My car battery died.when i put in a new my cd player stop working

Get a CD Optic Cleaning disc. It has small brushes that clean the optics. The tracking laser is lower power and a little bit of dust will make it so that it can't read the tracks.

try another cd wont play if too scratched or dirty. handle disc by edge, dont touch the surface of disc no matter how lightly you hold it, you will leave contaminants that cloud the surface. if none ever work try them in a house cd player still no joy, then discs aare no good, if they work in home player then car cd died, time for new one. heck who uses cd any more? its a hassle to change them (only 16 songs!), hassle to replace lost daamaged or stolen(borrowed by friends), skip or scratches, get a radio with usb reader/player or SD card reader, can be had for under $60 , an 8gb SD card for $25 (4,000 songs<do you even KNOW the names of that many songs?) PLus, without a cd slot the thieves should leave your radio alone, thinking its just a normal am/fm radio. goto www.dealextreme.com for great deals and FREE SHIPPING.

You need a learning remote control or check e-bay. Almost any Sony DVD remote will work. 10-20$ If you list the model # of the remote I may even have one. Hope this helps

face plate is going bad lcd is fading solution--replace face

by a new player i recomend sony,there still the best. dont waste your money on blue ray,they will be obsolete in five years and they are very slow,ie. loading and reading discs, i know i sell them

Very tricky, my suggestion is to restart the radio again see if it reads the CDs this time. Try removing the radio fuse, where all the other fuses are at. Turn the radio on without the fuse, press and hold a button for a minute just to make sure you drain the electricity from the changer. Then put the fuse back and see what happens. You can also disconnect the negative or ground from the battery wait five minutes and connect it again but this will also restart the car computer.

i fixed this exactly as previous posted solutions, however a couple of points.
a) recordable CDs work if you don't have a DVD burner.
b) I didn't have a CD burner that would do an "image burn", I downloaded a free copy of "Express Burn" and that worked fine. The disk needs to be "finalised" or "fixated", it should do this automatically, or it may be a tick box selection.
c) I got a "No DWLD 09" when I put the disk into the player. I found this was an incompatibility with the CD-R (Maxwell) I was using. I changed to JVC and it worked fine.

chek your fuses.

idk

try to clean the lens use coton and water. do not use cleaning disc.
