Advertisements This just started happening today. Tivo Bolt HDMI going through a receiver to a TV. HDMI link disconnects and reconnects. Normal lights stay on on the face of the unit the whole time. I have ruled out the external power adapter. I swapped out another one and the problem stayed on this unit. The TV and receiver are fine. It could be the HDMI cable from the Bolt to the receiver, but note that the problem goes away for a few minutes after a reboot (even more when I let the Bolt sit unplugged for a whole) then returns and gets worse and worse. I suspect overheating based on the symptoms, but where? Are there any other troubleshooting steps I can take? The problem happens on the home screen (i.e., when the HDD isn't playing anything back), so I think that rules out the HDD. I just tried firing up Youtube, and the screen went blank for quite a while. When it came back (eventually), I was able to watch for around a minute before the HDMI signal dropped again. So, really doesn't feel like the HDD. Could it be the HDMI port? Motherboard or equivalent? Where do these things generally have heat-related problems other than an HDD (and now that the power supply is external)? Thanks for any help you can provide. I did try looking through the forum, but didn't find anyone experiencing similar symptoms. I doubt this is a unique case, though. One other thing to mention is that we had some lightning strikes nearby today, but could that cause a somewhat failing but not 100% failing component like this? I guess so. Either way, I think that's everything I know about the problem.
