I am so happy found this site as it consists of so many Manuls and easy to aquire. This onei s exactly what I wanted and much more as it has info on not only how to use the tuner but how to repair it as well. I will come here 1st before purchasing else where! Thanks owner-manual.com!

Top class product, I printed it out on A3 paper and it is clear and very easy to follow.
Cheaper than buying a new radio!
;
is part of the manual is very useful for repairing
Here are circuit diagrams
if there is damage, I recommend using this part of the
a complete list of circuit boards and components
ELECTRICAL ADJUSTMENT-7/8
2. Servo Adjustment (RF PLL Adjustment)
* * This adjustment can be performed even when the TOP cabinet, operation board or TFT block is removed. To avoid counting track jumps as errors, track jumps are not performed in the test mode and recorded spiral pits are read, unlike during normal DVD playback. Therefore, during service mode startup, only the Aiwa logo appears; the pictures and sound recorded on the disc are not output. During test mode startup, the OPEN/CLOSE detection switch is disabled. During test mode startup, keys other than the POWER key are disabled. The test mode automatically ends after 6 minutes (The disc rotation stops.) To continue the test mode, turn on the power again.

<XD-DW5 MODEL>
No. 1 2 3 4 5 6 7 8 9 10 Contents Short pin-4 and pin-6 (ground) of CN400 (not mounted). (Preparation for test mode startup) Connect CH1 of the oscilloscope to TP400 (IC400 pin-5) and connect CH2 to TP315 (IC450 pin-60). Insert the test disc (MDVD-191). Turn on the power. (The test mode starts.) Confirm that the pickup reads the outermost circumference of the disc. Rotate VR300 right while checking the waveform of TP315 becomes 4.5±1.0V. Check that the waveform of TP315 is fixed HIGH and the voltage of TP400 is less than 400mV. Turn off the power and turn on again. Confirm that the pickup moves to the innermost circumference. Check that the waveform of TP315 is fixed HIGH and the voltage of TP400 is less than 400mV.
<XD-DW7 MODEL>
No. 1 2 3 4 5 6 Contents Short pin-4 and pin-6 (ground) of CN400 (not mounted). (Preparation for test mode startup) Connect CH1 of the oscilloscope to TP400 (IC400 pin-5) and connect CH2 to TP315 (IC450 pin-60). Insert the test disc (MDVD-191A). Turn on the power. (The test mode starts.) Confirm that the pickup reads the innermost circumference of the disc. Gently rotate VR300 left while checking the waveform of TP400.(The waveform moves rapidly) Then rorate VR300 right gently so that the voltage of TP400 is minimized (less than 400mV). 7 8 9 10 Rotate VR300 left so that the voltage of TP400 is 50mV more than minimum value. Turn off the power and turn on again. Confirm that the pickup moves to the outermost circumference. Check that the waveform of TP315 is fixed HIGH and the voltage of TP400 is less than 400mV.
