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.
Fringe in picture
Picture is interfered by stripe shaped bright spots
There appear streaks or light color on the screen
Check if the antenna is correctly oriented. Maybe there is electric wave reflected from hilltop or building. Possibly due to interference from automobile, train, high voltage transmission line, neon lamp etc. Maybe there is interference between antenna and power supply line. Please try to separate them in a longer distance. Maybe the shielded-layer of signal wire is not connected properly to the connector. Check if interfered by other equipment and if interfered possibly by the equipment like transmitting antenna, non professional radio station and cellular phone.
