GPX HMTU3234 Shelf System Questions & Answers
The CD player does not work
It sounds like a mis-aligned laser or faulty laser unit. Either way unless you have experience of fixings cd players yourself its a job for the technicians. Good luck.

Motor speed needs to be regulated by PWM. Reducing the current (with a resistor) actually lowers the torque - which, with a given load, does result in reduced speed - however, different length tapes (60min vs 90min), as well as different quality, and even current position in the tape, will change the load and hence the speed.
You need to regulate the speed via PWM. It's sometimes done on a small board built into the motor, in which case you'd have a round hole into which you could insert an INSULATED screwdriver (tiny flathead wrapped most of the way in electrical tape works).
It may be done on the main board, in which case you could find a pot conveniently labeled "motor speed", or perhaps "pulse width" or "pwm" or something to that effect. Find it, mark its current position just in case, and turn it to see if it gets the effect you're after.
And there are some tape decks in the world with no speed adjust - they are designed with a specific speed motor and the sizes of the wheels and gears are calculated for that speed.
Also there may be a mechanical fault/malfunction causing the speed problem.
An initial check and thorough cleaning of the capstan and pinch roller should be done. If there is a buildup of tape oxide or a piece of a broken tape wrapped around the capstan, the tape travel will be too fast (do to the effective increase in capstan shaft diameter).
If the pinch roller isn't fully engaging, the tape can be getting pulled onto the takeup spool at a speed faster than the capstan control.
A different source of trouble might be a slip clutch (possibly an
idler/clutch assembly)which is binding, or otherwise not functioning the way it should.
Another type of motor doesn't have it's speed controlled by an internal or external voltage.. instead, the motor has an internal centrifugal speed controller. This type of motor can be found on older tape decks, and might not have been utilized more recently.
Good luck
On my gpx cd home music system HM38170T the cd door won't open. How do I fix it?
If the CD door on your GPX CD home music system HM38170T won't open, here are a few steps you can take to troubleshoot the issue:
- Check for obstructions: Make sure there is nothing blocking the CD door or the area around it. Sometimes small objects or debris can get stuck and prevent the door from opening. If you see any obstructions, carefully remove them.
- Power cycle the system: Turn off the system and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on. Sometimes power cycling can help reset the system and fix any issues.

My gpx mw240s says error and i cannot play any music. What else should i try doing?
If your GPX MW240S MP3 player is displaying an error message and not playing any music, there are a few things you can try to fix the issue:
- Reset the player: Sometimes resetting the MP3 player can fix the error. To reset the GPX MW240S, press and hold the power button for 10 seconds, release the button, and then turn the player back on.
- Check the music files: Ensure that the music files you are trying to play are in a compatible format with the GPX MW240S. The player supports MP3 and WMA formats, and if your files are in a different format, they will not play. You can convert the files using a free online converter.
- Update the firmware: If the player's firmware is outdated, it may cause errors while playing music. You can update the firmware by downloading the latest version from the GPX website and following the instructions.
- Check the storage space: If the MP3 player's memory is full, it may cause errors. Delete some files from the player to free up space.
If none of these solutions work, there may be a hardware issue with the player, and it may need to be repaired or replaced.

Brand new GPX mp3 player will not pair or show up on usb drive
Instruct the computer to search for it. The computer should automatically find it and load drivers, but it should show in Windows Explorer as a volume in the left pane. Where are you looking?
It will only pair with a computer if the computer has Bluetooth and most don't. Pair with a smartphone.
How do I transfer my music to my device?
This device is capable of playing MP3 and WMA (4ithout DRM) files. To load files requires a computer with a USB connection and the minimum requirements of Windows XP .
- Connect the player to the USB cable provided in packaging, and then connect the other end to your computers USB port.
- Once connection has been made between the device and your computer, a "GPX" drive will appear in the computer directory.
- Double click on the GPX drive
- Drag and drop your MP3 files and folders into the Music or playlist folder

Gpx s7050 cd open/close button not working. is there a fix?
Sometimes there's a small pinhole in the face of the door panel. If so, straighten a paper clip and press straight into the hole. That will press lever that pushes the slide outward. If no pinhole, try a case knife (table knife). Shove between the door panel and the casing, and try to pry it panel outward.
Once, not too long ago a friend lost a CD. They were sure they put it into the player on the laptop. When removing the CD player, I found the CD laying atop the player casing, so either they shoved it in the crease between the player and the laptop casing, or it popped up as they were closing the door ind it was shoved int hat crease.
Good luck.
