  1. I have a Sony MZ-R501, whilst playing the drive stops after a random length of time, a constant whirling sound occurs, play resumes after a random length of time. This fault also occurs when I press track forward. I have done a video of this. During the last few years the fault has got worse, the player has been used occasionally. The fault is less likely to occur when the player is warm, say being in the sun.
  2. Sorry, the fault is less likely to occur when the player is warm.

  4. I have now found what the cause of the high pitch noise was, one end of a wire spring under the spindle was lose and touching the spindle rim, I clipped the wire spring end back under the plastic arm that should of been holding it. The ticking noise could be less now perhaps, see video. I could try to adjust the focus bias using the SM, is there a risk I could make things far worse though, basically is it fool proof?

  5. Thanks for the detailed advice. I have cleared the high pitch noise, this was really only by chance. What I did was touch the spindle hub rim with a watch makers screwdriver and turned the spindle a bit, whilst being careful not to touch the laser or anything else electronic. I also put a thin strip of adhesive paper on the plastic rim of an md (this is the rim that sits on the spindle hub rim), the drive though was not able to read the disc so I quickly pressed eject. The high pitch noise has gone then, hopefully for a very long time. As for the ticking noise, this appears to be very tr
  6. I have attached a video. The disc is a TDK rxg, this has the ticking noise that I always get on all mds and the high pitch noise that is unbearable. nearly all of my mds are TDK rxg, about 70% of them end up emitting the high pitch noise after a short while of playing them, occasionally when the noise is really bad playing briefly stops then starts again. you will notice I have put a bit of white silicone grease on the upper cogs IMG_0011.MOV
  7. The high pitch noise occurs on half of my mds. I took the unit cover off and listened closely to the disc mechanism whilst playing. The noise comes from either the motor in the top right corner of the mecharism or the wheel that holds the disc. Does the motor in the top right corner drive the wheel that holds the disc, as I cannot see any cogs or belts, perhaps they are underneath. Sounds like something needs a touch of silicone grease.
  8. The noise occurs during playing and recording, the high pitch squeeling noise is like the squeal of a car fan belt, but not as loud obviously. If I remove the drive cover and observe whilst playing, is this safe due to laser being used?
  9. The noise is deifinitely from the drive itself, not the audio. Disabling NetMD has no effect. The discs do not get hot. I will remove disc cover this weekend.
  10. I have a Sony JB980, when playing md's there is a high pitch noise. When a disc is spinning I can hear a constant fast ticking noise, on some discs there is a high pitch squeeling noise on top of the ticking noise. I successfully replaced the loading mechanism belt in August, but the noise did not start until October.
  11. I have successfully fixed the 980 player. With the drive taken out of the player I removed the top part of the drive (that hinges at the front) and re-connected to the player, I switched on power and the player stayed on. The drive was able to re-align itself. I removed the drive, put the top back on and re-connected. The player is now fully functionally. Thanks sfbp for the advice. I have a separate question, is this sony mds JB980 the best player that was made or is there an even better player, I could try to get this as a back up?
  12. I have the MDS 980. I put the belt on carefully, but I could ppossibly of broke something when I first tried to pull out a disc. My only hope is that the mechanism is stuck in the eject phase and that somehow I need to reset it.
  13. I have Sony MDS JB980 that is stuck on standby mode. The fault is with the loading mechanism, every few seconds the motor & front pully turn a tiny bit then turn quickly back. I am unable to load a disc. If I switch the power off I can manually push the disc in, when I switch the power on the mechanism ejects the disc. The error code history is 10,50,10,50,10,50,10,50,10,51 10 is loading error The first problem I had was that the mechanism did not eject a disc. I replaced the front pulley belt, the original belt was broken. Does anyone know how I
