Question about Amplifiers & Preamps

This unit suddenly stopped sound output to both channels - the twin cassette decks, CD, tuner and turntable all work fine - there is just no output to the speakers - i suspect the power supply unit has failed but have checked both fuses and they are OK.

Is this one of the units that has a ribbon cable ( looks alot like an IDE hard drive cable) that connects all the components together? It also has a squre plastic fan that protrudes slightly from the rear (by about a 16th of an inch)? If so, it's the power module which consists of 2 boards (along the fan housing). You can probably find replacements for about $70, but I wouldn't bother. They quit making new replacements several years ago and any board you get now is just a pull from old stck units.... and they fail about 2 minutes after you put them in. Pioneer knows this but still sells the defective parts.

There are a number of amplifiers in the TA series, but the connections are basically the same.
In your system, the amplifier serves as master control. How do you know? Look for the component that offers input selection -tuner, cassette, CD, video, phono and probably auxiliary. Every other component plugs into and is controlled by the integrated amplifier. For example, plug the tuner wires from the tuner output to the amplifier input marked "Tuner." To use the tuner, just select that input from the front panel. Same with all the other components.

On the back of that unit will a bunch of RCA jacks for left and right channels. Take the hook-up wires, usually RCA cables with colored plugs on each end, and connect the OUTPUT jacks on each separate component to the INPUT jacks on the amp. Power may also be controlled from the amp. On audio plugs, red is right and white is left. Keep the polarity constant as you connect each component. Connect the speaker wires to the speaker outputs, usually spring clips or screw terminals on the amplifier end and the same on each speaker. The DVD video cable will have three wires: Yellow, red and white. Yellow is always video. It may also have a little round video connector for S-VHS which provides a much better picture when using DVD.
Select your desired input and enjoy the show. Service Manual free download schematics datasheets eeprom bins pcb...

Tuner problems

If you can hear music from other sources then it likely that it's the tuner that has the fault. Most tuners these days are one or two IC's. I would suspect them in this case. You can find them easily as there will lots of coils around them.

For connecting these to your amplifier you need 4 Stereo RCA Cable.
1.Connection for cd:
Take one of the RCA cable connect the one end (red/white) jack to the line out of your cd and connect the other end (red/white) to the CD input of Your amplifier.
2. Connecting the tunner:
Take one of the RCA cable and connect the one end (red/white) jack to the line output of you Tuner and connect the other end (red/white) to the TUNER input of your amplifier.
3. Connectiong the tape deck:
Now you have two RCA cable. Take one of the RCA cable and connect the one end (red/white) jacks to the PLAY out of the Tape deck and connect the other end (red/white) to the TAPE 1 play input of your amplifier.
Now connect the last RCA cable. Connect the one end (red/white) jack to the record input of the TAPE deck And connect the other end (red/white) to the TAPE 1 Record input of your amplifier.(this connection will help you to record to tape from cd or tuner. if you are not interested in recording then you can avoid this connection.)

Now you can select these three items from the frond plannel control switch of the amplifier.

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.

Blinking light on front of amplifier Technics SU-V10X

Blingking Light usually means that there is DC appearing in output stage and is protecting Connected Speakers.
It can be faulty Output Stage (Bad ICs/Transistors/Resistors/Capacitors) or Faulty Power Supply.

Working on These types of Problem is not user friendly at all.

Advising to take local Authorized Shop.
