The CD player on my JVC ultra-micro-component-system, Model UX-7000R, has adopted a habit of making a loud vibration noise, apparently in time to the speed of the disc as it lessens as the disc proceeds. It makes listening to CD's impossible. The illumination of the system also flashes in time with this. Everything else, RDS radio, AMP and AUX connections are fine. Can anyone please advise if this is terminal or something relative to the laser that could be fixed. Thank you.
