Yamaha RX-V571, anybody?

[newvirus2008]

I bought a Yamaha RX-V571 few days back, connected it to my Sony Bravia HDTV and since then the corresponding HDMI input on TV is not working.

I checked the TV with another HDMI source (HTPC), the result was like "Unsupported format, check input signal ". I checked the AVR with another HDTV and the result was "No signal". However I got a replacement from YAMAHA dealer against manufacturing defect.

Could there be any problem? I think I first turned on the AVR and then the TV which was in standby until then. I had two DVD players and set-top-box connected to TV at that time. Anyone else with same / similar problems? I haven't connected the new 571 to TV yet.

And, the 571 sounded too good for my speakers.
Fronts - 4x Philips FW326, 12 ohms (two nos. per ch)
Surround - Philips surround speakers (16ohms each, wall mountable)
Center speaker - NIL
Sub-woofer - JBL CS1215 in ported box (33Hz) with 100W (true) DIY amplifier. What can I do to upgrade this setup? I can spend up to 10k for 7 channels.

Thanks.

how I can avoid such problems in future ?

Although I'm an engineer I am new to this HD world and have problems understanding the requirements (protection etc.) of today's equipments.

Am I missing something important ?
Could somebody please suggest a possible solution ? My AVR is still in the box

Thanks.

Hey,
Were you able to solve the issue?

I got an MX spike-buster power strip (2500W) and powered TV, AVR, DVD and computer into it and got the AVR working as expected.

Another thing I did was turning off the square-wave inverter backup for my house. I also turned off my set-top-box for cable TV while using the AVR.

Both TV and AVR were blown which is why I suspect the power supply.
Now the setup is working but I am still not quite sure of what happened at that time.

Few things the 571 safety manual/pages mentions :-

1. Over-all the want you to connect everthing to AVR then turn its power on. Be it speaker or any other external source.

2. The speaker wires shouldnt touch any metallic portion of the AVR, though that should not interfere with the TV which was your case.
