Can I Repair These Iconic Portable CD Players?

[@azliwinchester2100]

I still use discman. I use it with my 90's Panasonic and 80's Sanyo boombox that have a line-in. I prefer a discman that have no button on the top. The less button are better for me.

Lovely! I will get around to pulling them apart to see what's in side. I was saving them for a rainy day! I suspect they are very similar in electronics etc, its all about the design with Sony (although one seems to have a rechargeable battery inside). They sound amazing.

Dropped my one on the floor and the back spring is not closing properly can that be fixed 😭

[@GerrysTech]

Sounds like it can. By Spring, do you mean the battery terminal Spring?

got a samsung MCD-Mp67 that plays cd fine, but i get absolutely no audio. What is the problem?

[@GerrysTech]

When you say that it plays the CDs fine, do you get audio or it's only when it plays MP3 files that you don't get audio? Regardless the first thing I would do is pull it apart and have a look to see whether or not you can see any physical damaged to the headphone port or the traces especially around the battery compartment.

Upon further investigating I found out that the sound is coming through but very faintly even them then the vol dial is all the way up. Did not see any physical damage on the inside.

@@Cool_Hand_Luke77 Have you tried another pair of ear phones, just in case? Also cleaning out the headphone jack might help. Also, have you tried using the line out to connect it to an amplifier? I would also try contact cleaner in the headphone jack and volume control. Especially if when adjusting the volume it makes a scratchy sound. I think this is the manual www.manualslib.com/manual/144422/Samsung-Mcd-Mp67.html?form=MG0AV3

@ I have tried different headphones with same results. Seems like line out is dead. No sound at all. Volume dial doesn’t screech when turning. I noticed that there is an X marked on the board next to the volume dial, right on top of what seems like a diode. Is this normal for pcb to be marked? I really don’t want to throw this cd player out.

If the ex is written in pen, then that would be my first suspicion that somebody has opened it and discovered a problem. I would start poking around with a multimeter starting with the diode. I would also carefully check with a magnifying glass as much of the board as possible looking for broken traces dodgy soldering and components that look like they might've blown up.
