Guten Abend!

Ich habe eine Bitte: Ich habe seit einigen Tagen einen Diskman Sony D-20 (angebl. baugleich mit US-Version D-2). Das gute Stück bräuchte einen Service; er sollte als Diskman nicht so leicht "aus dem Tritt" gebracht werden können, aber das ist hier doch der Fall. Die Serviceunterlagen liegen vor, habe ich inzwischen hier hochgeladen, schicke ich aber gern auch als PDF per Mail, falls hier nichts dagegen spricht (stammen ja aus meinem Besitz)?

Aus sicherlich verständlichen Gründen möchte ich das schöne Stück keiner "normalen" Werkstatt anvertrauen, sondern würde mich freuen, wenn mir ein Mitglied den Service machen könnte, der Freude an der Technik hat, wie wir alle hier. Das ganze natürlich gegen Erstattung aller Kosten, inkl. Hin-, und Rückversand.

Ich würde mich über entsprechende Angebote sehr freuen!

Mit freundlichem Gruß.
