Denon AVC-X3700H Losing Signal when I puths the Volume high.

[onelife2000]

Denon AVC-X3700H
5.4.1 Setup - Fronts, Centre, Surround, Ceiling Centre, Ceiling Back
Wall - Polk RC65i - Set as Small in the settings
Ceiling - Polk RC60i - Small
Centre Signature Elite ES30 - Small
Sub - Boston Acoustics Soundware XS
TV - LG G1 65

Apple TV > AVR > TV

No Video Processing on

So when I ramp the sound up beyond 60% on the AVR the Picture cuts out.

I've done the Audyssey setup and the centre was very loud compared to the Wall speakers and the picture back to the TV is cutting out there too. I don't know if the Centre should be considered a Large Speaker but can't seem to change that speaker separately to the Fronts/Back

Any Ideas?

Worked it out:

My Centre speaker wires were extended by just twisting together for testing and I left them loose behind the Wall void so they were shorting out as the volume cranked up either too close or shorting across the Plasterboard.

Now I have crimped them. Boom - it can go loud!
