I have a sony s-master digital amplifier which will not power up: when I plug it i to power it takes about 30 minutes before the red standby light comes on but no other functions operate.


So the standby indicator never changes state? If so, more than likely, your amplifier has DC Offset(a damaged amplifier inside) which will keep the speakers off, and disable any use of the front or remote functions. If you are interested in having your Sony repaired, please refer to my website, audioserviceclinic.com. You may contact me there. Thank you.

Why is my speaker not working to full capacity


Hello, First, check the bridge switch located on the rear of the amplifier, should be on STEREO position, GROUND switch to GROUNDED position, check front potentiometer for dirt or scratchy sound as turned it up or down, if none of this solve your issue then could be an internal defective speaker output relay, or channel fuses, let me know if you need further assistance, Regards.

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.

No sound


When the amplifier will turn on but not produce any sound that is usually an indication of either the high voltage power supply inside the amplifier is not working, or the amplifier IC or amplifier circuit is damaged. It is not something that can be repaired unless you have experience working on electronics.

Sony Model No STR-DE475 blinks "PROTECT" even with no speakers


With all speaker wires disconnected and still showing the protect message, the short is internal. This is a rather common failure for these units. The output transistors are shorted themselves. These are relatively simple to replace and run about $15 each. Any service shop that repairs audio can fix this easily. Usually, once the outputs are replaced, you can get many additional years of service from the unit. Yes, it is worth it (in my opinion).

Technics su g70 amp problem also?


it doesn't sound like it. but maybe. it would be the input section of your amp that blew if it did go. try replacing your speaker wire first, if that doesn't work then your volume knob(if the volume is analogue) may need to be replaced. if that doesn't work. then you may have blown the amp. what source are you testing with?(cdplayer, dvd player, etc.) and what inputs are you using? (analogue, digital optical, digital coax)

This is not a reset. Most likely one or more transistors have shorted and need to be replaced. Does the front display come on OK?
