First, I want to say thank you to anybody reading this. I have called Geek Squad, Vizio and Denon technician who recommended me to ask for help on this forum. I have no other place to go anymore. I've combed over this forum and many other websites to no avail. I've been saving a lot of money to complete my little dream project and I am so close but frustratingly so far away. I have M65 4k Vizio TV, Denon S710 Receiver and Monoprice 5.1 speakers (I added two more of the same to make it 7.1). I am not able to set up the audessy as the receiver goes in to the protection mode. It happens on the first step and shuts off when it comes to the sub woofer. Moreover, my left surround speaker has much lower volume than others. I've checked wires, changed them, I am just ready to give up. My speakers and receiver work without audessy setup, but only at 50% because if I turn the volume any higher, it automatically shuts off. I read many reviews and the things that I've purchased were highly recommended by other users and people alike. Please help if you can. I've been trying to make this work for 2 weeks now. Last night I was trying to watch Jurassic Park with my niece and I had to keep volume really low to prevent the receiver from shutting down. I even drove 150 miles to freaking IKEA to buy the TV stand that I wanted. Well this is a cry for help as much as a venting post that I just had to write. Maybe the problem is in speakers, maybe receiver and maybe in the IKEA TV stand. I am by no means an expert and this is my first time setting this up. Maybe somebody encountered the same problem. Thank you again.
