20 Most Recent GPX HMTU3234 Shelf System Questions & Answers


Hi,

I think that the rubber wheel pushing on the tape and controlling the speed is stuck somewhere and this preventing him to stay on the tape and control its speed

Actually, you start the turntable by moving the tone arm AWAY from the center.

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

Many online music stores employ DRM to restrict usage of music purchased and downloaded online. The best way to overcome this is to download DRM- free tracks. Some online music stores such as amazon, eMusic and Beatport give you DRM free tracks. Try getting your music from them. Or else you can rip the Cds to get the tracks.
hope this solves your problem.

FixYa!!

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.

Most of those types of screws only require a 1/2 turn to unlock.

What happens is that a mechanical system under the turntable pushes on a micro switch to operate the motor. Clearly either the mechanical system has moved out of position or the switch has. You take the bottom off the turntable and see what happens when you move the arm.

I searched and couldn't find a manual. I found a free manual for a different model GPX that might be of some use. https://gpx.com/amfilerating/file/download/file_id/83242/ https://gpx.com/amfilerating/file/download/file_id/83242
