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
;
Great copy of the manual, has all information required for servicing,

I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .

really a very good manual even sometimes the quality is no so good as before still very readible and very very useful!
(5) Lighting in green, and then in red (Alarm of power voltage error) Unlike [lighting in red] in the STANDBY mode, [lighting in green] continues for about 30 seconds without any output of images and audio signals. Since then, the mode turns into [lighting in red]. (Caution) How to reset the alarming condition The alarming condition can be reset when an OFF�ON setting is repeated twice for the main power supply in the state that the LED is lit in red. The interval between the first and second settings is not particularly specified.
Lighting in red
Make an OFF � ON setting twice for the main power supply in order to reset the alarming condition. Is the LED lit in red after it has been lit in green for about 30 seconds? YES When the main power supply is turned on in the state that the AD, PD, and PH connectors are disconnected, are there the Vs (170Vdc) and Vd (60Vdc) outputs at Pins 6-7to Pins 9-0 of the PD connector and a 5Vdc output at Pins 1-2 of the PH connector? In this case, is the LED not turned in red after it has been lit in green for about 30 seconds? At that time, however, no images are generated. NO When the main power supply is turned on in the state that the PA and PV connectors are disconnected from one after another, is there a 12Vdc output at Pins 1-3 of the PA connector or the 12Vdc and 6Vdc outputs at Pins 1 and 3-4 of the PV connector? In this case, is the LED not turned in red after it has been lit in green for about 30 seconds? NO Is there an output of 3.3Vdc available at Pins 1~3 and 2.5Vdc at Pins 7~9 in the state that the PA and PV connectors are returned to the former state, the main power is turned ON, and the PN connector is disconnected? In this case, however, this check must be finished in 30 seconds. Otherwise, there will be power tripping on account of an alarm. NO
Normal
Refer to P7-1 "HOW TO DIAGNOSE THE PDP MODULE". YES The PDP is fault. (Caution) The voltage values of Vd and Vs can differ according to the PDP. The method of checking these voltage values is obtainable from [2. Adjustment of the power unit] in the method of adjustment.
YES
The MAIN PWB or the AUDIO PWB is fault.
NO
The Power unit or the PN connector is fault.
YES The MAIN PWB is fault.
