Home Cinema Set switches off when I put TV 40pfl8007 on standby
I have connected my 40 pfl8007 with my Harman Kardon Home Cinema Set via HDMI. Also, my HCS is connected with an Apple Aiport Express. When listening to music via Spotify I use the component input on my HCS. Last Friday I bought my TV (40pfl8007) and although I did not connect the remotes of HCS and the TV, the HCS turns off as soon as I put the TV on standby. Moreover: as long as my TV is on standby modus, I can turn on the HCS but it automatically turns off in a few seconds.
Only when my TV is turned off completely (so not on standby) I can use the component output and listen to music via the HCS. But as soon as I do this, ambilight suddenly turns on!
Anyone knows how to prevent both these problems?
