My asus nova p20 sounds like its trying to eject discs all the time after being on for around 20+ minutes. when a disc it put in it dosnt read it then ejcts it. if restarted its fine up till around 20+ mins. then does it agian. there is plenty of ventilation around the unit and its only 9 months old.

P20-437 Paper-ejection encoder sensor status does not change within 10 milliseconds after the paper-ejection motor is activated.

This error occurs when the encoder disc either breaks or slips off the motor. The encoder disc is either a plastic or metal gear toothed disc.

Well, the optical pickup is not able to read the disk. First off, did you use ESD protection when you installed it? If not, it may already be damaged. For more information, or should you have further questions, please visit my website at audioserviceclinic.com. You may contact me directly through the website. Thank you.

disc cant read the disc and will not eject the disc. I tried unplugging it and putting on and pushing eject. no good. what do you think bose 321 system ...

Turn off the power.
Press and HOLD the eject button.
While holding the eject button, turn it on.
This works with most players, but may not work with all.

there mite be something jammed inside the disk drive take a look inside to see if theres anything inside if so just pull it out with something long and thin that dosnt conduct electricity.

Try to press the Eject Button for 20 seconds and i think that will do a force eject
the other way is the paper-clip! Straightend a large paper clip, then with some needle-nose pliers created a tiny L-shaped hooked (about 3/16 or 1/8 of an inch). Inserted the hook side of the clip into the disc slot along the edge. Carefully moved the clip around until I located the hole in the disc, then gently pulled the disc out. Piece of cake, took about 2 minutes!

If it is a hd tv, they make a dvi to Hdmi cable, if not that you will have to buy an external tv out card most tv tuner cards have tv out capabilties, Try dazzle

It's probably just dirty opticals. Try running a CD cleaning kit a couple of times.

Two possible scenarios: First the optical pick up assembly that read the disc has malfunctioned or the eject button is faulty. Either way it is just cheaper to replace the DVD player with a standalone dvd player connected to one the tv input(s). Too expensive to repair just the dvd player if it is tv/dvd combo. The cost for labor and parts is more expensive these days to repair tvs or dvd player. For around $30 you can just replace...much more cost effective.

I think there may be a problem with the system (defective parts) - I, too, am having this issue. I am going to contact the BBB - maybe if enough of us complain we will get a recall. To file a complaint:
