I have a sony d303 which is skipping quite a bit, i am going to adjust the
tracking gain but is it the screws around the laser that you remove

Thanks in advance for any advice

Has someone come up with a D555 service manual, and if so possibly recommend a source? I noticed that on page 1 of this thread vwap mentioned the possibility of acquiring one. I've held onto my old D555, which I stopped using when its mistracking became nearly constant. It had its laser replaced once, but everything else seemed in good order (never tried the line out) and I never pursued restoring it until now. Don't know if I'm up to tackling it myself, but I can start with getting the SM. Also, having K501 phones now, good cables, and improving amps it certainly seems worth revisiting the old standby.

hi all,

i've just bought a "broken" d311. it has the following problems: according to the seller, it makes noises when searching the next track and it can't play cd-r's. is this a pot-problem? and are those pots the same as the d303,d555,etc.?

I there anyone who does repairs on Sony D-25. If I can't get this fixed, I may have to buy an I-river Slimx 450 or 550.

Here's the prob. after inserting and playing the CD, the lcd lights up, disc spins, then after a few seconds, the lcd displays NO DISC and then after a while the cd stops spinning.

Tried tilting the player on different angles and on flat surface, still the same problem. What could be the cause? any suggestions on how to repair it or what to check on the player. Thanks in advance.

Bad laser? Worn out spindle motor? Contact local Sony service center.

I just sent the D-E705 to Sony Service Center for checkup/repair today. Will get back 2-3 days. I hope they would not reply no service parts available because its an old model. Thanks.

Hi All, I just aquired a Sony D-242CK Discman from a neighbour with the comment that it didn't work. On evaluation, the unit demostrated the following symptoms:

- High frequency of not mounting CDs or CDRs with auto shutdown.
- Badly skipping throughout CD if it mounted at all.
- Improved function when held vertical as compared to flat.
- ESP on, made things worse.
- Performance on inner tracks was worse than outer tracks.

Troubleshooting:

- Cleaned lens (alcohol) with no improvement.
- Cleaned/lubed (silicone grease) worm screw and rail. Some improvement to mounting frequency and skipping.
- Spray lubed (liquid wrench with teflon) spindle motor. Minor additional improvement.
- Soldered a permanent quick connect jumper socket to the test terminals. Could not get unit to enter test mode.
-Adjusted RV501 (metal pot type - tracking gain???). Unit now always mounts CDs/CDRs with some minor sensitivity to skipping on track 1 only (10-20% of the time). ESP on and unit lying flat seem to continue to make it more sensitive to track 1 skipping. Otherwise, the unit is now useable.

Help requests:

- Does anyone have a service manual for this or a similar model? Three metal pots, excluding laser power adjustment.
- Can anyone confirm the function of RV501?
- Does anyone understand why the unit will not enter service/test mode (i.e. low voltage, etc.)?

All feedback would be greatly appreciated!!!

Got the unit already. Repair cost is $35 usd for lens replacement. Not bad. Thanks to all who replied.
