Sony Walkman NW-S705F Loose Earphone Fix




Introduction: Sony Walkman NW-S705F Loose Earphone Fix

After some time, some NW-S705F players sporadically have very low volume, crackly sound or even no sound at all. Sony will repair these under warranty, but if it's out of warranty, you're out of luck! So here's my first instructable on how to fix this problem.

You'll need one star jeweller's screwdriver and two flat jeweller's screwdrivers.

Please bear in mind that following these steps *will* invalidate any warrantees, guarantees or any other promises/agreements relating to the device. You are also quite likely to break the device, set your house on fire and howl at the moon in frustration. If you find all of this acceptable, please carry on!''

Step 1: Remove the Hold Slider

Remove the hold slider by gently pushing a flat-head screwdriver under the left-hand side of the slider. It should pop out quite easily - if not, you're doing the wrong thing - try a little closer to the middle.

Step 2: Remove the Front Cover Screw

Remove the small screw just under where the slider was. Be careful - if you drop it, you'll never find it again!

Step 3: Remove Front Cover

Now remove the front cover. It is held in place by a small piece of double-sided tape under the cover on the left hand-side. Push a flat-headed screwdriver under the cover on the right-hand-side.

Step 4: Remove Board Cover Screws

Remove the two board cover screws, using a star-screwdriver.

Step 5: Remove Board Cover

Remove the board cover, by sliding a flat-head screwdriver under the right-hand side of the cover.

Step 6: Remove Top Board Screws

Remove the two top board screws

Step 7: Remove Top Board

Remove the flat LCD ribbon cable. This is quite difficult and it's important to avoid ripping the ribbon cable - if you do, the LCD will stop working''. I used a small flat-head screwdriver to push the tabs on the side of the cable away from the connector, This is more difficult than it should be, so I suspect that there is a better way to do this.

Once the ribbon cable has been removed, pull the right-hand side of the top board gently towards you using a flat-head screwdriver. This will pop a connector on the underside of the top board out of a small socket on the bottom board. Gently lift the right-hand side of the top board up over the lip of the headphone connector and then you can gently slide out the top board towards the right-hand-side, bearing in mind that the charge/data connector is quite tightly fitted in the case. Also, be very careful that the battery cable on the underside of the board doesn't snap - remove the top board and the battery at the same time.

Step 8: Remove Bottom Board Screws

Remove all of the screws on the bottom board. Remove the board spacer as well

Step 9: Remove the Bottom Board

Gently move the sticky edges of the foam backing under the LCD ribbon cable away from the bottom board. Then gently manipulate the LCD ribbon cable until it is completely under the bottom board. Remember that folding, bending or ripping the cable means that the LCD will stop working! So please be careful.

Remove the headphone jack ribbon cable by lifting the black tab on the connector and gently pulling out the cable. As with the LCD cable, folding, bending or ripping this cable means that it will stop working!

You can now remove the bottom board, bearing in mind that there is a small piece of double-sided tape holding the one side down - gently remove this.

Now is a great time to find out how many screws you have lost. They're tiny and for some reason very prone to bouncing away. ;)

Step 10: Fixing the Problem

The whole reason that you're here is to find out how to fix your headphone jack problem ...

It's entirely possible that by disassembling and then reassembling the device, you problem will go away! This is because the headphone jack connector/cable seems to oxidise ('rust') and removing the cable causes most of this 'rust' to be removed. This is what caused my issues.

I fixed the problem by gently scraping off the 'rust' with a flat-head screwdriver. It's a _very_ tiny connector and even with a magnifying glass, I struggled to see what I was doing.

The alternative is that the headphone jack itself has broken. I spent an hour or two trying to disassemble the headphone jack and didn't get anywhere, so if anyone has some hints, please drop them ;)



Step 11: Putting It Back Together

Well, now it's time to see if you broke anything while taking it apart. :D

It's quite simple to put back together - just follow the steps in reverse - nothing complicated.

Enjoy and good luck!

I did what elgojoe did even before reading his comment. No need to even touch the video cable. So nice of you to put together this guide and omit the battery -- which is the part I needed to replace. But it worked out anyway. It turns out there is only one way the battery cable wants to go in. A magnetic tray for the screws should be considered mandatory for this project. Anyway, thanks.

Thanks for the guide - it was a great help and got me started. You are correct in your suspicion at step 7 - there is an easier way to unplug that ribbon cable! In fact it is a ZIF or LIF socket but to get to the unclamping lever you need to lift off the small board with the large chip (that takes up almost the whole board) that sits right on top of everything. This board lifts off by unplugging very easily indeed and then you can see the entire ribbon cable socket. The long black back edge of the socket simply flips up after which it is very easy to unplug the ribbon cable.

Very good.
Three comments:
- You do not need to take off the ribbon cable of the display in step7. You can slide from left to right the top boards. You will need to force a little bit to help the USB connect to slide out of the main metal frame of the player. To put it back later-on put just slide the USB connector first at its place (and force a little bit again) and then the top board should follow.
- When the player was put back together it did not work at first (dead like!). I had to plug it back in the PC with the USB cable to make it to restart...

I love that player even more since I started to use the open-source software JSymphonic. I stored it on the player itself and because it is a JAVA program it run on any computer without install. Great stuff!!

Thanks a lot again for the advices!

Thanks for the guide. After I had mine repaired twice by Sony (for free, fortunately) I thought I'd give it a go myself the 3rd time the sound started to crackle. I only disassembled it up to before the display cable and put it back together because I got scared, but it seems I fixed it anyway :)
