Hi,
Interested in any feedback, thoughts or similar experiences...

We have a Tivo connected via an HDMI cable to the Sony TV (KDL-40V4000). On a regular (daily, twice daily) basis the TV stops displaying an image for a few seconds then comes back. It appears as though it is trying to change resolution (?) - but I can't see why it would be doing this.
I have tried a second HDMI cable but the problem remains.
As far as I can tell, it does not do this on normal live TV however it would also be fair to say we view very little of this.

Anyone else seeing this at all?

Cheers
Neil

Hi,

Had the same problem, brought a new $25 HDMI cable from an local online supplier,

Haven't had the problem since.

You could aso try setting the video output to one of the fixed options rather than native or Hybrid

I've tried two HDMI cables - though they are the same type - but I have fixed the output option. Hesitent to spend much more on HDMI cables unless this is a likely fix... thanks for the feedback tho...

I'd pick it being a HDMI cable issue.

How old is the TV? There could be newer firmware upgrades for the TV if it's an older Sony.

Coming up on a year old ... I have it set to download new firmware... But don't know if it actually does.

Lunar7 - out of interest where did you get your $25 HDMI cable? Do you recall the type?

Have a look at http://www.rapalloav.co.nz/product/1552/HDMI---DVI/HDMI-Cable/

I was really sceptical that it could be the cable so didn't want to go over board...

Funning this is I'm now using the old cable on my PC and it works + I think has improved the picture on the monitor over DVI ?????

HDMI won't give you a better picture than DVI (assuming it was a DVI-D connection and not DVI-A) - it's using exactly the same signal.

If the cable brand itself is bad ordering a 2m one isn't necessarily going to solve the issue.

Well, unforetunately a new HDMI cable made no difference... Problem continues... Any other thoughts or people with a similar issue?

To recap the problem;
We have a Tivo connected via an HDMI cable to the Sony TV (KDL-40V4000). On a regular (daily, twice daily) basis the TV stops displaying an image for a few seconds then comes back. It appears as though it is trying to change resolution (?) - but I can't see why it would be doing this.
I have tried a second HDMI cable (and now a third) but the problem remains.
As far as I can tell, it does not do this on normal live TV however it would also be fair to say we view very little of this.

Thanks

Neil

Does your sony tv have an auto detect on the hdmi resolution.
It could be that ?
If so set it/lock it to the highest resolution it can take and see if that makes a difference.

None that I can find in the menu settings... I'm thinking it's a Tivo issue now since it only seems to occur when watching this...

So you have tried setting the Tivo to a fixed resolution? The format button on the front allows you to select one (or you can use the settings menu).
