20 Most Recent Pioneer VSX-D506S Receiver Questions & Answers

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

This is a "protect" mode indicating that there is a problem internally. The most common cause of this is defective output transistors which will need to be replaced. The parts cost for this repair will likely be in the $25-$50 range.

It may be a PROTECT MODE. Check is your other equipment properly connected to receiver.

Could be a dry soldered joint - not unusual in complex electronics but randomly heating lots of joints can cause trouble so it is best to discover the fault first, if possible.
Obtain a service manual and trace the power path with a suitable multimeter.

You could have a bad speaker or wire! If it powers up ok try hooking one speaker at a time and when it shuts down you will know what speaker/channel is causing the problem.

There are a few methods manufacturers use to automatically change the direction of play - sometimes a tight cassette will fool the mechanism into thinking the tape has ended and sometimes it is a matter of the internal control linkages being in such close proximity a slight misalignment can cause the pressing of one button to move another...

Probably not - Bluetooth is listed as a capability but I think if you read the manual, it will be an alternative source or input rather than an output.

Did it work before? If so check there is power at the outlet. Check the back of the unit to see if there is a removable fuse?

Are you an electronics engineer? If so the Service manual is here. If not, Google for 'Panasonic Service'.

'No Sound' is a known issue on that unit.
