As Always you can find here manuals even of difficult TV scheme which are scan in almost perfect way.clear and fast!!!!!
Great work thanks!
;
Incredibly clear!!!! Well done, complete and wonderful. It could not better than this!!!!
 ;
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.

* Measure the resistance from X602 pad 5 to ground (>100 kohms). * If it�s too low, make sure there�s no dirt or oxide between the components in the marked area (�g. 4.5). Clean thoroughly and measure again.
Fig. 4.5 * If the resistance still is too low, remove R601 (class A, �g. 4.4). * If the resistance increased, replace D600 (class B, �g. 4.2) and mount a new R601. * If the resistance didn�t increase when removing R601 or it didn�t help by replacing D600, send the phone to the next level.
* Measure the resistance from X602 pad 3 to ground (>100 kohms). * If it�s too low, make sure there�s no dirt or oxide between the components in the marked area (�g. 4.5). Clean thoroughly and measure again. * If the resistance still is too low, remove R605 (class A, �g. 4.4) and measure again. * If the resistance increased, replace D600 (class B, �g. 4.2) and mount a new R605. * If the resistance didn�t increase when removing R605 or it didn�t help by replacing D600, send the phone to the next level.
If all the above measured resistances are correct, but some of the voltages at R601 or R605 are low it�s either caused by a slight short circuit due to dirt at the marked area in fig. 4.5, broken F603 or broken F604.
� If the voltages at R601 and R605 are correct, connect a handsfree to the system connector. � Measure the voltages at both sides of R601 (~0V, �g. 4.4) and at D600 pin 70 (~0V, �g. 4.2).
