Reboot needed after turning off TV
 

I had my Tivo installed today and it seemed fine when the engineer left, but then I turned my TV to standby while I went out for a few minutes. When I turned the TV back on, all I got was a blank screen and no matter what I pressed on the remote (TV, Home etc) nothing changed neither did selecting any of the other HDMI inputs - which was no surprise as it was already correctly selected The only way I could get it to work was to cycle the power using the switch at the back of the box. This has since happened every time I have turned the TV to standby for anything more than a brief time :confused:

I have phoned Virgin Media and they have arranged for an engineer to call on Saturday, but it would be nice to resolve this before then if anyone has any ideas what could cause this.

Have you tried putting the Tivo into standby and then back on again, when you get no signal?

I've had a similar problem when watching a blu-ray and then trying to switch back to cable all I've got is a blank screen. Switching box to stanby and back is the only solution. All HDMI connected by the way.

Yes I have, and I also tried putting the TV and the Tivo in standby and turning the TV back on first and then the Tivo, but to no avail. I tried this because my my (JVC) TV takes quite a long time to warm up - about 20 seconds.

Sounds like a tv handshake issue, I dont think the engineer could sort it. Switching off HDMI1 and back agian should bring the picture up

Re: Reboot needed after turning off TV
 

If you have another hdmi lead try that and in a different hdmi slot on the tv. If you dont have another hdmi lead just try the same one in a different hdmi slot.

What actually causes this problem with HDMI?

Re: Reboot needed after turning off TV
 

It can be a combination of things, as hdmi is really fussy. Hdmi cable hdmi socket on TiVo or Tv or amp if you use one.

Hmm, that sounds like a plan - I'll try that later, although it is the same cable and slot that I've been using successfully with my V+ for some time. Worth a try though, thanks for the suggestion.

Re: Reboot needed after turning off TV
 

Well I've tried using a different socket in the TV but that didn't help, so I just tried a different cable but it still does not work properly. I have found that unplugging the HDMI cable and putting it back brings the picture & sound up. It also seems to be intermittent - every now and then it just works ok.

Update
An engineer came round this afternoon to look into this issue and initially said that he would just need to re-synch the hdmi signals, but this turned out not to fix it. He then tried another Tivo box that he had in his van (having just uninstalled it after the customer decided not to keep it) and that did the same thing, proving that my box was not faulty.

He believes it may be a timing incompatibility between my JVC TV and the Tivo. He took all the details of the TV and my Tivo and said he would report the issue, in the hope that a resolution could be found such as a firmware revision that would cure the problem. So I guess I'll just have to wait and see.

In the meantime he found that just turning off the mains switch on the TV, rather than switching to standby got round the problem - a much better work-around than unplgging & replugging the cable each time.
