Given that the machine will read disks it has written itself but not play regular discs, I suspect the lens assembly is slightly out of alignment and needs adjusting. This is not normally something you can do at home unless you have the correct test gear. It will need to go to a repair shop.
One thing you can try before that is to clean the lens. Buy a quality (Scotch 3M, Philips ) cleaning disc and try it. Could be it's only a speck of dust on the lens.....
This is not a problem but may be due to the surge current that occurs due to the charging of the power supply Filter capacitors. This might be made less with some silicone sealant. Best to have a Technician look at it as it could also mean a too high of current draw due to aged and defective Chinese Capacitors- yes the have infiltrated this business too and are the result of many a failures including flat panel display TV's and computer monitors.
I have the c521i with similar problem. It will play discs most of the time and sometimes can go for an hour or more before hanging up. Sometimes the disc is spinning and the laser is moving up and down (clicking) trying to read data. Sometimes the disc will stop spinning.
The replacement laser mechanism is a Sony KSS-213C and can be found by a few resellers on ebay for between $10 - 26, and also online at stores like MCM Electronics. This assembly has the laser head, gears, everything that needs to be replaced. I should get mine in the next few days. I also bought the 16 pin flex ribbon cable that is about 8 inches long that connects from the laser and goes into the circuit board. With basic DIY skills, this is a simple fix. A little care and effort is required on the laser assembly. I am told this will fix and will report back as soon as I get it installed and can verify it works.
hi, i've had a few nad C541i's and not so long since the sound on one of them cut out for milliseconds and on some occasions the sound would make the noise very much like a severely scratched vinyl record, i thought it was a faulty laser so i tried another KSS-213C laser out of a scrap kenwood and the fault persisted. to cut a long story short, i took the main PCB out and there were various dry joints. once these were resoldered i was blessed with a fully functioning player. hope this helps?
1. Most of the player drawer fixed over the chasis for a rigid support 2. try to remove the drawer safely without damagind the chasis and drive mechanism 3. there might be some shaft jam. 4. Look for the thread. how does the player drawer moves in and out 5. there may be some sensors to sense the door close/open. if it is jammed then open/close function cannot be done. why because this problem occurs 6. unwear the mechanism read the mechanism moving technique. see which has got jammed. 7. if you feel too risky then 8.contact service centre... all the best
found same problem with mine, solution .. place clean paper over the optic, then a magnet, leave for a few seconds, the build up of static causes a magnetic field in the optic preventing it tracking, have cured a few other brands with this as well .. shows manufactures are putting inferior parts in to their players, hope this helps !!
