Electronics Repair Questions? Ask an Electronics Technician
Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Error 04 indicates that the CD cannot be read by the system.
Is this happening with just one CD or several?
If it is just one, then that CD may be bad.
If it is happening with several CDs then there is a problem with the laser head assembly.
It may just need cleaning - try running a cleaning disc and see if that helps.
If not, then the laser head assembly has likely failed.These will fail over time as they get weak. It is something unfortunately that needs to be replaced with precision.If you have some electronics experience and can solder well you can replace this part yourself. If not, it would really be best to have this serviced by local Audio/Video repair shop.
