Very quality copy of original service manual, which contains the circuit diagrams, PCB and lists of components, well as recommendation for calibration procedures of device, also everything else, that need for repair, tuning and use this oscilloscope.
All presented copies have high-resolution, so you can view all in detail.
This manual will very useful for simple owners and for repairers.
I recommend these manual, because myself is owner of Philips PM3216 and I need sometimes servicing these oscilloscope (principally calibrating).
Also, these document is an example of excellent design of technical documentation.

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
Troubleshooting
Are the pins at CN6051 and CN6002 supplied with voltages?
E
Is the reset signal H? (R1088)
Is the 27-MHz CLK oscillating? (X1001)
