Can a power outage cause DVR to Onkyo sound to fail using HDMI inputs?

[dshiba]

I have an Onkyo HT-R560 receiver 7.1 system. I have a Samsumg LN52A750 flat screen TV. I also have DirectTV. So I hooked up the surround sound using HDMI cables running one from DVR to Onkyo, and then one from Onkyo to TV. Everything was fine until a recent power outage. I do have surge protectors, although one was older than the other.

Anyways, the TV said 'no signal'. I swapped out DVR's, swapped out cables, and nothing works. The DirectTV guy said the outage must have blew a chip in the Onkyo so that now sound won't work with the DVR only. HOWEVER my surround sound works the radio, CD's, iPod, etc. - just not regular Satellite TV through the DVR. I can also run a cable directly from the TV to the DVR and the picture is fine, but then I can only get sound through the TV and not the Onkyo.

Help! The guys said 'buy a new Onkyo', but that's not what I want to hear and I have to think there is another solution.

If nothing works via HDMI through the receiver anymore, then probably your Onkyo either needs to be serviced or replaced. The fact that other things that are not hooked up via HDMI work does not prove that there is nothing wrong with the Onkyo. Have you tried using a different HDMI input on your receiver?

First do a system reset on the Onkyo.

After a power disruption that might work.

However it is quite likely the repeater circuits in the Onkyo are down.

Do you have another source such as BD player to test the Onkyo? It might be the Direct TV unit that has failed.

There is no repeater architecture involved going direct from a device to TV. There is going to a device like a receiver that receives and outputs HDMI.

Surge protectors are virtually useless.

You need whole house surge protectors and a battery backup UPS that will isolate your fragile equipment from the grid in around 1 ms in the event of power being out of spec.

Cheap surge protectors are no protection for fragile modern microprocessors.

Thanks for the Advice

Thanks TLS Guy - I will try testing through a DVD player. I have two Direct TV units and tried them both so I know it is not that. I will do a system reset on the Onkyo too. I'm not familiar with repeater circuits - if that is the case, would that mean 'I need to replace the whole Onkyo'?

A TV makes one initial handshake. A receiver since it inputs and outputs HDMI must make repeated continuous handshakes with connected units. The DRM HDCP codes are much more rigorous.

If it is and HDMI failure in your receiver, the HDMI board will need replacing. This is a costly repair, and there may no be much daylight between a new receiver and a repair.

Try a reset first, as if the firmware is just messed up, the problem might correct after a reset. If there is a hardware failure it won't.

It Works!

Thanks TLS Guy - I did a system reset and then just repogrammed my HDMI inputs and it seems to work ok. I guess I should have tried that in the first place, and definitely should not have listened to, or assumed, that the Direct TV guys new what they were talking about. REALLY appreciate it!

I'm glad you are sorted out.

It just goes to show you have to trouble shoot in a logical manner.

Your system took a nasty hit though and you are lucky.

Now set about getting decent protection.

Decent protection as in a battery back up like we have for our PC/Server the wife has for her Bussiness? It last about 30 minutes, long enough to shut down and Un Plug when power fails and if storms are coming. Another big question on protection from lightening strike. I unplug everything.

You're only safe when you can completely detach the power. All the hardware you can buy only works with fairly minimal surges, like in the hundreds of volts, like what happens when the power blinks off and on. When lightning hits nearby, you get hundreds of thousands of volts and it will arc right past your surge protector, zapping any chips in the voltage path. A few years ago, I lost 2 TV's, a surround receiver, a PC, DVD player and a cable box in one quick second. Lightning hit a pole about 200 feet from my house and all the electronics that were plugged in were dead. Lights were still on in the house, Air running, but chips were all dead.
