We have AT U-verse and we lost power during a storm. The picture returned and sound through the tv speakers but our surround sound did not. We have an Onkyo receiver along with the U-Verse cable box but nothing was changed.Any ideas?
That used to happen to me too, quite frequently. What happens is when the power goes out, the receiver looses its settings and goes to a default mode. You have to go into the setup menu and reset all the values so it recognizes that all the speakers are present. I say this USED to happen because the power used to to go off if someone down the block so much as sneezed hard. We rarely went more than a week without a failure. Then Hurricane Sandy blew through and tore things up, including the power lines. It took more than 10 days to fix it but they apparently fixed all the weak spots - we haven't had much more than a blip since. Of course, during that 10 day period I went out and bought an array of batteries and a power inverter as well as a generator - which are now pretty much useless.
Most likely the receiver is on the wrong input
How is your Onkyo receiver hooked up? Chances are your Onkyo was reset to factory and you have to choose the input from your TV/Uverse. box. Or your TV got reset and is not sending audio out the optical cable to your receiver. Same problem but with the UVerse box.
There is a chance a surge may have damaged some components in your receiver. Power Surges are brief spikes of abnormally high voltage spikes (excess electricity) that can cause immediate damage to sensitive electronics. Surges can be caused from lightning, the utility company (coming in through your breaker box) or electronics with-in your home such as a vacuum, spin cycle on the washing machine etc... Surges can enter your home through your cable line as well and damage anything connected to it cable box, TV, surround sound connected to TV or cable box at the time of the surge... You can prevent this by installing a cable surge protector on your cable line and using a surge protector strip to plug your entertainment system into so the surges will damage these items instead of reaching your electronics and causing you all this hassle. If storms seem to cause this scenario often you could look into getting phone protection as well as a whole house surge protector on your breaker box.
how have you connected U-verse to the amplifier? hdmi? which Tv model are you using?
