After just over 2 years, the first remote control has suspended. I never imagined then here at Amazon a new original remote control of Sony bought. This has again working properly. The old, I then, as here partially Proposed opened and gereiningt of the aforementioned liquid inside. Unfortunately without success. Less than 2 years later showed the remote control again refilled, the same deficits. A second attempt at repair the First, by adhering aluminum foil under the non-functioning buttons, helped about 2 months. Willy-nilly I have to buy a third Fernbedinung now so. That must not really be, Sony!
