My Cyclone is just over 1 year old, don't seem to be able to output via HDMI anymore. Can connect via component but obviously picture quality poor compared to HD. Originally the picture started cutting in & out. After jiggling the lead managed to get a picture. This lead me to presume the lead was faulty. On turning it on today can't get a picture at all. Have bought 3 new leads today (all £5 leads). The tv i normally use the Cyclone on get's no picture or sound. I've tried on 2 other tv's. I get intermittent picture & sound on both these tv's, the picture is very snowy. This a firmware or hardware issue?
My dad stopped getting a picture through the HDMI after he left the component leads in all the time. Removing the component leads solved the problem. Sounds like your issue is more serious than that though, but it might be a starting point.
