Well, this transport with version 21LD optical servo board is only available from China. The 1202 at MCM is appears not the same unit as in my player. Prior to reading here about "don't adjust". I took apart the machine and asked the importer to order me a whole new complete transport. Upon close inspection, I noticed a small screw to turn right under at the disasembled laser head. Tried 1/8 clockwise, put the thing back together and no dice. Then 1/8 counter clock and bingo. Now, I recently aquired this player second hand in mint condition and its been nothing but transport troubles. Now I know why the original owner was so eager to dump it cheap. I'll put the new assembly away in the draw, but am thrilled to learn that a VAM1202 can be adjusted . I hope it stays working as its a PIA to break this unit down for service. I hope others can gain some insight from my experience.
