try cleaning the heads , unpluge it , take the top off , , put a tape in , you will see the heads comming to meet the tape, so you know were the heads are , take the tape back out . use cotton ear buds, to wipe the heads , dip them into white spirits, to wipe the heads , but dry heads off with a new ear bud , see how you get on , ( be carefull )with the power,,,,,
