I will definitely be back for more information when I need it.

The service manual when downloaded and printed out was clear and easy to read. I would have liked to have been able to enlarge some details, but this was not possible as the file permissions did not allow this. The service was very good. The time taken from placing my order to downloading the document was only a few minutes.

The manual is useful for trouble shooting for an old instrument. It saved money,and let me enjoy DIY.
;
Perfect source of information for replacing the HDD and performing general diagnostics.

TROUBLE SHOOTING TABLE (Continued)
Checking the output PWB unit
Are there signal inputs at No SC1404, SC1405, SC1501 and SC1502? Are voltages applied to EA connectors and SC5502? If there is no signal at EA connector or SC5502, go to Yes Checking the power unitblock.
No
If there is no signal at SC1501 and SC1502, go to the video system block.
If there is no signal at SC1404 and SC1405, go to "Trouble shooting table for PC I/F unit".
Are there signal outputs at pins (14) ,(16) and (18) of IC1401 ?
No
Yes
Check IC1401 and their peripheral circuits.
Are there signal inputs at pin (47) of IC1101, IC1201 and IC1301?
No
Yes
Check IC1401 and their peripheral circuits.
Are there signal outputs at pins (17), (19), (21), (27), (29) and (31) of IC1101, IC1201 and IC1301?
No
Yes
Check IC1101,IC1201,IC1301 and their peripheral circuits.
No
If there is no signal input at pins (1) and (24) of SC1101, SC1102 and SC1103, check the switching circuit and amplifier circuit of IC1101, IC1201, and IC1301, and their peripheral circuits.
Are there signal inputs at SC1101, SC1201 and SC1301? Yes Yes
No
Check the R, G and B panels.
If there is no signal input at pins (8) and (23) of SC1101, SC1102 and SC1103, check IC1409 and their peripheral circuits.
