Excellent service manual, the only known point of note is the alignment of improvability scanned pages within the pdf page. The resolution is good.

Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!

It was just what I need to fix my old BMW's CD player. Very convenient also. Thank you.

Great Manual! It contains all the wiring schematics and mechanical exploded views that are essential for service and repair. I was surprised I even found this for such an old machine. Only wish I knew of this site many years ago.

5. DIAGNOSIS
A
5.1 POWER ON SEQUENCE
Power On Sequence
Pressing of the POWER key is detected by the IC3601 Submicrocomputer on the MAIN Assy. The IC3601 then outputs a POWER_ON signal to the SYPS Assy.
After receiving the POWER_ON signal, the SYPS Assy activates, secondary Power, setting it to ON.
B
The SMP8634 (IC1001), the core LSI, starts up.
Communication between the SMP8634 and the DDR SDRAM starts.
C
Communication between the SMP8634 and the FLASH_IC starts.
It takes about 1 minute to complete the startup process.
D

Are the pins at CN6051 and CN6002 supplied with voltages?
E
Is the reset signal H? (R1088)
