Poineer deck amplifier dc-z74 relays click but set deck does not come on no display lights dead unit


Part of your PowerSupply is Frito.
Probably the +/- 15 volt rails, could be other.
Check inside power voltages, probably some regulators are gone.
Preferably get a tech unless you have the know-how and test equipment...

I have a Sony Amplifier [model TA-AX380] and other components of CD player [model DCP-C40], AM/FM Tuner [model ST-JX380], FM Stereo/FM-AM Receiver [model STR-AV570X], and Stereo Cassette Deck [model...

Hi above are links for manuals, these may help..
When one wires up anything it is all usually color to color output to input... usually RED & WHITE stereo audio.
Now we would start with our Tuner this the CD player, & Cassette deck, will wire into the Amp's INPUTs , red - red & white - white, these go into the Stereo INPUTs on the AMP... 1, 2 & 3 and be selected via the input selector on the AMP.
Now after all these in's and out's are wired we need to wire our speakers, this too is simple, locate the outputs on the Amp, and wire accordingly, Plus to Plus and Negative to Negative... each speaker has two wires a Plus, + & a Negative -
All will/should be clearly marked and it will be easy to do. You will need patch leads, one set each for each unit, these will be a pair of cables, usually Red & White with RCA jacks on each end, as related these go color to color from the RCA OUTPUTs Sockets, of the signal suppliers, ie: Tuner, FM stereo & Cassette deck... these ALL will wire into the Main Amplifiers INPUTS, usually at rear of unit, and clearly marked, after this is all done, then as related again now connect the Speakers, again the OUTPUT on the Amp will be clearly marked, as output and + & -, + & - (two sets), one for each channel.
Now each INPUT is selected ON the AMP, and it's output will then be directed to the speakers attached to the Amp..... Just wire and test one at a time, and i am sure you will prevail.
Hope this helps.

When i make phono input..The Volume come very big.And all other input selecter volume come normal.


As long as the phono input is only being used for a record deck the most likely cause is a faulty magnetic cartridge pre-amp. If you are connecting any other device to these sockets, remove it and place it in another socket. If you haven't got enough sockets you can get a switching box to solve the problem. If you are getting the problem due to a record deck, make certain it hasn't got a built in pre-amp first, check the cartridge and wiring to it and all deck connections. If still no luck then you will find that you need to replace the pre-amp. It will be a single IC, which can be found by following the wiring from the phono sockets inside the amp.

All sources or just one? Make sure the Tape Monitor isn't engaged unless you're using an external tape deck or processor. A turntable will only work on the PHONO input.

The amp turns on but has no sound coming through the speakers


There should be several channel choices and speaker connections, make sure they both match.
If you are not sure, put the amp on main or 1 and try all the connections until you find the ones that sound is being routed to.
Also overload protection is pretty sensitive, if you have touched wires together or mixed up + and - you may have tripped it, and may need to reset.

No sound to remote speakers in dining & deck areas.


Incoming from WHAT? Ampifiers accept inputs via RCA connections and send amplified audio to the speakers via the + and - OUTPUT terminals.

I'm guessing your colored wires are from your speakers and that there is a piece of this puzzle we do not see - how the speakers on the deck and in the dining area are wired.

You say, "was working ok previously"... previous to WHAT? Something changed.

You can probably troubleshoot and resolve this yourself.

Set the amp to a medium output level.

If the wires are simply leading to either or both pairs of speakers you could select any two of them and connect them to one side of the amp. Only a pair going to the same speaker(s) will produce sound. Once you identify one pair, the other pair probably goes to the other speakers. Connect them to the other channel output.

The last piece would be to establish correct phasing between the speakers. Bass response will suffer if they're not IN-phase. Play something with substantial bass. Listen closely, then reverse the wires on one side only. Test again. If it IMPROVES you have it right. If it losses bass, put the wires back the way they were.

No sound from cenre and rear speakers


Is there an output section for the speakers on the back of the receiver? if so, make sure to properly install the speaker wires into the correct connectors. It should be the same as for the front speakers. If not, then you will not be able to install center and rear speakers.

Make sure there is nothing wrong with the speakers, or the wires them selves. If you are positive that everything is installed correctly, try using a new batch of speaker wire. If the speaker wire is pre-installed or already attached to the speaker from the factory, you might have to call and report a faulty product or try to find the break in the wire yourself. To make sure the speakers are working properly, be sure to plug them into the same connector as the front speakers to see if they receive the signal. if noise comes out of them when plugged into the front slots, then the speakers themselves are fine, and it is an issue with the wires or the unit itself.

Last, if it is not the speaker, or the wires, then you will have to remove the cover from the receiver or remove the wire inputs from the back of the receiver and make sure there is no connectivity problems with them. There might be a frayed wire, or a wire that has come loose, or a soldering issue. If so, you can try to tackle it yourself, or you might have to bring it into a repair shop, or call Sony.

Hope this helps at all. :D

Last, if you have tried new wires,

Amp's lights come on, but no sound from speakers


It sounds like the output transistors are faulty and that they took out the fuses when they failed. At this point the protection circuits are kicking in and preventing the output section from turning on. Can you please reply to this and post the make and model? That will help me to give you some information about what is needed for the repair.

Thanks,
Dan

Sony output problem


All i did was mess with the REM wire, and found out i had to hook the REM wire to the blue/white wire on the deck. Instead of the blue/white wire, i had it hooked up to the solid blue wire on the deck which was preventing my amp from playing on CD.
