HELP WITH JVC THA5 Home Theatre

[klymax]

Please I need help with my JVC home theatre system model TH A5 model. It started with changing its source automatically on its own while watching a movie from DVD mode to FM/Alternative modes.
Next was I tried to remove a disc in it by opening the cover and pushing the tray forward. The DVD still came on but it refuses to signal 'Open/Close/No Disc' etc.
Now it doesn't even function at all when I change the source to DVD mode. But it works perfectly on FM mode and Alternative mode.[/b]

check u9 on mpeg pcb its a 3.3 volt surface mount regulator.
they go faulty and cause "wait loading" issue.
