Series 3 Disconnects and makes loud noise

On 3 to 4 occassions including this morning I came downstairs and turned on the TV and the series 3 TIVO had disconnected and was making a very loud noise. I promptly unplugged the TIVO and plugged it back in and it rebooted and everything is fine. This issue occured 2 days in a row and previously this occurred maybe 4 months ago. Any thoughts on the issue?

Maybe dust accumulation on the cooling fan parts. Or hard drive starting to fail.

"Disconnected?" From what?

The TiVo was making a loud noise through the AUDIO path? Or just making a loud noise itself (ie, coming out of the chassis)

The TIVO was making a loud beeping noise through the audio path on the TV. When unplugging the power cord from the TIVO and plugging it back in the sounds stops and TIVO reboots.

My new Tivo HD just did this today. I don't know why. I have only had the Tivo about 10 days now and I went to watch tv. When I turned on the TV it was a blank black screen and it was just making a loud beeping. It was unresponsive to the remote and my only option was to unplug the Tivo.

It appears to be fine but since I am in the 30 days still I am wondering if I should exchange it in the store especially since I can transfer lifetime easily online.

The other thing is when I ordered lifetime originally it took like 5 days for this box to pick up the fact it has lifetime even though the Tivo website showed it the next day. I didn't have this issue on the other Tivo HD either.

I've had this a few times on my HD TiVo. Sounds like a high-pitched beeping noise that beeps at a pretty high rate of speed. Yanking the cable, and rebooting the box does the trick, but I'm hoping it's not an indication of future problems.

Has anybody isolated what the cause is, or have any idea how to prevent it form happening?

Many TVs respond to audio signals they do not like by emitting high-pitched, screeching sounds. If using the TiVo direct to your TV, be sure to set the TiVo to output PCM under Settings -> Audio -> Dolby Digital.

The TiVo is supposed to detect whether your TV can accept Dolby Digital (most cannot), and then automatically send PCM if requested by the TV. However, people have found that at times, the TiVo was not able to detect that PCM was needed, so it briefly sent a Dolby Digital signal. Some TVs responded to that Dolby Digital signal with a high-pitched screeching sound.

I'm not suggesting this is the only cause, but it is one that people have identified in the past.

That's only with HDMI connections, right?

Correct. You can rule out HDMI as the cause by disconnecting HDMI and temporarily using component.

Component will pass the HD signal just like HDMI. Just be aware that most televisions save separate display settings for HDMI and component, so if you tweaked the settings for the HDMI input to obtain a better picture, then you would have to do the same thing on the component input.

That may very well be true, but the main problem is that the TiVo is crashed and completely locked up. It won't even flicker the yellow light to indicate that it detected a signal from the remote. Getting the audio settings right is not a high priority at that point.

I've experienced this myself a bunch of times in the last year or so as well. I have no idea what causes it or how to prevent it.

For a while it happened once a week, then it would go a few months between instances.

Two nights ago it happened (after not happening for a few monts) and this was the first time it happened while I was actually watching it. The whole screen had some pixillated flickering for about a second, and then the screen went dark and the beeping started and the TiVo was completely unresponsive and required a powercycle.

Interestingly, about an hour or so before this happened, again while I was watching it, the TiVo spontaneously rebooted itself.

This thread suggests that it might be from the cable signal strength being too high: http://tivocommunity.com/tivo-vb/sho...d.php?t=418924
