,
and we can then address it when we know more
Yes that is exactly correct.
One at a time, connect a speaker, wait and observe. If okay, connect the next and observe, etc
You can leave the chat open, or bookmark/favorite this page to get back to me when you have a chance.
I'm online most all day (I'm in the US though, pacific time). If it is more convenient for you, your'e welcome to follow up with me at another day/time as well.
Great, glad to hear it
so that most likely means that what was happening before was a short in one of the wires,
even a single strand of speaker wire touching another wire or the back of the receiver could cause a problem, as could reversed connections, etc
in the process of moving things around, you probably just inadvertently got everything back where it belongs, clearing the issue up.
Just keep an eye on it, and if the problem starts happening again, then it is more likely to be internal. If that is the case, you can try blowing it out well with compressed air, to remove any dust inside that could be causing overheating. Beyond that, we'd be back to considering repair/replacement for an intermittnet internal failure.
You're welcome, and good luck!
