ZVM280 Aiwa combo unit

Is the repeat on?

Sorry but the control board is shot that's why there inexpensive to purchase they only last for 3 to 5 years

try crossing over your speaker wires , criss cross them from like A top and B bottom. then there ussally are 2 button that control the speaker out puts. Find the buttons and try pushing them in and out until u get sound. hope this helps

If you need further help, I’m available over the phone at https://www.6ya.com/expert/robert_e9d0abd7cc2508b3

does it come with remote

there is a small hole in the front panel, straighten out a paperclip and push one end into this hole until the tray releases.

Judging by my own experiences with hifi gear on eBay there is little on the face of the planet that ever really becomes UNavailable.

Wouldn't an attempt to resolve the issue work, too?

Describe your setup (preamp, amp, whatever) and if it has ever or never worked.

This unit can work through its own preamp with any audio equipment or with old-school gear already having an internal Phono Preamp. There's a switch to select which one.

Same model, same problem. (CX NA-50) I have one that worked great for two years (at best) and I haven't used it since then. I recently decided to look for a solution via the internet.
I read somewhere else that there was a class action settlement with aiwa (now expired) since many of these units had this problem. 

I thought that I had the same problem. I then discovered that when I put 3 CD's in it started up on it's own. If you push the demo button you can see how it's supposed to light up the number of tracks in a square on the right of the display. It wasn't doing that until I put in all 3. Then it started up and I was able to use the disc 1, 2 & 3 buttons to change from 1 CD to the next and I used the Up and Down buttons to change songs and the play button above the tape deck is multi-functional. Hope this helps.

Maybe a problem of no power to motor. I own 2 identical Aiwa units, both have tape deck problems. This brand is prone to them They also have nasty habit of tape cassette doors jamming.
1st off you never said how old the unit is. Awia have huge amount of models. Mine are the NX series that came out in black plastic. Most of the others are silver/grey. Honestly, unless you pop side screws and lift the cover off to eyeball anything loose. and none is? And if out of warrenty, the value of fix, mat exceed value of unit.
Sorry, but I see many of these,  of 4-5 yr old units Aiwa brand,
get the heave ho! 
The most stupid thing about this is: for units size, has the best sound of any other brand it's size.. Brilliant for hooking to ones TV sets, for  surround sound!
What I did was get an older getto blaster  that plays tapes to play my tapes on. some of these units are around and in good order, dirt cheap. And most electronic equipment problems cost at least $35  just to have a quick look at your unit.. cost of repair on top?  I brought my 1st one new @ well over a grond. 3 yrs later, 2ns one, exactly the same $15.00 in a charity shop. The  laser unit was dusty. All go in half an hr. Perhaps if it is an older model , look for another mate to it,   It all comes down to costs.
Which is better option... you are the one who has to made the choice. Good luck. Jamz

check the laser eye of your player clean or replace.
