Re: New Members - please post your introductions here

Hi Everyone,
I'm here to ask help regarding my Samsung Curve UN65HU9000FXZA.The standby led double blink 5 times when I power on the tv but when I unplugged the one connect box (BN94-07652Q) the power stays on but no sound and no picture. I have a little background in electronics but I'm not sure which part is to replace. The mainboard (BN94-07049Q) or the Samsung one connect box? Thank you very much for all your support and may God bless this forum!
