Hi I´ve buyed a used mt866. Now the problem is - if I layed horizontal the md it runs alltime ok, but if I moved in the verticaly or between it runs but the sound stops and the counter stands on the last time he played. I think its a problem with the mechanic between the disc and the player. I´ve cleanded the lens and the frictionwheel with a q-tip and a drop of alcohol, but it doesn´t work. Have anybody an idea???
