Radio on my sony rx d7 hi fi 3 cd changer

Yes, Sandra, you need to plug this CD player into a tuner. Almost any tuner will work. Using a red & white audio cord (and any cords with similar plugs), connect the Line Out from the CD player to the Line In on the tuner. Depending on the tuner, you may have Line In inputs for CD player, AUX, and possibly others. Any of them should work.

If you don't have a manual for the player, you can download one from the Sony support web site at :
50 Disc CD Changer

You need to have the fan in the check,possibly its not working anylonger

Visit the on-line store, known as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem. Best Manuals

Is there a transit screw in the bottom? It (they) need removing.

If you hear a little motor straining to open the tray when the open button is pressed, there is something jamming it. In a new machine, there are usually transit screws.

Read the manual, looking for unpacking instructions.

I would have thought that it should go from the amp to the tuner,then the tape deck and finally the CD deck.

I'm suspecting that your tuner is faulty and thats whats causing the system to shut down

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 CD player muigt be able to rescue by a reset top factory settings, mostly available in your manual, the cassette deck i think needs to be repaired.

Unit probably has bad drive motor

If it havent been use for a long time try dusting it and cleaning it first, sometimes dirt gets stuck on vital places which makes it go crazy. Hope this works. Please dont forget your rating for me as well...We take time in answering problems. Thanks
