D-T10 not tracking

Jehr

Hi Kaosun,

I have a D-T10 that I picked up.  I freed up the intermediate gear, cleaned it up and it worked great.  I took it apart again to probe the charging circuit and managed to blow the fuse (which I replaced).  The unit will now not track a disc, you can hear the head chirping trying to find the track but it gives up.  I put it in service mode:
1) There is laser light
2) UPF current value is in spec
3) The sled goes back and forth smoothly
4) Motor spins up fine
5) Focus search works
6) When I press KEY-MODE, I am not sure that tracking servo is working properly?
7) +B / -B Voltages are in range

I am just about to give up and send it to you, but I thought I would see if you have any ideas first.  It looks like I messed something up maybe.  

Thank you and happy new year.
