hello. i'ved had my panasonic portable dvd-lx8 for over 2 yrs now and have just encountered the h03 error code. first of all....i have no computer it/technical experience, but have read that apparently this error code refers to a spindle problem. i have tried the following method (copied and pasted below) with success, however....have had to repeat this step several times. the track seems to keep getting jammed somehow. i wish i could take a better look to see if there is some sort of dust or something jamming it (the cables keep the housings so close together.) well, good luck to you....... "For the people who already own the device, I saw a solution posted for the HO3 error on the internet by a user named Hossan, and it worked after I tried it myself. All you need is a small Phillips screwdriver. Remove all 12 screws from the back of the player. After removing the back cover, you will see the unit with the laser lamp mounted on rubber suspensions. Carefully lift the unit off the suspensions. Turn the unit around carefully so that the cables don't come off. Close to the servo motor, you will see a small black thumb wheel. Turn it, and the laser lamp should move along the rotating shaft. Turn the thumb wheel, so that laser lamp moves away from the center towards the edge. That should release it from the stuck position. All this takes maybe 15 minutes. Don't let some service guy talk you into shelling out a hundred or more dollars for repairs."
