Problem connecting Bravia with Android phone

[abunea]

 Hi,

I have a problem connecting my TV - Sony Bravia  kdl-32hx751 - with a HTC Desire 600, with Media Remote app.

1. Have tried connecting both devices to the home wi-fi network, then searching for the TV in the Media Remote app, but it cannot find it.
2. Tried connecting via Wi-fi Direct, after connecting to the Wi-fiDirect network (pairing via PIN), it gets stuck at authenticating and keeps disconnecting and trying again.

Steps taken so far: restarting both devices, deleting the network and restoring, repairing the devices, clearing the accepted devices list (the phone appears as an accepted device in the list, but it doesn't connect)

Nothing seems to work, although I have tried the steps from the i-Manual and also review the troubleshooting info. LAN settings are On, Wi-fi Direct is On. 

What else can I do?
