Question about Onkyo MD-133 Personal MiniDisc Player
Deck was playing a HI MD disc then stopped suddenely with message of read error.
I changed discs to another HI MD and normal MD which just kept showing message of reading. Deck would not stop reading and also would not eject until i turned power off and on.

sounds like the optical pickup is going bad. replace the optical pickup part # 24801016A you can get it at www.vancebaldwin.com . there are four electronis sensors inside the pickup A,B.C,and D. this is the focus and read sensors. the laser must land on all four of the "pads" (sensors) these can appaer to work at first but soon begin to degrade their read ability. the E, F sensors can also cause this problem. no the sensors can not be replaced it's the whole assebly.

The unit can not read the discs. It will search through all 6 positions then quit. Try opening up the unit and cleaning the lens using a cotton swab and alcohol. Update this with your results.

Dust infiltration is a likely culprit. Unplug the unit, open the case. Take a cotton swab and wet it with a small amount of glass cleaner. Gently wipe the laser lens several times without applying pressure, then use the other end to finish cleaning it off and to dry it. Often, so much dust gets inside these units and coats the objective lens it can't see the disc anymore. Give it a try, might work after this operation. I've fixed many CD & DVD players this way. If that doesn't work, take a can of compressed air and blow out dust from inside the laser by pointing the nozzle to the open space between the lens and the lens cover. Hold the can at least three inches away so as not to damage the internal workings of the laser assembly. Several short/sharp bursts of air might dislodge dust that has accumulated inside the laser housing.

Well I have been repairing dvd players a while now and the main problem spots are laser ,spindle motor, laser tracking motor and the biggest culprit and un suspecting one the lens cable .....most of them range from the lens cable to the spindle motor though... the constant movement of the lens in watching a whole movie causes the cable to unknowingly and slowly break and if the spindle motor is defective ,on inserting a dvd the disc spins slowly and you may hear the lens chirping ... so you can check those....
