TX-SR508 Blueing Screen

I have a Model TX-SR508, great unit when it works correctly. It is 8 months old and since new it has been having the same problem. While watching Telivision the screen will go blue, sometimes it will just flash blue and others I have to turn the unit off and back on to get he screen back. This happens with Cable Box and Blue Ray. The Unit was professionaly intalled. It has a 30' HDMI Cable from unit to TV. My installer first thought it was the HDMI cable so he replaced it that did not work so then blamed my TV. I have unhooked the Onkyo unit from the system and am watching HD Cable and no blue screen so I know it is nothing wrong with the TV. Now the installer is saying that the HDMI Cable that he installed is to long, I think he is making excuses. It would cost me a lot of money to relocate my equipment. Could someone shed some light on this?

Thanks,

Brad

Hi Brad,
It is possible that the length of the HDMI cable could be causing the problem. We have a blog post with an HDMI checklist that may help you troubleshoot the issue. http://onkyousacustomersupportblog.wordpress.com/2011/09/13/the-hdmi-checklist/
The 3rd step on the checklist is a factory reset if you decide to do that here is all the information you would need to know: http://onkyousacustomersupportblog.wordpress.com/2011/09/12/factory-reset/
If you have any other questions please ask. Thanks for choosing Onkyo!

Thanks, I will try the Booster. If indeed it is the problem; should I run a short cable strait out the unit put booster inline then the long cable?

Hi Brad,
You can use the HDMI Booster with the current HDMI Cable that you have. Thank you for contacting product support.
