I have 100 Cd Drive

[watzmann]

Halloo,

i'm going here to ask a very interesting question and i hope to find an answer.
i have about 100 cd rom drive but it's not working , i hope to able to repair them but i don't know too much about Cd Roms problem except it's lenses faults,
in all the cd roms drives i have i'm sure that is not a problem in the lenses.

so i need to know if anyone here have an experiance with cd rom drives , for example if any one knows the most common problem which cd drives alwayes have, that really will help me too much.
espacially that i have an experiance in repairing hard drives boards and i successed in that many times.

so please if anyone knows a link or a topic which may help me to undersatnd alittle bit about the function of the cd roms mainboard components just write to me some.

or

if you have repaired a cd rom before and you can tell me somthing useful that's will be great ,
at the end i want to say , i'm really know that many of our spare devices may have a transistor or a capacitor which is not working probably and if you replace it then your hard disk or your cd rom drive can work again !!!, that's very interesting

thanks for advance

With CDROM drives usually going for $30 or less, how much time and what amount of spare parts can you invest? At the going rate of a skilled enough repair worker?

Answer: Zip. Nada. Null. Nix. Niente. Rien. Semmi.

Them being this cheap is also the main reason why so many CDROM drives fail so soon. I have customers who are on their 3rd or 4th CDROM drive - even though they hardly ever use them.

Unless you have a pile of all identical ones that have a common "weak point" kind of failure. Figure it out on one, and fix them all. Chances are that they'll break again soon after anyhow.

I think he is talking about the 100magazine Audio CDRom variety. From my experience, it's the plastic slides, etc that wear out from use. My PSX had a problem reading discs, or it would just quit at some point in the game. I pulled it apart and found that the rails the "eye" slide on had been worn enough to tip the eye enough for it to get off track and read the wrong data, thus locking up the game.

I find that whenever possible, I like to pull the cover off the offending device and watch how it is actually working...see if it is hanging on something, if something that should be moving isn't...etc, etc, etc.

Hope this at least hleps you identify the problem with the player.

you know ,. i tried with 4 drives so i opened them and tried to check them out ,

you know 3 of them worked very good , s i was so surprised for this result but i liked it too much ,
the main problem was alwayes with the flat cable between the lense and the main board , when i chaeck it i found it not working , and i don't think that's a temp fixing,
they working so nice without no problems, that's nice ,

the thing i need is , if anone have an experiance with fixing his own drive before just tell us about it , it may be so helpfull, and as for me i'll tell you alwayes what i found in my drives,

so if anyone know anything plz tell us ,
by the way , Mr.Peter M, it was so nice to hear from someone from Augsburg, i was there last year , it's a so nice town,you know i'm from cairo in Egypt.

thanks too much
