Question about Sony CMT-HP7 CD Shelf System

1 Answer

CD unit Dear Dan, thank you for your reply, we have managed to get the CD unit out. It appears that what we think is the 'reading head', (underneath the CD unit on a 'hinge' with a circuit board and a laser on it), has a large plastic pin on it which is sitting on a circluar disc/gear above it, (which itself has two pins), and thusly when the circular disc/gear is turning, the pin get caught on the pin on the 'reading head'. If we pull the 'reading head' away from the unit there is no grinding noise. It appears to be out of place as if the pin should be on the inside of the circular disc/gear instead of on the outside, (closer to us than the internal unit). I know this is long winded so sorry for that. Many thanks Kasey

Effectively, the loading me4chanism is out of timing. This unit needs to be rebuilt. Why it became out of time is not important or knowable really. This is not a repair I would attempt without the service manual as these units have a specific re-assembly sequence. That sequence insures that the gear timing is correct.
Good luck.

Error message appears cd won't play


I don't have much to go on here. Can you post the actual message that shows up? Usually on these units, either the mechanism gets out of time or it gets jammed. The actuall message will help to determine which.

Thanks,
Dan

My DVR RW is not unable to read any DVD or CD. It cant read CD even while booting via bootable disc. The imae icon appears in the Explorer, but it cant read the discs.


Hello,

the fault is from the lens (laser) of your drive, that's why its not reading discs. The lens is weak such that it cannot load discs.

How long have you been using this drive? I think its high time you got another one.

Good luck.

DVD player won't play DVD, says "load"


The unit can recognize that a disc has been loaded but can not read the contents. This can be as simple as a dirty lens or more drastic like failing optics. Try cleaning the lens using a cotton swab and alcohol. If that fails to correct the problem and a music CD will play OK, then the optics are failing. DVDs require more laser power to read than a music CD.

I have a portable dvd player model number mdp1030 the unit keeps saying no disk I have tried numerous disks same results.


then i think the lens is not able to read the disk.

and so i would suggest you to buy a disk cleaner CD and run it in your DVD player and then use your regular disks.

if this is not working then it is some internal fault in your DVD players lens.

Call your store manager directly for any information you need. Just ask for the store manager. If he or she cannot help then call 1-800-WALMART and ask that your concern be forwarded to the District Manager and you expect a call back. My store manager tells me they will stand for you with the warranty people.

Cannot open DVD disc


Brain,
Is your drive supports DVD? Try to put a CD disc and see its reading or not. If this problem occurs for both CD's and DVD's discs then you might have problem in your drive lense. and if it only reads CD then your drive might not be supported for DVD's.

try to clean your drive lense using CD head cleaner, it might solve your problem, other than you have to replace your drive.

Thanks

Those "cleaning" discs are rarely effective. Open up the unit cna carefully clean the lens using a cotton swab and alcohol. Update this if that failes to resolve the problem.
