Hi all, I'm trying to solve my HDMI issues, and starting to get frustrated. I appologize for the long post, and thanks to anyone that makes it all the way through.

I had a Monoprice HDMI switch (http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10110&cs_id=1011002&p_id=4066&seq=1&format=2) being fed signal from an Xbox, a satellite receiver and a Sony BDP-S300 blu ray player. I am running a 35' Monoprice cable (http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10240&cs_id=1024005&p_id=2742&seq=1&format=2) out to a Epson 1080UB.

Occasionally, all the lights on the front of the switch would turn red and my Epson would show No Input. I'd wiggle the switch around, and the signal would come back. It was very positional, the switch liked sitting with the front slightly raised. I thought it was an issue with the switch. This happened on all inputs.

My wife bought me a PS3, so I connect it through the switch. The PS3 menu blinked on and off, which I assumed was a handshake problem. Unplugging the cable and trying another input on the switch would sometimes solve the problem. In game, it was perfect. Never an issue, except for the aformentioned signal loss problem.

I decide I've had enough with the flakey switch, and upgrade my receiver to a Denon 2809. Get everything connected, and as I'm setting up the speakers, it's losing the video signal. To fix the issue, I'd have to unplug the 35' HDMI cable, and power things off, replug and carry on. I finally got what I thought was a solid connection. Ran through the set up, tried it on all inputs, had one issue with a short drop while using the blu ray, but it was a short loss. It seemed solid for several hours. Then, found my brother online for a little hockey. About 2 minutes in, I lose my video again. No Input displayed on the Epson.

Are these common symptoms of a bad cable? It is pretty thick cable, and It's pretty tight coming out of the back of the 2809. Would my first step be to buy a short flexible cable and a coupler to try and take some strain off the connection out the back of the receiver? Could it be the Epson? I'm getting sick of replacing things, and it's an expensive way to try and troubleshoot. I'm to the point that I don't even like using the theater, because I'm just waiting for the next problem.

Thanks again for any help!

This is a major problem and can often happen with HDMI. First things first, its always a MUST to connect all HDMI connections with the power OFF. Then one at a time turn on one source at a time to allow for correct HDMI handshaking to take place.

If you still have problems, its best to then check every HDMI cable one at a time and see that it works by direct connection from source to display. Its a long slow procedure but its a MUST. One by one test each cable to make sure that they are all OK, again connecting with power off, then power up!

If all the cables are OK, there might be an incompatibility issue with the switcher you bought, the next step is to try a different brand.

With all this "stuff" often the most expensive doesn't mean it will be any better than a cheaper one, they either work with your set up or not. You will find an answer in the end, everyone does, but it can and often does take allot of detective work.

Be patient, you will get your system up and running exactly the way you want it in the end!

Good luck :)
