SOURCE: Sony CFD-G500 cd player

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.

SOURCE: Does not detect CD in drive.

do you have it apart enough to view the CD transport mechanism ? if i so is the CD spinning up ?
over time the laser brightness diminishes and is not eluminating the cd proporly, there is a brightnes controll on the laser assembly, this can be ajuusted to a small degree to restore oporation, mark the original position of the control, the controll is located on a small pcboard where the plug enters the laseser asembely, turn the controll clockwise only about 5 to 10 percent, now atempt to read a good known cd, if it reads, leave it, if not turn the controll counter clock by 5 to 10 persent of the original poition, now try the cd again, if it works leave it, if not the laser may be defective and needs replacing, all this is asuming that the lense is cleen so prior to ajustment cleen the lense, also insure the lense is in place, some lenses have fallen off in my past experiances, and may be rateling around inside the unit, don`t lose it, you can very carefully glue it back in place using crazy glue, the assembely is quite easy to replace, you will see when you have it apart, if you can find a new one for a reasonable price this may be an option for you, one other thing, observer the carage, note if it seems to slide tho the center and then position itself a small portion away from the center this happens only when the unit is trying to read a CD , if so good, if not this may be due to a defective home switch used to position the laser over the appropriate track to read the directory of the CD, you can see the switch, and can be easily replaced, you will know how when you see it, that's what i know so now you know, good luck

SOURCE: My sony CFD-E100 won't recognize CDs

use a cotton swab to clean the optical lens-which is seen by opening the CD cover. if after cleaning the lens it still doesnt play a cd - exercise all manual switches(could be a dirty cd/radio switch), several times. after these steps, and the cd still refuses to spin...its hopless. the optic is bad.and not economical to repair. bet the cotton swab does the trick.

My Sony CFD-S33 CD player has started only playing 10 min of each CD


Clean the optical pickup lens, by inserting a lens cleaning disc into the player. If it do not help you, repalce the optical pickup unit. Sony sets will have special type optical picku units. You might have to contact the authorised service center for Sony at your town, to get an original one.

Just bought a used sony cfd-c1000. It will play most of my burned cd's but not one specific one: they are all on cd-r and I burned them all the same way with the same program, any ideas why it won't work?


My first two thoughts are: 1) It's a defective disc or 2) The disc wasn't finalized after it was burned. CD-R discs will not play on any machine other than the one that they were recorded on until they are finalized on that recorder. If it will play on the recorder and it has been finalized then just burn another copy of it. I have seen disc compatibility issues on one disc out of a stack of 100 before.

I have a sony CFD-S01 which will play commercial cd's but when a cd-r is inserted it either won't recognize the disk or it jumps constantly after appros 10 sec, any ideas?


The CFD-S01 is designed for use with CD-R and CD-RW discs. With that in mind a few things come to mind. Are the CD-R discs you are using music or data discs? There is a difference and some CD players do not get along with data discs and won't play them well if at all. Also the burn rate used can have an effect - too fast and it won't play well. If a disc doesn't play at all it might not be finalized. A disc must be finalized on the recorder it was burned on before it is playable on any other machine.

My Sony CFD SO1 keeps skipping/display light keeps flashing


That is an electronic problem. Probably a just-about-to-break cable in the motor of the CD drive, that sometimes causes a short and turns off the unit, or sometimes makes it to comport erratically and produce the buzzy sound. If you have electronics knowledge, then you may open and check the wiring harnesses. If don't, take it to your local electronics repair.

Sony cd radio cassetteplayer says no disc when disc is in player


Make sure your cd medium is compatible with your Sony unit. Some cd types that have been burned on a computer may not be compatible. Check your instruction book for your Sony unit to see what types of cd medium you can use.. Also, the lens on you cd player could be dirty and may need a cleaning CLICK HERE to see the Radio Shack lens cleaner. You can also get them at may other locations like Walmart, Target, Sears, and Best Buy. Good Luck! : )

My CFD-Z501 won't play a disc. I get the message "no disc"


Try to use CD/DVD clening disk ($6 in Walmart). Or simply use cotton swab (Q-TIP) and 40 % ethyl alcohol (vodka) or 50-70% isopropyl alcohol (NO ACETONE), depending on your budget.
Also check if discs are inserted correctly and not damaged/durty etc. Also check your discs. Some CD-players dont accept burned CDs (copyed). I believe Sony is not the case, just a suggestion.
If cleaning wont help lens might be damaged.
Good Luck
