Hi robertdesj

I am afraid to tell you mate that the News isnt good. Your amp has an internal problem operating the protection circuit. It may have a failed channel, or maybe a blown fuse... work checking for... be sure to disconnect from the wall before you do anything !!!

If none of the above, I am happy to yak to you more about the problem.

If you think this is good advice, HITME with a "FixYa" rating.
CHEERS!

regards

Amp keep's sating overload


Have you tried disconnecting all the speakers and inputs and turn it on?
If it still shuts off you have an internal problem, if it stays on, connect one item at a time until it shuts off and that is the problem.

I bought a new panasonic home cinema model number sc-pt480eb-k. Its supposed to be 1000 watts but the output it doesn't match that output at all even with all the speakers on. What maybe the cause of this...


Hype on the part of the maufacturer's published specs.

http://service.us.panasonic.com/OPERMANPDF/SCPT480.PDF

Look at the Power Comsumption spec on page 22. "90 watts"

According to this post, 45 watts...

http://reviews.cnet.com/home-theater-systems/panasonic-sc-pt480/4507-6740_7-34024832.html

It would be a miracle indeed to extract 1000 watts of sustained power in any form, be it heat, light, motion or sound from a unit that uses anything less than 1000 watts of electricity, assuming 100% efficiency. Not to mention the dreadful 10% distortion level they use to get that figure.

To say it pushes 1000 watts is dishonest and preys on the gullible.

Have recently had an "overload" displayed. Have


HI:
Usually receivers go into overload due to a bad speaker make sure you disconnect the speakers also to make sure its overloading from a bad speaker. If the unit still shows overload even with all speakers disconnected, then your main amplifier output has a short usually a shorted output transistor is the cause. Unplug the speakers one at a time to and turn the unit on after disconnecting one of the speakers , to determine which speaker is at fault.

When i turn it on it says overload on the screen how do i fix that?


Check your speaker connections for a possible short circuit. Best way to do this is to remove all speaker connections (with the device turned off) and then try turning the device on. If you now don't get the overload message then it means one of the speaker connections or speakers is faulty.

From here add one speaker at a time (always with the device turned off when you plug each speaker in) until you find the offending connection.

If it not a speaker connection causing the overload you should check all other connected devices in a similar way.

If none of these things identifies a problem with a connection or connected device then there is an internal problem with the receiver.

Vsx-517 keeps going into overload mode!


Try this:
1. Turn off the receiver.
2. Disconnect all the speakers from the back of the receiver.
3. Turn on the receiver. Does it still go into overload? If so, it may need repair.
4. If not, turn the receiver back off and connect one speaker at a time and turn it back on.

Most likely one of your speaker cables is shorted out causing your receiver to get overloaded. Or, one of the speakers is damaged, having the same effect.

Overloading


hi mate, ive had the same problem before with this amp. i bought it new aout 6 years ago and bought another new one about 1 year ago, new, for £70!

on the first amp there was a problem with the surround sound aspect, it kept overloading when turned up even a fraction, it would tick 4 times and power off. Eventually the surround sound stopped working all together and whenever selected made a VERY VERY loud hissing/crashing noise through all my speakers, blowing one of them, SO BE VERY CAREFULL.

when that happened i assumed was broken so bought another one, and had same overload trouble when i got a new speaker package.

Im pretty dam sure it was the ohmage ratings being different on 2 of the surround sound speakers that srewed the 1st one, so id suggest you check theyre all ok, as well as the speaker watt-age.

what are the specs on all your speakers (ohms and watts RMS)??

do you listen to LOUD music through the 5.1 option??

hope this helps, if all else fails buy a new one mate, theyre so cheap. go into panasonic shops and see if they have any left.

Overload?


From the manual, you may have seen this: Switch off the unit, determine and correct the cause, then switch the unit on. Causes include: ?Shorting (bare wires touching) of positive and negative speaker wires. ?Using speakers with an impedance lower than that rated for this unit. ?Straining of the speakers through excessive volume or power. ?Using the unit in a hot environment without proper ventilation.
