Need 1984 SONY CDP 701 ES repaired

There is a red LED that indicates the player does not recognize the disc is there

Just throwing this out there, but is the disk a normal one and not a cd-r or SACD ?

If you plan on keeping the player, have you thought or tried to contact Sony ?

3 reasons to scrap it:
1-the cost of a repair will probably be more than buying a used ES 15-20 years newer.
2-DAC's have come a long way in 25 years. You won't believe the difference.
3-How long until something else goes?

Sony's are nice but 25 year old cd players of any brand aren't worth fixing.

I'm with Elevick; it's truly not worth trying to repair it. And I seriously doubt there are many older CD players that are "collector's items". Maybe a California Audio Labs Tempest, but that's pushing it.

My advice is to simply replace it with a used Sony, Denon, Music Hall, NAD, Jolida, Rotel or the like that's a more recent vintage. I think you're going to see a very significant improvement in the sound.

Some, if not all, CD players from that era typically do not recognize the first and last track of modern CD's. Try selecting Track 2 and see if that works.

As others have stated, a 25 year old CD player really doesn't have any intrinsic value regardless of its pristine condition.

Digital to Analog (DAC) technology has improved tremendously. The DAC used in the CDP 701ES can't compare to even mid-range CD players manufactured today, in terms of audio reproduction.

Let it go and buy new on the edge of the curve, e. g. Oppo 83SE.
