The old Fernbedinung needed now 4-5 keystrokes to a reaction of the TV trigger-off sometimes completely unmöglich.Auch new batteries brought nichts.Hier I found the original part to reasonable price.The serial number is completely identical, the key layout and appearance are the same .If the Keys however, there is little Unterschiede.Egal it can get used-each keystroke is immediately converted back to the TV. At Philips online services, incidentally, not a replacement could be found!
