I had an Xfinity tech at my house for several hours last Friday to troubleshoot why I am suddenly getting sound but no picture after 15 years on two of my TV's connected via component. It looks as though Xfinity's unnanouced firmware update seems to have resulted in causing legacy boxes to no longer work with component connections. I don't know if that's the case with X1. We tested HDMI on the same non-working box and it appears to work fine (in my case it's not easy for me to swap out component for HDMI because the boxes and the TV's are on different floors). Xfinity does not have a fix. In fact, the service tech who came out managed to slip out of my house without so much as a whisper after he failed to fix the problem. Since then I have unsuccessfully tried to escalate this to to Tier 2 tech support to see if maybe an HDMI to component converter could be a work around. Rather than be connected to Tier 2 support, I have been thrown into an endless loop with Xfinity's Philipino call center telling me "Oh, I'm so sorry for your problems Mr. Don, but first we need to to start all over troubleshooting the problem. Please can we refresh the boxes now, Mr. Don blah, blah blah.......?" Ater the 10th time I have given up and am waiting for delivery of a converter I purchased to see if it works. Supposedly some Xfinity stores have component to HDMI converters readily available and "they're free" (according to another tech I spoke to somewhere behind the Iron Curtain). Not according to the store near me - the employee looked at me like I was on drugs telling me he's "never, ever heard of this". I will repost with the results of the converter.
