I have noticed that lately I have been getting grey screen or no signal screens . It last for a few seconds. It only occurs in the evening.

Any ideas?

Sounds like a signal strength problem. Humidity goes up in the evening, and perhaps that is enough to reduce your signal to the digital reception 'cliff'. Why they ever wrote the TiVoHD software so that it grey-screens when there is no signal, who knows, seems like poor programming to me.

I think there are two separate issues here.
When we had the stormy weather in Auckland a couple of weeks back my Tivo had the grey "no signal" screen too. My guess is it was a Freeview HD issue rather than Tivo.
But what I do get occasionally is a few seconds of "No signal" screen which either goes away on its own or requires me to cycle through TV inputs until I get back to the HDMI input I use for Tivo. I guess it is a HDMI issue.

I get it only in the evening, I can flick channels on the TIVO and it will come back. All I am getting from TIVO support is what seems to stalling questions and little actions. I am not impressed.

My TV has inbuilt Freeview HD and that has no issues what so ever.

The signal strength on the TIVO is very good.
I am using a 1.3 HDMI cable
My Samsung TV is HDMI 1.3

a question,
do you have the video output format fixed or is it autodetecting which is the default.
I fixed mine to 1080i as it was blank screening when the signal changed at times.

I will have a look at this, it wasn't something I looked at in my diagnosis trail.

Thanks for that, will let you know the outcome

Have you tried pulling the power cord out to do a hard reset?

I presume you have checked all the cables.

Is your broadband connection on all the time? I had a wierd thing happen when I disconnected the Tivo from the network, no sound on any programs. Re-connected and all was good.

Those signal strengths are too high I think. It's likely the tuner(s) are being 'saturated'. For whatever bizzare reason, the TiVoHD can even crash/lockup with too high a signal strength. Try a UHF attenuator (say 6dB or an adjustable one), they only cost a few dollars.

After spending a long time on the phone to Telecom's Tivo Support and their CTS Support who in turn spent a long time talking to Tivo Support in Australia I am awaiting an email from Tivo Support in Australia with instruction for arranging a replacement Tivo unit.

Telecoms CTS unit were brilliant , they rang back several times exactly on time when they said they would. Very impressive.

I will keep posting here as to progress.

Tivo Australia would seem have forgotten how to use phones. Not a thing from them. Telecom are still being brilliant in their attempts to get Australia to front up.

I cannot believe that Tivo Australia can treat customers so badly.

If the TiVo was sold by telecom Nz they should surely replace it themselves if it's faulty under the consumer gaurentees act ? Or does it have to be replaced by TiVo australia ?
