LaserDisc optical alignment?
As noted elsewhere, optics don’t generally drift except from abuse. The following is a further confirmation that optical alignment should not be needed under normal conditions: (From: Dave A. Wreski (dawreski@nic.com).) I have been servicing these since they came out. The *only* time I had to do any optical alignments is when some fool decided to mess with the alignments. They do not misalign themselves. In the past the only adjustment we had to do (on Pioneer Laserdisc players) is the 1/4 wave plate which can be done with a scope. All other alignments must be done with a Laser power meter and a polarization adjustment jig from Pioneer. Many dollars! If the optics are clean and haven’t been maladjusted, your unit is supposed to work. If not, look elsewhere in the electrical alignments or motor problems. (From: Sam.) I acquired a VP-1000 that indeed did have obviously misaligned optics. (This is a second VP-1000, not the working one described above.
