Question about Washing Machines

1 Answer

SA-CH64M does not seem to be opening the door or transferring the CD. In an earlier answer it was said to clean the laser lens eye. Where is the eye?

I have the cover off but access to the components is limited. Unit says SEARCHING the Error.

The eye is a tiny focused lens like in a telescope that focuses a laser light on the disk to read it.

My cd is not being read on my panasonic cd stereo system sa-ch64m?


I afraid to say the symptom indicates your unit's laser is faulty
First of all I would suggest you to clean the laser lens to see if it solves your problem.
1) Purchase a CD/DVD laser lens cleaner disc and run it through the system 5-6 times.
If you want, you can buy a CD/DVD laser lens cleaner disc by following this link- http://www.amazon.com/Memorex-CD-DVD-Player-Laser-Lens-Cleaner/dp/B00008EM7U
2) If your unit is not under warranty then try this step otherwise it will void your unit's warranty.
If the cleaning disk does not work then remove the cover of the device, you may be able to locate the laser eye clean the laser with a soft clean cue tip or a cotton bud using isopropyl alcohol.Then check with a magnifying glass for any traces of dirt.
If cleaning doesn't helps then you will have to replace the laser diode and replacing the laser diode is very expensive because it requires the entire optical pickup to be replaced and realigned.Therefore I would suggest you to please first of all enquire about the labor,installation charges etc before going for the repair because in some cases the cost of replacing the laser inside the unit will typically exceed the cost of buying a replacement unit.

My cd is not being read on my panasonic cd stereo sa-ch64m


A typical symptom is you insert a disc in the player and after a while; the CD tray opens again with the message referring to no disc being in the system. This can be infuriating because you can see that there is a disc, however, the CD / DVD player cannot.
Every time the tray closes, the laser beam fires two long bursts of laser light, and the focusing platform moves up and down attempting to focus the beam. This is the time when it is looking for a disc. If the laser has failed, then it will not be able to detect a CD and therefore the error message appears.
I normally do two things when this happens. I normally clean the lens just in case there is dust on it obstructing the laser path. If cleaning the lens does not solve the problem then I make sure the laser is working. Second Problem can we with your CD. After some time the CD coating gets deteriorate due to atmosphere, this damages the coating of CD/DVD where data is stored..
I hope try Different CD in your player or clean the lens if the problem doesnt solve, use a CD cleaner to clean it...

The television can read the DVD dis, in fact, it says that no disc is present.


Hi,

These are the only methods you can do to try and remedy the problem yourself. Aside from these steps, the unit is in need of repair to have the laser lens assembly replaced.
You can try several methods of cleaning the laser lens to see if it helps clear up the problem. The first is to purchase a CD/DVD laser lens cleaner disc, and run it through the system several times.

If your player is not reading any discs at all though, then try purchasing a can of compressed air (available at Staples, or Wal-Mart). Open the CD drawer, or remove the cover of the player by removing the screws on the rear of the unit. Then spray the can approximately 10" from the lens to blow any dust off of it.

If it still doesn't work, you can opt to clean the lens eye itself, by using isopropyl alcohol, and a lint-free cloth to gently wipe the "eye". Then use a dry spot on the cloth to buff the eye clean. If the CD player is still not reading discs, then the lens or transport mechanism is faulty and would need to be replaced.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Sometimes I get no disc error when insert a cd in my sony cdp-ex100 cd player


Put in an ordinary audio CD and play to notice if the CD is detected. If yes the optical is working, if not there is no laser scanning and the possibility that the laser head can be defective.
Now certain cleaner disks will not be tracked to run for cleaning as it is not read. Hence it will reject. So it is ideal to clean manually the laser head eye using a cotton bud with gentle pressure on the lens eye.
If there is no result then watch if the CD spins or tries to spin. If so the board seems to work unless a test is taken on the main board but the possibility of a defective optical head can be the suspected fault.
If any of the above seems otherwise we must recheck with possibilities of a malfunction of the main processor board

MY CAR AUDIO WONT PLAY CD


Hi,

Most CD players that would not play a disc even with a known good disc inside signifies that the laser eye/lens is not reading the disc. This could probably be attributed to:
1. dirty, damaged, inverted, blank, un-finalized burned CDs
2. defective, weak, dirty/dusty burned-out laser eye/lens;
3. dirty, dried up lubrication of the slider shafting (where the laser eye's carriage moves) or some other components; and/or
4. dirty, dried up lubrication, defective spindle motor.

A few things you can try:
1. Use a CD cleaner (readily available from most computer shops);
2. use a can of compressed air and blow through the inside of the loaded disc area;
3. gently tap on the top cover where you estimate the reading/laser eye/lens would be;
4. gently press on the tray door (if it's got one) once the disc is loaded;
5. relube, clean as necessary but that would require pulling the unit out of the dash.

Should this not be corrective, perhaps your best bet would be to seek the services of a qualified professional such as those in a Service Center. Alternately, your friendly neighborhood electronic shop should do just fine.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kindest regards.

Thank you for using Fixya.
