To follow up, I had to have the laser assembly replaced and TAP repaired my UX-3pi at a very reasonable cost. When I picked up my UX-3pi, I did ask about repairing other models in house. They said only the "pi" models can be repaired at their facilities. So if you have an older UX model, or if you have an X-0 model, the transport needs to go to Japan. I didn’t specifically ask about the DV-50/60, but the guy I spoke to pulled up a list of all models that have to go overseas for repair and he did not mention those models. The only other model on the list he identified was the A-100 amplifier.
