I have a 1986 vintage Technics component system that has been boxed up for years and I can't remember how the equalizer is hooked into the system. The manuals have been misplaced. How is the equalizer wired to what other component or components? All of the components are the same brand, Technics, and were a matched system. The Amp is MDL# SU-V95-KM5, the Cassette Deck is MDL# RS-T25-KM, the Equalizer is MDL# SH-8029-KM, the CD Player is MDL# SL-P105 and the Tuner is MDL# ST-S75

Question edited for clarity.
Question moved to a Technics Equalizer category.

Failed components inside is the only answer without testing. Open it up and look for circuit board damage or blown capacitors. In reality, you need to take it to a service centre where they have the test equipment and knowledge.

These have been around at least since 2011. I can't even find Technics support page. I gather one might dig out the address for support from one of the manuals. But I can't find its manual, either, just one for the SH-8058. You might get some 3rd party support from a n appropriate forum in Tom's Hardware website. I've seen pages advertising this model used for shockingly low price or about $200. And a YouTube that may be in Spanish. So, Ill list some of all that but can only wish you good luck in chasing down a hobbyist site for this vintage setup. https://forums.tomshardware.com/threads/help-with-connecting-80s-technics-audio-components.3579784/

Doesn't matter what order the 3.5mm are wired up in. As long as one connects to another in a daisy chain, data will jump from one to the other to give remote operation or auto source changing

I would use the s-video out & red & white rca audio out on dish box to s- video & audio in on the t.v., then audio out from t.v.(RCA, red & white) to one of the inputs (RCA) on the receiver.

Yes, it is a little tricky...

1) CD Changer (output) -> CD input on Amp

this is tricky... this will allow you to record to your tape deck, and control the sound via the EQ:
2) Tape Deck (tape out / recout) -> TAPE PLAYBACK on EQ
3) Tape RecOut on EQ -> Tape 1 Playback on Amp
4) Amp Tape 1 RecOut -> Tape Deck Playback / Input / RecIn
in essence, your creating a loop starting from the tape deck, going to the eq, then to the amp, then back to the tape deck to record.

Your EQ has another set of LINE IN and LINE OUT - use the second Tape 2 on the amp to create another loop. This will
allow you to control the EQ for any of the other sources.
5) LINE IN on EQ -> Tape 2 RecOut
6) Tape 2 Playback on Amp -> LINE OUT on EQ

5) Radio Tuner (output) -> Tuner input on Amp
6) DVD/VCR Combo Output -> AV/AUX on Amp

7) PC Computer... you don't have room for this. You can either use the PHONO input, and you'll have to purchase a Line Level Phono Converter
or, get a Y cable and split the signal and share with some other source.

Hope this helps.

the Technics SH-8058 is a beautiful unit, I got one myself for the past 20 years and never failed y EQuing the sound I want.

I am asuming, you got on your reciever TAPE MONITOR... well, the it is simple,

First, just forget about the TAPE on your Techincs SH 5058

Second, on your Technics LINE OUT, goes on your tape monitor LINE IN

and last; on your LINE IN, goes on your tape monitor REC OUT.

Now, choose you desire componet, and turn on your TAPE MONITOR on your reciever...

enjoy and have fun.
