Thank You for fast delivery for the sheme.
Everything allright.
Thanks & best regards Franz

again you did a very good job. It was fast too. Photocopy are really readable and clear

Probably it never existed a 1081 official service manual from Commodore, it's look more like a NAPCEC service manual & diagrams compilation of the 1084 series and his variants, like the nap6523, 8cm505, 1084S, 1084P and obviously the 1081. It's more complete than other scans and the quality of the scans also are far superior. It has two circuit diagrams variants of the 1081, mono and stereo versions. It doesn't include a diagram for the Philips CM8500 or CM8501, they look like the 1081 but they are slightly different.

Rapid, clear well done as all the scheme I downloaded from this site. Great job very functional and very useful
9-5. Adjustment of White Balance for Manual Adjustment (method 3)
Adjustment mode: Two modes of Medium(Vivid) and Warm (Cool data is automatically calibrated by the Medium data) - Equipment : 1) Color analyzer(CA100+, CA210) should be used in the calibrated ch by CS-1000(.(LCD : CH9, PDP : CH10) 2) Adjustment remocon - For manual adjustment, it is also possible by the following sequence. Operate the zero-calibration of the CA-100+ or CA-210, then stick sensor to the module when adjusting. (1) Select white pattern of heat-run by pressing �POWER ON� key on remote control for adjustment then operate heat run longer than 15 minutes. (recommend) (If not executed this step, the condition for W/B will be different) (2) Changing to the AV mode by remote control.(Push frontAV) (3) Input external pattern(85% white pattern). (4) Stick sensor to center of the screen and select each items (Red/Green/Blue Gain and Offset) using D/E(CH +/-) key on R/C.. (5) Adjust R/ G/B Gain using F/G(VOL +/-) key on R/C. (6) Adjust two modes of Medium(Vivid) and Warm as below figure. (Fix the one of R/G/B and change the others) 1) Default : Medium(Vivid) 2) Push the �VOL +� key twice : Warm
Caution: Each PCB assembly must be checked by check JIG set. (Because power PCB Assembly damages to PDP Module, especially be careful)
10. POWER PCB Assy Voltage Adjustment(Va, Vs voltage Adjustment)
10-1. Test Equipment: D.M.M 1EA 10-2. Connection Diagram for Measuring
Refer to Fig. 5
10-3. Adjustment Method
(1) Va Adjustment
1) After receiving 100% Full White Pattern, HEAT RUN. 2) Connect + terminal of D. M..M. to Va pin of P812, connect -terminal to GND pin of P812. 3) After turning VR901,voltage of D.M.M adjustment as same as Va voltage which on label of panel right/top (deviation; ±0.5V)
(2) Vs Adjustment
1) Connect + terminal of D. M..M. to Vs pin of P812, connect -terminal to GND pin of P812. 2) After turning VR951 401, voltage of D.M.M adjustment as same as Vs voltage which on label of panel right/top ( deviation ; ±0.5V)
[ Refer to the below case to know what value is fixed. [CASE] First adjust the coordinate much away from the target value(x, y). 1. x, y > target 1) Decrease the R, G. 2. x, y < target 1) First decrease the B gain, 2) Decrease the one of the others. - In case of decreasing the x, decreasing the R : fix G - In case of decreasing the y , decreasing the G : fix R 3. x > target , y < target 1) First decrease B, so make y a little more than the target. 2) Adjust x value by decreasing the R 4. x < target , y > target 1) First decrease B, so make x a little more than the target. 2) Adjust x value by decreasing the G (7) When adjustment is completed, Exit adjustment mode using EXIT key on R/C.
