My beloved Marantz DV4100ose has started 'sticking' on playback of any discs. It's not a dirty lens.
I have some friends coming over this weekend and we want to watch a film and have a little music, so I'm contemplating buying a really cheap DVD player from the supermarket or big name electrical shop. Has anybody any recommendations or otherwise? Cheers
PS Anybody that can help with the Marantz problem please do as well :) |

What do you mean by 'sticking'?
There's a common problem with some CD/DVD mechanics: the lubricant applied to the metal guides that hold the laser mechanism dry out and become 'sticky', making it 'jump' when reading a disk, or even stop playing in the middle of a track.
Clean all the residues from the metal guides and apply new lubricant, in small quantity.
For years I've been having excellent results with a very viscous lubricant that seems to last forever in this role: STP car engine oil additive.
:D |

| The symptom is that the track just pauses as if the pause button has been pressed, then starts again after a random few seconds. Thank you Carlos, I will open it up again and see if re-lubricating is required. |

they are so cheap this days that it is a crime trying to fix one. I got a DVD recorder / Tivo, with 3:2 pull down, progressive scan, wireless connectivity, usb/ethernet, etc., for just $100.
I have a couple of those super-cheap supermarket dvd players that I picked up from garbage. they seem to be fine. both play CDs / DVD fines. one of them does seem to have trouble with mp3 disks (the other cannot): it seems to have some sort of AGC problem and fairly noticeable distortion.
But it plays pretty much any kind of disks and files you throw at it. |

| Yeah, I'v got a $49 Apex like that. It has survived a few years of abuse from Red Chief. |

| I have an Apex I bought at Sears for $29 and got a $5 rebate in the bargain. It seems to work. |

I want to fix my Marantz because it looks a darn sight better than any cheap player and matches the rest of my equipment. I'm sure it must have better picture and sound quality than a cheapo as well.
I'm going to take the lid off now and see if I can see these rails that Carlos is on about. |

| OK, I've done the cleanup and re-lube and now it's worse than ever :( Would I have damaged anything by sliding the laser pickup along the rails to gain access to the whole rails? |

What did you apply there?
What kind of lubricant?
It can get worse depending on what you put there.
But hey, seems that the problem is right there. |

The mech seemed fairly free, but I could see a smearing on the rails of what I presume to be a silicone dry lube. I first cleaned the rails down with WD40 on a cotton bud, then with IPA on a cotton bud (q-tip). Then wiped all over with a clean cotton bud and applied a few drops of some micro oil that I have which is supposedly great for sewing machines etc. I then slid the assembly back and forth a few times to work the oil all over.
I've just been back to the player and now it won't even read a disc. Could I have damaged the lens by wiping it over with a bit of IPA on a cotton bud? |

You did the thing well, but that oil gets sticky, don't use that thing here!
I've been there...
Seriously, go and get a small can of STP oil treatment for car engines, it works very well. |

The micro oil is a special oil that does not get sticky or dry out/gum up. The makers also make a car engine friction reducer based on the same chemistry, that I put in my car engine.
Besides, it would not cause a problem straightaway anyway, would it? |

| Try running it for a while with the lid off, and see if that helps. I have had issues with several of these cheaper players overheating slightly. |

| I damaged a gear (broke a tooth off) when I attempted similar surgery a while ago, by forcing the sled along its rails. That was it; just wouldn't track after that. I hope this warning didn't come too late:cannotbe: |

LOL I wouldn't call £400 retail cheap. Less haste Al ;)

Hmm, I didn't force anything -- it seemed to move quite freely. I've just tried it again after wiping down the rails again in case there was excess lube, and it played for about a minute this time. So I guess it can't be a broken gear. |

Richie, I gave you my advice based on my experience.
There are special silicone-based lubricants to apply on that kind of gear. Even that can fail after a couple of years.
I had a problem with a Yamaha CDP years ago and I applied several kinds of oil, some lasted for a week, some didn't work at all, some lasted for a couple of months and then the player started skipping again.
I guarantee you that sewing machine oil doesn't work at all.
Then something hit me and I had the idea to try STP oil treatment, which is very viscous, doesn't dry out, holds on to the metal parts and makes them run smoothly.
This was some 4~5 years ago and the player still works (on a secondary system) as new.
I have since applied STP on CDP (and even CDROM) mechanisms, and the results are always a smooth-running transport. And it lasts loooooong. |

| :D thanx for the tip carlos , l have an older denon cdp that l picked up s/h that does the same thing starts off beautifully then goes all over the place, thought for a while that the laser might be gone, thats why l havent touched it for a couple of years, might try your cure as l suspected it might be something like this.... :smash: cheersTC:D |

| OK thanks Carlos, but the stuff I used isn't exactly sewing machine oil -- that's just one of the many uses of it. From your description of the STP stuff, this does exactly the same thing. I may get some STP, but I'm just getting fed up with it now :( |
