Try to plug it into a differen outlet. Also unplug it and open the case and look for a glass tube should be small and see if you have one in that case. If not then the cost to repair is high. You should get an estimate of how much the local repair should would charge you first. If it cost too much than what a new one would cost then don't repair it keep the speakers and get rid of the amp. But a new amp or another system if you want.

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.

Sounds like it is going into protect. This is usually caused by a problem in the amplifier section. I would start by making sure none of the output transistors are shorted.

I just bought a Panasonic SA-PT480, set it up, step by step per the manual, powered through 2 surge protectors( the second surge protector is used to completely cut power to devices that dont need constant...


I can't find a manual for this thing, which I believe is part of the SC-PT480 package.

I'd plug it straight into a wall outlet for further fault isolation and treat it like it has never worked, no assumptions.

Surge protectors only address outside power surges. Overheating, speaker shorts yada yada can still happen. Effective self-protection circuitry activation need not be preceded by smoke and light shows.

When the audio cut off did the unit also die, or did it look otherwise alive? If the former...

Generally speaking, an amp protects itself from heat, shorts and overloads 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.


Check for loose speaker connections as a root cause for intermittent shutdown.


Maybe a sleep timer clicked it off. Or if it seems to power on but remains silent some other setting like muting, tape monitor got activated. Or the source audio died. Lots of things.

My box is hooked up but it's saying no signal...I read a post from another person with the same problem and what the "Expert" said. I had already done the scan thing but it's still telling me no...


What type of antenna installation are you using? Do you have it aimed at your local transmitters? Do you have tall trees or buildings that could block the signal? Do you get signal from a low-power analog station in your area (pass-through or direct)? If you have an analog station with a transmitter near that of the digital ones, you'll have some idea of if the antenna is pointed correctly. (Digital signals do not get tuned in the way a weak analog signal does. There is no poor picture option; you either see it or you don't).

Go to antennaweb.org or tvfool.com for information on station transmitter locations that you should be able to receive (if in the US). Just enter your address. Antennaweb is very conservative in the channel list even though it assumes an external antenna. Tvfool gives recommended antenna types for each transmitter in your area. The antennas are labeled with a color code by the manufacturer.

If you are sharing the OTA signal from your antenna with several TVs, you may need an amplifier.

I've had one D-T-A box fail due to a lightning strike hitting the antenna; the tuner was damaged by the power surge. I've also had amplifiers that lost the VHF (2-13) channels after a surge. If you have a lightning protection system, check it as well. The simplest diagnostic for these problems is checking if a new D-T-A box or a TV with a digital tuner can scan the channels and then check what the signal strength is for those channels.

Some tuners are more sensitive and will receive a channel that another tuner might not see as a strong enough signal. An amplifier can be useful in this case as well. (With the amplifier that got hit by lightning, one TV was still receivng channel 7 but the signal strength was 1 out of 7. The other TV got no signal due to a weaker tuner. Since that channel was from the closest transmitter, the amplifier was checked once the antenna direction was confirmed to be unchanged.)

I hope this helps.

(Antenna type, tall trees and direction are big issues. I set up a neighbor's DTA with an indoor antenna that got one set of stations. Due to placement issues, their other TV got a different pair of stations with another indoor antenna.)

Same Problem, Speakers Do Not Turn On


If it's still under MFG. Warranty, get it replaced. If not, weigh the cost of repair vs. replacement. What has more than likely happened is the unit has seen either a "Brownout" severe voltage drop then spike to commence power, or a power surge. It's a very common problem with today's electronics of all kinds. It will either have a bad power supply or bad transistors and will range from $ 125.00 - $ 175.00 to repair on avg. When you have it replaced or repaired, make sure you purchase a good line conditioning surge protection unit like Monster, Panamax, or Furman. Not a power strip, that's just a glorified light switch. Sorry for the bad news! Hope this helps

Magnavox MRD-510- when I plug it in, it just makes a clicking noise and the power button keeps flashing. When I unplug this unit it continues to click for 5 seconds. Only owned for about 5 months and now...


Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.
