Hello Friends , Am having Sony Bravia Tv ( KLV-40R56C ) with Airtel HD STB Connection , Yesterday i Connected my Tv with the Laptop using HDMI Cable & everything was Fine . After that i disconnected the HDMI cable from my Laptop & connected back on the Airtel HD STB , now the problem started . when i switched on both TV & STB , first it was black asking to check external input within few secs once my STB Is on the screen shows Loading Airtel DTH & after 1-2mins it displays Error b001 with audio , My STB LED glows in somewhat orange colour . i removed cables & checked all connections , everything seems fine, guess issue is with my Airtel STB ?? Kindly help me Solve this issue .
