hi I have a sharp vz 2000 the problem I have is that I changed all the belts in the unit, and now plays like it should, but it won't record anymore, do I have to put everything back like the two half's as I've only tried it through headphones and tried to record from the radio ive left it in two halfs as it needs a clean, and I took the record player out as thats now working 100% but now when pressing the record function the record level,s don't move, and nothing is recorded, but when playing a cassette the levels are fine,im just hoping that when it finally ass dose back together the record function will work on the cassette
