Hoping someone out there can help me out. I have only had this TV for 18 months and very little hours on it. First all 3 of my HDMI ports have failed, I now have to use video cable to get a picture from my cable box 
. The HDMI ports have gone over the course of owning the TV but last night I had no picture and now I have a trouble code 13 blinking from the red led light on the front of the TV. Doing some searching I haven't been able to come up with a manual to try and troubleshoot my problem. I do have the manual from my purchase but it doesn't tell me anything including why there is a red blinking light 
. What I have found from searching is possibly my DG board could be bad (not even sure which part this is)? I have tried following some links from other posts but haven't had much success.
