Topic # 75057 12-Jan-2011 08:50 Send private message

For the last month or so my TiVo HDMI signal has been dropping and re-establishing once or twice a night [or 5 times on some days]

The screen goes black, then I get a screen full of multicoloured [but mainly white] pixels and then the picture comes back and my TV diplays the input settings in the top right corner as though I had just switched to that input.

Not a huge hassle but annoying none the less. Seems to happen more often than not just after the ads have started during One News although that is probably a coincidence more than anything as it also happens at other more random times. If I miss anything I can always skip back on the TiVo for the 5 or 6 seconds I missed.

It has done this on both fixed 1080i and 1080i hybrid settings.
I have rebooted also.

Tried a different HDMI port?

I am fairly confident on the cable as it was the 1-out from the 3-In/1-Out HDMI switch box so the PS3 and the DVD player also used the same cable between them and the TV and neither device had any issues with signal drop-outs.

I will swap the cable for another one I haven't used for the TiVo just in case it is a combination of that cable and the TiVo and see if the issue is still there.

As for the port, I will try the other one for the same reason as above but as I said in my OP, there is no signal issue with any other device using that port.

Thanks.

It could also be the switch itself, remove it and run the TiVo direct to the TV for a while.

I must have over edited my first post as I originally mentioned that I removed the HDMI switch from the setup and plugged the TiVo directly into the same socket but it still happens.

I have the same issue. It sometimes loses signal for up to a minute before reacquisition I hope someone has a fix!

I have never had anything last that long. Mine is literally off and on in the time it normally takes for my TV to aquire and display the signal. Maybe 3-5 seconds.

Did your's start out with brief stops before it became a minute?

I got TiVo 4 days ago and had issues using HDMI right from the get go with my old Samsung 32" LCD TV. There was the 'Mode not supported' message on the screen when the TiVo device is powering up which goes away once it's fully booted. But then there's the intermittent 'Signal loss' when watching Live TV. Turning the TV on and off fixed the Signal Loss issue the first few times but later on I had to power on and off the TiVo device to get any video output again.

I'm sure there's something going on with the HDCP handshaking on these two devices that I have so I just gave up on the whole HDMI thing and used component. So far so good.

Hmm, I have a Samsung 42" Plasma TV (720p) and I always get 'Mode not supported' at power up, and intermittently get a 'signal loss' of a few seconds when watching live tv too. It's been doing it to me since day 1 almost a year ago, but now come to think of it, it hasn't done it in ages.

Hadn't bothered to try another HDMI cable, since I don't have another one, but it all worked fine when I had MySky back in the day and that was connected by HDMI.

Actually i never thought of that, I have a nice fat set of QED component leads at home doing nothing. I will swap out the HDMI for these and get on with my life.  Hopefully it is just a handshaking thing and not a sign of a failing machine.

Two questions I guess...

Is this a Samsung TV acceptance thing?
Does TIVO (being non freeview approved) do HD out via component?

Jaxson: Two questions I guess...

Minigopher17 says he is using component without any issue so I guess yes is the answer on that score.
I have a Pioneer Plasma myself [43" PDP-436XDE]. It is 5 years old now but it still has one of the best quality pictures I have seen on either Plasma or LCD so I have no desire to change it other than to get a bigger screen but it would have to be a stellar picture quality.

I did some reading elsewhere and other people suggest that I might need to power down my TiVo [unplug etc] to reset the HDCP. I will also do the same with the TiVo before resorting to Component, although the HDMI and Component should be the same as far as picture goes, I would just lose the HDMI audio passthrough.
Also they suggested turning off any TV powersave options as this can send the wrong info to the HDMI and cause handshaking to reset in some cases.

I'm pretty sure component is SD only.  Also I think I remember reading somewhere how some Pioneer models have handshaking issues.

I have both connected now and have been flicking back and forth between the inputs and the picture is pretty close on both with the HDMI only very slightly better on an HD source but I have component going in and out of my AV receiver so I don't know if that has any bearing on it.

Micro-loss of signal is a known TiVo issue and I am sure there have been other threads on this. Have a play with the TiVo output settings, you need to find one that matches all your components capabilities.  That said while I have managed to reduce the frequency of mine, they still occur now and again...I have learnt to live with it.
