Hi jadis,

CD lenses do die. I first encountered this when the Philips player I used as a transport for the Wadia would not play. Mario, the one who maintains my system, told me the lens had died. He also told me that replacement lenses comes in different qualities that determines the service life of the lens. I think your transport is a McCormack modified Philips player, and I think Mario can easily change the lens for you if it is really the cause of your the problem you are encountering.

Hi jadis,

I just realized that you encountered the problem in 2005. It was the first time that I saw this topic and I presumed that it was a recent post. My apologies.

No problem, Mullard. And thanks for the input. I seldom use the CD player nowaways but it's good to know Mario can fix the problem when it needs be.

if its a philips, pioneer and sony transport/lens, its very easy to find a replacement. A friend of mine had a Philips 89' (forgot the model) cd player, got a replacement lens sa deeco and just cost us Php 350 Sony medyo mahal, mahirap Yamaha, Denon etc.

With Sony, the lens cdp mechanism may be common with their dvd players so it is possible to find a replacement.

I am having some problems with Marantz. They used to be owned by Philips but has been sold. I've got a Maratntz sacd/cd player that needs lens replacement. Anybody knows where to have this serviced?

TIA.

recently resurrected a Philips discman, at first it wouldn't read the CD. then consecutive trials (and wiping the lens with a cotton bud) led to it recognizing that there's a cd inside until finally it started playing.

i figure it needs a little lubrication on the rail where the lens runs, what would be safe to use? (i once had my sony playstation serviced and the tech used some white stuff on the rails)

thanks

Sometimes, skipping or unable to read disc is just caused by a dirty lens or gears and rails. Kung minsan natutuyo ang grease causing the laser mechanism to get stuck at a certain position in the railing. Ito and sakit ng Micromega CD Player dahil the transport that was used was the batch that was manufactured in Malaysia with the wrong type of grease.

All you need to do is clean/remove all grease and relube it. Also use a clean cotton bud (best dip in 100% alcohol) and very gently wipe the lens.

If all done above still doesn't work, then you might already have a dying or dead lens.

Just to add to the thread...

Two years ago the drawer on my Wadia wouldn't open so I contacted them about repairs and they also brought up the laser replacement.

This is part of the email I received:

One other thing to consider would be a laser replacement. The laser is something that will wear out over time and depending on use we find that lasers commonly last between 8 to 10 years.


:o

That time I thought he was just out to get more money from me but I guess they really do wear out over time.

Fast forward to today. I just sent my unit in finally to get fixed :lol: I asked about replacing the assembly while it's there kaya lang I was informed that they are trying to source better laser assemblies as the ones they got did not meet their specs. Hopefully I won't need a new assembly for now. I'll just send it back when it craps out :tmi:

Oh, they quoted me $400 including repair of the drawer, replacement of the laser assembly and return shipping with new boxes.

I have an old stage 3 micromega i'd like to ressurect. I've tried silicon lubrication and wiping the lens but had no success.
I would appreciate a referral to a reputable repair shop.
thanks.

The laser does sometimes die, but not nearly as often as a lot of people think. There are myriad other reasons why the cd may not be read properly, from dirt, to dried lubrication to dried out capacitors or other power supply problems.

I have posted this link before, but I do think it deserves another posting. http://www.lampizator.eu/LAMPIZATOR/TRA ... ology.html You can do some quick diagnosis of your problem and determine whether it is likely that a new laser assembly is needed. It is a good read that may save you both time and money.

I had the Micromega stage 2 and had this skipping problem. Later i found because of dried up grease that is causing the jerking movement of the lens on the transport metal rod. Cleaned and put teflon grease and it was fine.

Bought a spare 12.4 for S$15 dollars as a spare.
