bazza_g Posted October 29, 2008 Report Share Posted October 29, 2008 got an annoying problem developing with our TV, any ideas would be most appreciated Setup: Panasonic TH42PZ80, coming up to 1 year old with a SkyHD box plugged into it on HDMI1 and the PS3 connected on HDMI2. PS3 is turned off. Symptoms: whilst watching Sky, the TV goes black and the HDMI1 icon comes up in the top left like its lost the signal. I then have to select another source, then go back to HDMI1 and Sky is fine again? Does this sound like a prob with the TV or is the SkyHD box on its way out? (1 month out of warranty!). The Plasma has a 5 year warranty but having it taken away is a pain in the **** Quote Link to comment Share on other sites More sharing options...
CarMad Posted October 29, 2008 Report Share Posted October 29, 2008 I get the same with mine, SkyHD and Samsung TV. It sometimes doesn't happen for a week then 3 times in an hour no idea what it is. I suspect its Sky kicking out a dodgy signal the TV doesn't like and then it goes on pause. Quote Link to comment Share on other sites More sharing options...
Chav Posted October 30, 2008 Report Share Posted October 30, 2008 not sure if your panny has it, but displays often have a "signal lock" feature to fix the above - stops it looking for signals on other connects when there's a temp blip (as often happens with sky) Quote Link to comment Share on other sites More sharing options...
pontyslapper Posted October 30, 2008 Report Share Posted October 30, 2008 Its the dubious signal from the Sky box. Our LCD does the same with our Sky+ box - flickers like you're changing input and sometimes knocks itself off. Definately the Sky box as it didn't do it with the old 'regular' Sky box. There's a whole raft of FAQs on Sky about it - Press the following buttons on your remote -> Interactive > Sky Active > Q&A or A to Z and you'll find them soon enough. Whether they help is a different matter! Quote Link to comment Share on other sites More sharing options...
Tipex Posted October 30, 2008 Report Share Posted October 30, 2008 Our Sky+ box doesn't do it, but the Sky HD box does, very annoying. Quote Link to comment Share on other sites More sharing options...
bazza_g Posted October 30, 2008 Author Report Share Posted October 30, 2008 cheers gents, I'll check those FAQ's - sounds like the same thing as it sometimes doesn't do it for a couple of weeks, then does it 3 times in an hour Quote Link to comment Share on other sites More sharing options...
Biscuits Posted October 31, 2008 Report Share Posted October 31, 2008 What HD output setings are you using. I've never had a problem with the HDMI output of my SkyHD or Sky+ boxes. Make sure your not using AUTO, but fix it at 1080i. Adverts and programs are at different resolutions and aspect ratiops, so your tv will try and change if you don't have the output fixed. The TV's I've used the SkyHD box with are a Toshiba 37" LCD and the current TV a Pioneer 428XD. HTH Quote Link to comment Share on other sites More sharing options...
bazza_g Posted October 31, 2008 Author Report Share Posted October 31, 2008 cheers, will check the sky box output res tonight Quote Link to comment Share on other sites More sharing options...
gizze Posted October 31, 2008 Report Share Posted October 31, 2008 Same here, 1080i seems to be the best picture all round, not normally a fan of upscaling when the display is going to scale again, but 1080i works best for Sky HD and I have never had a problem with it loosing sync.

craigyb Posted November 2, 2008 Report Share Posted November 2, 2008 Me too, always had it set to 1080i Had a few issues with C4 and flicking through channels, particularly C4 would cause it to crash/lock the box up. This seems to have stopped now though. Only thing I have to contend with is the terrible lip sync with HD channels Quote Link to comment Share on other sites More sharing options...
gizze Posted November 2, 2008 Report Share Posted November 2, 2008 I have adjusted it so the sync is not noticeable for 99% of the time, think it is about 120m/sec on the sky box, this means the regular is slightly too fast and HD is slightly too slow, but not noticeably which is the important thing.

craigyb Posted November 2, 2008 Report Share Posted November 2, 2008 Yes I also have 120mS set for teh audio delay, but it's still dreadful for HD, it seems to vary with prgrams, but BBC HD is unwatchable for me, the audio is about 250mS out.

gizze Posted November 2, 2008 Report Share Posted November 2, 2008 I must admit, I went to a Pioneer 508XD for a few weeks, and I had all sorts of problems with that and lip sync, so maybe it is the way the panels handle the deinterlacing etc.?

CarMad Posted November 2, 2008 Report Share Posted November 2, 2008 I've found the lip-sync on mine to be fine on HD. It does have a slight delay on Sky box and I've turn the lipsync on the Onkyo and it seems to work fine. I already had it set to 1080i so not sure why it drops off sometimes, part box part Samsung I guess. Quote Link to comment Share on other sites More sharing options...
