Majestic DVX-478 USB repair brief
Received with 90% failures on startup sequence. Some swish comes out from inside during startup.
Investigation revealed the swish as originating from the lens touching the dvd support as soon as the autofocus procedure starts.
Tweaking the F (focus) trimmer less that 1/16 of degree clockwise cured the problem. The trimmer is located on the laser pickup.
PS: how to turn a trimmer 1/16 of a degree is left as an exercise to the student..... :=))
