hdmi signal getting weak?

Have searched forums for this problem but haven't seen it mentioned so far. Several months ago my (652160) Tivo/Onkyo/Sony setup started a new behavior. When powered up (the Tivo stays on, of course) the picture would take several more seconds to show up than the sound. Was using hdmi through the Onkyo and onto Sony display. This was a minor nuisance until it got to become an unreasonably long time and then quit getting a picture signal (from hdmi) at all. I switched to component out and have been getting a signal but it's taking 3 or 4 minutes to show up.

First, Onkyo has a history of weak hdmi boards so I assume it could be the weak link. I'm still relying on signal coming in from the Tivo via component but then sent to Sony via hdmi cable. What doesn't fit with the Onkyo theory is that my DVD/Blu Ray player shows up immediately. And, I've switched cables and hdmi ports to test. No difference.

Added to this was a spate of recent rebooting. The unit still runs fine but occasionally reboots, mostly when I'm using it to stream Netflix or do something unusual.

Just replaced the hard drive (I wanted more recording time anyway) and that's all gone swimmingly. While having the Tivo apart I took a look at the capacitors and noticed one that was domed. None were leaking and no others showed any doming. Didn't have a chance to check voltage while there but, along with a further visual inspection, that'll be my next move.

I'm curious if anyone has experienced the hdmi signal degrading as a result of the caps going bad. Any experience with hdmi signal degrading otherwise? Hoping it's not a bad MB since it's a lifetime unit.

Thanks all in advance. Awesome being able to come here and learn.
