Schematy są ale można wysilić się i zrobić kolorowy skan i o większej rozdzielczości. Wtedy schematy płytek będą czytelniejsze. Całość super jako wartość merytoryczna. Wszystkie dane potrzebne do podłączenia różnego rodzajów urządzeń takich gramofon, CD itd.
;
Szybko, sprawnie i tanio. Serwis godny polecenia. Będę polecał innym
;
Ogólnie jest OK, z wyjątkiem obrazu płyty głównej, który jest miejscami mało czytelny, ale można sobie poradzić.
;
Dokładna dokumentacja, pomogła w szybkiej naprawie telewizora. Dziękuję!
;
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.
