No more vibrations. I thought the disc has to be at an optimal distance from the stylus but it seems it's a range of distance instead of an exact one. |

Someone told me there is a screw at the bottom that lifts the platter to a certain height. Am I missing that screw? Here is a pic of the bottom.

Tried a different disc and it catch fines, so must be a disc problem. But the loud vibrations still exists. |

That doesn't sound like a lot. If you watch 1 movie a day, that's less than 18 months. |

How to clean fingerprints/smudges on the disc then?
How many disc plays is a stylus good for?
I know a disc is good for 500 plays. Will a stylus last longer than that? |

Found a new problem. Keep losing picture and the player makes a clicking sound when it happens. Bad relay switch?

It's working fine now after playing a disc for a while. Looks like I have to play a disc once a week to keep it from dying completely. |

Power cycling solves the problem for a few minutes, then bad picture, no color appears again. Is this a capacitor problem or dirty stylus problem?

No sound on RF either. Does this mean I also have bad audio demodulator ics?
What about the audio button on the front panel? Is it bad that it doesn’t do anything when I press it? |

No sound from L & R jacks and the audio button doesn't do anything when I press it. Here is a sample capture of Pink panther strikes again which I assume is a mono disc. https://drive.google.com/f ... |
