You need to program your sky+ remote control for a Samsung TV. You do this as follows
Turn your TV and Sky+ box on and press tv on the remote.
Hold down select and the red key together until the red light on the remote blinks twice (this is after about 2 seconds)
Press tv again, key in your new TV's code (should probably be 0060). The light on the remote will blink twice.
Press standby on the sky+ remote. If your TV switches off, press select. The light on the remote should blink twice.
If your TV does not switch off, press tv, then press standby. Repeat the sequence of pressing tv then standby until the TV switches off, then press select. If the light blinks 3 times your remote has checked all the possible settings for the code previous entered (0060). Check that you have entered the code correctly, if you have then the Samsung must now have a different code.
Turn your tv back on and press the tv guide key on the remote. The TV Guide menu appears meaning the remote control settings are made properly.
