The panasonic CD player (SAAK133) is not working. The display says "No Disc" even when CD is inserted. It was not being used for some time.

If a no read situation either a dirty or more likely failed optical pickup in the unit.

Hello
Clean the laser pickup lens by insert a lens cleaning disc into the set, and play it at least three times. If it does not help you. replace the laser pickup unit, with same type and number. OK.

Hello
Insert a lens cleaning disc into it, and play it at least three times, after eject the inserted disc. You can buy this cleaning disc from most of the electronic spare part selling shops at your town. If the fault is due to accumulation of dust or dirt on the focussing lens, the cleaner disc will clean it, and your set will be alright.
If this does not help you, make sure that the laser pickup unit of your device is faulty. Replace it with same type and number. OK.

Hello
It seems that the Laser Pickup unit has some troouble with it. Just inser an audio CD and see whether the player reads the disc. If it reads, try with an MP3 disc. If these tow types of discs go with and not with DVD disc, make sure that the Laser Pickup Unit has the trouble. It has to be replaced with same type and number. Actually this is a very skilled work, as you have to disassemble and reassemble the DVD mechanism If you have confidence, and have all tools to do this work, you can do it by yoursef. Otherewise, get this set repaired, either by any experienced service technician, or by the Authorised Service Center for Panasonic at your town, I recomend you to get this set repaired by its authorised service center itself. OK.

u mabe inserting the wrong disc all phillips cd recorders uses cd-r or cd-rw that says digital audio.

i have the same exact jvc i see the same in the display,but i uses the maxwell or sony cd-r digital audio cds that what i will recomed with that in display it show up sometime not all the time then go awy uses digital audio as i said b 4.

If it doesn't turn the disc it can't read the data and 'know' from that there is a compatible disc inserted.

You may have gotten hosed by the seller. Until you get it to play with a commercial music CD I wouldn't try anything non-standard or home-grown. It doesn't play anything but CD-A music so MP3 and AVI discs would not be recognized anyway.

Before you dive in and possibly wreck it, read this...

Hi , Just simple ,
option 1:
Please open case and clean the lense
or
option 2:
use good lense cleaner cd with liquid.
just drop liquid on to cd cleaner ( excatly on brush)
then you run.
it will solve your problems.

OPEN DVD PLAYER AND USE A HAIR DRYER TO HEAT AROUND THE LASER AREA FOR ABOUT TWO MINUITES IF THIS DOESNT WORK REPLACE THE MOTOR

The player cannot read the data on the CD. The laser maybe dirty or defective. Before sending for repair try to use a disk cleaner.
