The "Vol+/Vol-" of 551R remote control (even with Amp disconnect from AC) change channel on my Tv (42PDL7906H/12, led blinks on TV), I have another Philips TV (26PFL5322/10), the led blinks but no reaction from this TV.
I have also a problem with ARC, when I power on the "551R" this play TV sound, but the speakers of the TV play audio too.
