ecelent I was reciver the service manual soon I fell so happy very complete 100% positive all by this store tanks atte Luis salazar
 ;
A great copy of the manual, and the only one I could find anywhere on the net! The circuit diagrams are easily readable, all component values marked and easy to see. A highly appreciated download!

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.
Check IC1406, IC1407, IC1408 and their peripheral circuits.
