jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
Instrukcja bardzo czytelna. zawiera co potrzeba. Polecam

* : The electrical components differ according to the version of the system control IC (IC801). When replacing the IC801, check its model name and add or remove D1001 and/or R1001 as shown below. RU6815MF-0004 (Ver 3.0) .... Add D1001 and R1001 RU6815MF-0005 (Ver 3.2) and later .... Remove D1001 and R1001
