I can no longer read DVD's on my DMR-EH85 - keep getting "no read". I cleaned the spindle but this did not solved the problem. I ran the device with the cover and DVD tray out of the unit and noticed that the led does turn on but when backed away from the disk. The read head does five seeks and the spindle does turn a bit but the unit gives up on trying to find the DVD and issues a "no read" message. I also noticed that the unit indicates that there is a DVD in the drive when there isn't (DVD indicator is on). I reset this by depressing the up and stop buttons but problem persists. Any suggestions? Thank you.
