How do I open/disassemble my env3 so I can reconnect the heacphone jack? it only plays through one headphone unless I wiggle and put pressure on the jack, then it plays through both earbuds (I know it's not my headphones).

If the wires can be joined see the attached pics for re-joining, just connect the same colours together. Test them to make sure there are no other breaks in the wire. Then solder them together and seal with a waterproof tape or similar. DONT just tape them together this will lead to them coming apart easily.

If they came out of the jack it would be best if you bought a new jack and soldered the wires onto this. Trying to open a factory fitted jack is difficult and you wont be able to seal again properly unless you superglue the jack once you've reconnected it and test them to make sure there are no other breaks in the wire solder the wires to the jack. see attached pics for jack wiring.

Hope this helps

Step 1:
Your trusty iPod has been a close and reliable friend for a long time but one morning only the sound of air comes through the headphones. The likely culprit is a loose or broken headphone jack that is in need of repair. Rather than spend an exorbitant amount of money to have someone fix it you can easily make the repair on your own and have your iPod friend back. Read on to learn how to fix a broken headphone jack for a fifth generation 30GB or 60GB iPod video.

Open the iPod case with a small flathead screwdriver by slipping it under the centerline of the case. You will find a series of clips you have to release in order for the case to open up about an inch. Locate the headphone jack connection and verify that there are no broken wires. Fix broken wires quickly by twisting the wires back together and wrapping with electrical tape. Test the iPod for sound by connecting your headphones to the jack. Replace the wires completely if you find static coming from the iPod jack. Fold a business card twice so that it wants to unfold and slip it into the case over the blue sponge. This creates the pressure needed to hold the jack in place and allow a solid connection. Push the case together without engaging the clips on the side and test to make sure the jack is now working. Try a thicker business card or fold the first one again to get enough pressure onto the jack connection if the first card didn't fix the problem. Press the case fully together until the clips click into place. Use extra care when inserting your headset to ensure the jack remains in place.

Seems that you forgot to reconnect the internal speakers to their dedicated connection on the motherboard. In order to fix this, you will need to disassemble the laptop again & reconnect these wires.

Did you check with other headphone?

I suggest you take them back to the shop and see what they say, hope you kept the recit! Otherwise contact Skullcanday. Don't attemp to fix it yourself or you won't get your money back or any replacement, as you should under law.

The "Breath" jack is for a "Breath controller" NOT headphones!!!

The breath controller was a pressure sensitve device you blow into that generates a signal to modulate the sound.

Put the headphones in the jack "PHONES"
I know, I have an SY77.

Your jack is probably loose, the only solution is to reconnect, or solder it.

First try the headphones in a different machine, such as an mp3 player or cd player to make sure the headphones still work.

Try going to the start button, then settings and control panel. Then select "Sounds and Audio devices" Down at the bottom you should see "Speaker settings." Click the "Advanced" button and then select stereo headphones.

Then, place the headphones into the green audio jack (or the headphone jack up front if you have them), play some music, and then gently wiggle the jack to see if some of the sound makes it into the headphones. If not, try slowly pulling the headphones out of the jack while the music is plaaying. you might find that the jack has slipped a little and may play only if your connector is slightly pulled out or more firmly pushed in. If his helps, then your audio connector is loose and you should replce the sound card. If the card is on the motherboard, you can disabled it when you put a new card in.

It is likely that your right stereo channel has either been severed somehow or there is a severe short in one of the cables. What you can try to do to test this theory is first turn on your music. Then wiggle the cable at the very base of the right earbud. If nothing happens wiggle the cord right where it connects to the stereo jack. If still nothing happens run your fingers along the right earbud audio cable bending and twisting it. If at any point you hear music again then you likely have a short. If it is near the earbud then it is going to be difficult to fix since these earbudfs have a large gauard. If the short is at the stereo jack then the fix is simple. A standard 1/8" stereo jack can be purchased from any electronics or audio store. You can then fairly easily seperate teh old stereo jack and solder this new one in place. Search the internet for tutorials on how to do this if need be. Even if you do not get any kind of sound when wiggling it at the base of the jack this is the most likely culprit since this is where most of the stress on the headphones occur. Be wary though, if you do attempt a stereo jack repair you will void whatever kind of warranty your earbuds may have so check before you try. But, in teh end you may end up saving a 60-100 dollar set of earbuds for 5-8 dollars. Hope this helped.

I too had a problem with the headphone jack. It took me a while, and a few scratches on my Sansa C140 case, but I FINALLY figured out how to seperate the case.
1) POP the black top (with the buttons and display cover) off. Get under the edge and pry, working your way around. It's just snapped on.
2) With that cover off, you will see four (4) screws, one on each corner. Remove these. The BOTTOM will now come off (may require a little wiggling to slip the battery terminals out of their grooves).
3) You should now be left with the main board contained within the middle of the plastic case. Removing the board is a CHALLENGE as it is held (not tightly) by a couple of tabs, as well as the headphone jack and the connection port.

Be careful when working to get the board free. I ended up popping two of the solder-tabs off the board for the headphone jack when "prying" the board out of the case. Luckily I was able to fix it when re-soldering the jack to the board. And one of these may have already bad (requiring the repair in the first place).

Reverse the steps to put it back together, again being careful when re-inserting the board back into the casing.

Good luck. Hope this answer still find you in time...
