Re: won't read disk
I had this problem on my Panasonic since it has a mechanised front tray loader. There are a couple of things you can do: clean the CD with toothpaste and dry the CD with a fabric cloth - not paper as this will scratch the CD.
Vacuum out the CD player by using a crevice tool and carefully insert into the mouth of the CD player to get rid of any dust.
If the CD has been burnt from a computer, it may not recognise on the Sony unit even if it states it can play CD's from PC/Mac. Usually after a CD has been burnt its best to play it on your computer before transferring to the stereo unit of your choice.
Usually the clicking noise means that the music is trying to get through but something is stopping it.

In most cases when the CD does not play it is possible that the optical head is a suspect. Sometimes it might pick up ordinary audio CD but will not play other formats. This indicates that the optical head is weak and so there is no detection or scanning of the CD . If the optical is working the tracks will be read immediately but with no scanning the laser head can be defective. Sometimes certain cleaner disks will not be tracked to run for cleaning as it will not be read and so will reject. Hence it is ideal to manually clean the laser head eye using a cleaning swap /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
First take a disk player cleaner and run it through two complete times. It is quite possible that the lens on your your CD players has become dirty and just needs a good leaning. this is quite normal actually. Any lens that plays a disk should have a good cleaning weekly to give optimum performance. Overtime dust collects and prevents the lens from reading the disk. The lens disk cleaners have tiny gentle bristles that "sweep" the lens back to normal.
Also you want to make sure that there are no smudges or scratches on the disks themselves. Often time a gentle wiping will remove smudges but if the disk has some scratches it may need to be resurfaced. A resurfacing cost about $2usd at your local record shop or gamers/video store.
Now if neither of these solutions work , and often they do, then it is possible the lens has come out of alignment and this would have to be addressed by a tech. A lens only need to move a mm for it to not be able to read a disk properly.
If you can disassemble the CAP(disc holder) and place it on the disc while it is on the spindle and at the same time push the (hidden)lid switch you will see the lazer"s lens move up and down while trying to focus on the disc. If the lazer see's the disk it will tell the motor to turn. If it dosn't see the disc it will not turn the motor. Some model will kick the disc to spin a little while trying to see the disc. This type of player can be tricked into seeing the disc if you spin the disc a little by hand when the lazer's lens is moving up and down. At that point in time it might see the disc and take over the motor and spin up to normal speed. If the disc is an illeagal copy sold as a original the quality of the disc could be the cause. If the player is very clean (no small hairs stuck to the glue that holds the lens in place) (never clean with a cotton swab, use a shammie swab with rubbing alcohol or isopropal 99%) the problem could also be that the lazer is just not strong enough and the whole lazer-motor assemble should be replaced. Older units could use 1 drop of light motor oil on the motor shaft at the bearing to help start the motor when the system kicks the disc to spin. If the player reads the disc at the time you manually spin the disc maybe a good cleaning and oiling is all that is needed. The disc spins clockwise. if the disk spins counter clockwise replace the whole assemble. Maybe simpler, just give the disc a good clockwise spin and quickly close the door and push play while the disc is still spinning. if it starts, there you go. Don't use caned air on the lazer assemble. it will blow the dirt further into the lazer mechanism under the lens and make matters worse! Good luck!!
buy a cleaning disk, or get a micro fiber cloth, and take the stereo apart and find the laser lens, near the motor that spins the cd, it will be pretty small, gently wipe it clean in one direction, if that doesnt work, the laser has quit working.
when you get an err message it means that the eye of the cd cannot read the disk. when was the last time you put in a cd cleaner? one that you put into any cd player. you can get one at your local big lots or radio shack or best buy. you need not spend a lot of money for one. or you can try to use a cuetip dipped in alcohol and clean the eye only. dry with another cuetip or soft cloth and see if that solves the problem.
?: Does the cd spins? If it does the optical eye that reads the cd could be dirty. Clean the eye with cd lens cleaner. If the cd is not spinning the motor could be bad. Also some cd players can't read certain disks because of the density of the disk. Make sure you read the manual to see what cds are compatible with your boombox. I hope these solutions were helpful.
There is an inherent problem with this unit that is not the reader.I noticed that the red light which comes on when the super base is activated will sometimes flash while the unit is first trying to read the CD.It seems to be in sync with the disc spinning motor of the CD player.I have repaired a couple of these by checking and resoldering poor quality solder joints on the CD sub board and a few on the main circuit board.But this has not repaired all of them.Sony need to look into this.
