Hello. After buying a philips android tv with ambilight model 7303/12, I can't pair the remote control with it. Remote control test with digital camera negative, no infrared flash visible. When the batteries are inserted into the remote control, the blue LED on the remote control flashes for a moment. Unfortunately, only at this moment. The remote seemed to have no power at all. This blue LED should light up for a few seconds after successful pairing and only blinks for a fraction of a second when the battery is in power. Unfortunately, without the remote control, the TV is useless for now. It does not even work in infrared, not to mention voice command options. There are some strange contacts in the battery compartment marked in the photo. What are they for. Could this be the cause of the error? I am asking for advice. Without a TV like without a hand ?
