Question about SanDisk SDMX1 MP3 Player

Opening Case for Repair, Defective Head Phone Port

The headphone port on my SDMX1 appears defective. It works intermitently on the left side only when the plug is at a certain angle and tilted that way. It does the same thing with new head phones. It has been suggested on this board that it can be repaired by resoldering. I can do this and other possible repairs to the metal contacts, but I can't figure out how to open the case. The only instructions on this board: "remove the battery, slide the plate down, and pop open the case" aren't good enough. What plate? Where does the case pop open? Please give me very specific instructions. With a $50 replacement cost I have very little to lose trying this repair.

    Thank you nyxseraph for your solution. I am sitting here listening to continuous Beethoven music on my repaired SDMX1! For others that try this I offer a few more details. You have to remove the screws on the two ends before you can slide down the two end plates. Down means the direction away from the rounded edges of the end plates. The soldered connection on the outside edge of the headphone port was broken. I could see it move as I plugged in the headphone plug. The connection is very small and you may need a magnifying glass to see it. The break appears to be due to stress put on this joint as the plug is moved around. I resoldered the joint by heating a heavy paper clip to bright orange red hot in a gas flame and quickly put the end onto the joint. I kept pressing on the joint until the clip end cooled.

I had the same problem with my SanDisk SDMX1 player. After you remove the battery you can slide down the two plastic endcaps of the MP3 player shell (one end has the headphones and microphone and the other end has the usb input). After you slide both of them off the player can be pulled apart into the two peices of the outer shell and the internal "guts." The spot to resolder was hard to get to with a conventional soldering iron. Since I didn't have one I just heated up a paper clip tip on the stove to red hot and pressed it to the area that needed soldering and rubbed on the solder. My MP3 player now works fine (I was amazed it worked) If you need more detail please ask.

NO sound on portable DVD player after plugging headphone


One of two situations: Plugged in headsets connect to contacts inside of the female port on the player. If any of the internal connections within the female port are shorted the player switching component will not disconnect and thus the player speakers will not function. Could be dirt, metal particles from the surface of the head phone pins, or just a defective female jack. You may try to insert a small round probe (like a tooth pic etc.) saturated with rubbing alcohol and twirl the probe around to collect any deposits off of the integral connectors. Be careful Not to break the probe off inside of the port. If after this attempt the same problems exist; only a qualified technician can observe the interior of the player for electrical disfunction.

My phone wont charge


The phone is not charging because:

1. The charger of the phone maybe bad. Test the phone with another charger or test the charger with another phone to confirm if the charger is defective or not.

2. The charging port of the phone maybe defective. In this case, the charging port needs to be replaced.

Good luck.

Please help - my phone won't charge at all when i plug charger in (i have 2 chargers and neither works), however the headphones work perfectly. what is the problem ? thanks - avril


Hello,

The charging port of your phone should be the cause of the problem. It's either the charger is not contacting the charging port well enough or the charging port might be defective and needs to be replaced.

Use a pin to scratch the surface of the charging port and try again. If that doesn't work, then know for sure that you will have to replace the charging port.

If you feel you can do the replacement yourself let me know when you get a charging port replacement so that I can direct you.

Good luck.

The Right side does not work.


i just bought the turtle beach x1's and had the same problem only it was the left side not the right and i was pushing the green audio connector cable to close together with the av componet connector and just slightly removed the audio cable from the av connector cable basically just slightly remove the headphones from the connection port on whatever you are connecting it to if that dosent work then most likely you have a lose connetion port on your device and will need to replace it or replace the device alltogether if the port can not be replaced.

No its not defective. If you use your usb modem, plug it in to a working port. It is the default or home port of the usb modem since it was installed on your system. If you use other port for it then it will not work.
