FZ-1 not reading discs
Usual story with an FZ-1, but I just wanted to check if anyone more experienced had any other ideas as to what the problem might be before I write the laser off as dead and say it's ODE time.
Things I've checked:
- Wormgear cogs (not cracked, no broken teeth)
- Wormgear motor (spins when 3V is applied, spins laser rail)
- Spindle motor (again spins when 3V is applied)
- Cleaned laser lens with IPA
- Adequate lubrication on rails
- Laser stop switch is working, pressing it manually with multimeter probes attached shows continuity
- Majority of caps appear to have been replaced properly by previous owner with Nichicons (including disc drive board)
On boot, the laser starts moving backwards from the centre spindle in three movements, the laser moving up and down trying to focus all the way. It gets to around the middle portion of the rails and gives up, and the 'insert disc' screen appears. At no point does the spindle motor actually rotate.
When an audio CD is inserted, the behaviour is identical.
Replacement lasers are around the same price as an ODE from AliExpress, so if the laser really is dead, I'm not getting another.
