Panasonic Home Theater System ....No power


Likely a power surge hit your house while away. This happens when power turns back on or lightning hits close to your house. If insured, call insurance company about it. You may be covered for replacement or have deductible applied. Small appliances like this are most susceptible to power surge. There is not enough protection designed in.. The best protection is surge module on main breaker panel or buy a protected power strip to protect high value electronics.

Comes up when switched on protection


Protect occurs when 1 or more of your speaker wires is touching somewhere. Power off the receiver, connect speaker wires to receiver and speakers again, power back on, should fix the issue.


Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

Twice now our router has failed to work after lightening strikes. The UPS means its lights still flash etc but the router itself does not work. Why does the UPS not protect it and what do we need to do...


A UPS is generally not designed or manufactured to protect against lightning strikes and / or power surges. Its purpose is ensure that whatever it is supplying power to does not turn off in the event of a power outage. You would be better served by getting a lightening protection strip from a hardware store that comes with insurance against damge from lightening and power surges. Alternately at substantially more cost, you can have an electrician or lightening protection contractor install whole-house lightening protection. Lightening protection strips with insurance included are relatively inexpensive.

Amp in power protect


Protection Circuit is bad. It needs to be serviced. If all speaker wires are disconnected and it's still in protection, it's got a problem. Hope this helps

UPS issues with bad power


First, most of the UPS sensitivity can be adjusted. Setting a higher sensitivity will make the UPS compensable much faster if the current goes to high to too low thus always providing a good power quality to the equipments. For example, on a BackUPS RS the low level can be configured from 94V to 104V and the high level from 126V to 136V. An entry-level UPS such as the APC BackUPS ES will switch to battery mode as soon as the power goes out of the sensitivity range. On the other hand, a high-end UPS for workstation like the APC BackUPS RS has a feature called Automatic Voltage Regulation (AVR) that compensate at some extent without requiring the battery; this makes the battery last longer before needing to be replaced.

Second, most of the UPS have "Battery Protected" and "Surge only" outlets. Make sure that the computers are connected to the "Battery Protected". The "Surge only" outlets will only protect from parasites or surges like a thunder storm. They should be used for less important stuff like a desk lamp or devices with high demand peek such as a laser printer.

Third, the use of a power bar connected to the "Battery Protected" side should not have any impact as long as it is not overloading the UPS. Personnaly, I have a power bar connected to both my UPS.
