Onkyo cd player skipping
Supply voltage between Vcc and Vee is 28-29V, near the maximum ratings (from Sanyo datasheet).
#Onkyo cd player skipping driver
spindle motor driver (LA6500) has no heat-sink and get warm (at idle too). I have no schematic, anyone has it? for free? thanks! results: nothing re-trimmed laser current to original value. tried: slightly trimmed the laser current for obtain a slightly more power added: 100nF capacitor on the spindle motor. added: 1nF capacitor (between positive and negative) on the spindle motor. changed with a new one: spindle motor driver, LA6500 (op-amp 1A, 30V) labelled Q108.
verified: spindle motor (run normally in clockwise and anticlockwise direction, absorbing something like 0.7A max 5V, with cd inserted) This time, unluckly, I have no solution to the problem, so I'll try to explain what I have done: It seems to be a common fault on old Onkyo cd player, as you can find in other threads in diyAudio forum. Sometimes cd starts to move for only a few degrees of rotation, then stop immediately and cd player goes into "locked" or "no cd" state. When it loads a cd, the lens of the laser laser pickup (KSS 152A) goes up and down a couple of time, then the laser turn off and cd player seems to go into "locked" or "no cd" state.ĭuring this time, cd doesn't run (spindle motor is off). One of my friends gave me (for free.) an Onkyo DX-1500, a 18 years old cd player.
