upc romania is broadcasting hd at 720p
Hello Codrut, are you sure is 720p?
On rds romania, if I press Ok to see info, on HD it says 1080i. This is true also for ProTV HD directly (freeview, or antena, so not cable).
So, is it 1080i or 720p ?

i see you've mentioned 'discrete 5.1 sound', why, is that not 'real' 5.1?
also, yes, upc romania gives hd at 720p - does this mean i wont be able to use the lh5000 to it's full 1080 capacity? the stb does provide for a setting which says i can choose between 720p and 1080p (or 'i', i dont remember) - i've chosen the 1080, does this mean that even though the broadcast is at 720p, the lh5000 will upscale it to 1080?
discrete... we'll have 6 separated channels; matrixed (for example, pls read here: Dolby Pro Logic - Wikipedia, the free encyclopedia ) we'll have two channels for simple amplifiers - and three more encoded within, which can be decoded by dd amplifiers, etc.
as for signal, the stb probably will upscale to 1080i (there is another member of this forum - Maximus9 - which asked for details). i don't have a upc box, so i must rely on technical data provided by one of technical guys from upc. i think you could play a bit with stb settings, maybe there is an option to send original signal over hdmi and not upscale it - and see what the tv says.

are you by any chance romanian (codrut) ?
i'd say it's a very good chance...i'll bet on it ;)

just to check a previous setting suggested by you, i took off the optical cable from the tv and plugged it into the stb - so having now optically connected the pioneer directly to the stb.
what ive noticed is that, if with the previous optical connection in the display of the pioneer i had only "pcm" showing - no matter what tv channel was being broadcasted - , with this last 'check' optical connection i get "dolby d" in pioneer's display, at some of the tv channels (some still remain with that 'pcm' on the display).

so apparently yeah, as you said previously i was 'overkilling' stuff, and the normal connection (at least from pioneer's "view") is this latter one i am trying now. also i think when 'dolby' is shown on the display, the sound really sounds like i was expecting it to

or is it just self-suggestion?
well.. isn't self-suggestion, for sure. that's how they intended the sound to be heard.
but if you're connecting stb to tv via hdmi - which kind of audio signal the tv will report (i'm referring to previously tested dd channels)? pcm or dd? changing stb audio settings will affect this?
and if it's about dd detected by the tv - is this signal sent further unaltered via optical output of the tv, to amplifier? will the amplifier detect dd, finally?

"i'd say it's a very good chance" - cool, it's good to know :) - me too, i'm from iasi (probabil e mai bine sa vorbim in engleza aici)

well, the display of the stb only shows the name of the channel being broadcasted, no info on sound. that 'dolby d/pcm' only appears on the pioneer(dvd/amp) display. actually i notice there are only 3 channels(hbo hd, national geographic hd and u tv hd) when 'dolby d' is displayed, all the rest(hd or sd) show 'pcm'. just to double check, i took off the optical cable from the stb and connected it back to the tv - and the pioneer amp displayed pcm instead of dolby d (on those 3 hd channels). it makes sense, as when being optically directly connected to the stb, the pioneer amp 'knows' better what type of sound is being relayed.

so pretty few channels broadcast with dolby sound. i think i've seen yesterday the 'dolby d' notice on the pioneer amp also on eurosport hd, during a broadcast of the european bar bells(haltere) championship(on the tv screen there was also 'native hd' shown in a corner) - but i'm not sure.

the tv is connected to the stb (and to the pioneer amp) by hdmi anyway, all the time. but if i disconnect the optical cable, i dont get any sound at all from the amp (at least not from the 6.1 amp speakers - i do get sound from the tv speakers though(but i dont use those anymore)).

so: the pioneer amp detects dolby d only when it's optically directly connected to the stb. if i optically connect it to the tv, it doesnt detect it (at least the pioneer amp's display only shows 'pcm'.

about the cisco stb(from upc): it only offers 'volume' and 'audio-hdtv sincronisation' as audio settings. as about the hdmi resolution, it offers the choice among: 720p, 1080i and auto. i keep it on auto, as i believe this automatically switches resolution depending on the 720p/1080i type of signal it receives (is this right?)

In my case (bucuresti, rds), I get 1080i on info screen on all HD channels. I dont use a STB, I use the built-in DVB-C tuner. It;s also 1080i on HD got by antenna (freeview, free-to-air or how is it called).

Not related to anything, one thing I noticed: if I select THX Cinema mode (I activated it from the secret menu), the Aspect Ratio automatically changes to Just Scan (instead of the Original) in case of a HD channel.

I have a big problem: the daylight saving time in Eastern Europe changed the hour... but this TV does not allow us to change the time. I managed somehow to change Time Zone to GMT+3, now the TV time is correct, BUT the EPG is not right (always one hour back)!!! This is really stupid and annoying. I could do a full rescan but then I would have to go again through the painfull process of arranging 100 channels...

Did someone found a solution to that? I mean, at least codrut and alecsu should have the same problem...

<Maximus9> right, i've forgot about that lg tv info. i've checked now by pressing 'ok' on the lh5000 remote control on different channels, and this is the info displayed on the screen: on the 9 hd channels it says '16:9/1080i/50hz' (additionally, at those 3 hd channels where 'dolby' is displayed on the pioneer amp, it says 'dd'); on the other channels(at least those i've bothered to check) it says: '4:3/576p/50hz(with the exception of pro cinema, bbc world, mezzo, m6, dw-tv, rtl, pro7, duna and probably others which now show 16:9 - i have the lh5000 image set to 'original' so probably it switches between 4:3 and 16:9 depending on the broadcast)

on the stb(cisco - upc) i've set the resolution to 'auto', so it auto-switches between 720p and 1080i depending on the original signal.

as about the time problem, i have the time displayed correctly by the stb - i never used the time option provided by the lh5000. if i want to record something and so make a schedule, i also use the timing from the stb.

i think this will answer all the questions. rds will broadcast in its own way, upc also.
but going back to the dd sound on provided channels... if the tv detects it correctly as dd, shouldn't make passthrough over spdif unaltered , so the amplifier finally decode?
as for other digital tv problems... i'm afraid that i can't answer; i don't have the equipment nor the necessary signal :) - just playing with a egreat eg-r1 nmt and internal tv player. because that damn dts problem!

Codrut, what DTS problem ? Doesn't egreat eg-r1 downsample dts to stereo ? is'nt the problem solved? I want to buy the same nmt or maybe Media Player iTab48R which is more evolved and has recording.
BTW, with a tv like that, you should really get some digital cable (rds, upc).

i'm reffering to lh5000 series tv - no dts at all. egr1 has it, i'm using it to play dts sound, etc.
as about digital cable, for what? seeing romanian tv stupidity? no, thx :)
documentaries, you may say - but how about some .torrents? :)
let's keep, anyway, the topic for just about lh5000 ;)

Hi,

I just bought the LH5000 and for some reason the buttons from the right side panel don't seem to work although in Menu / Option / Keylock is turned off.

I'd like to solve this as it prevents me from accessing the hidden menu with the OK (remote) + OK (TV) command.

Do you have any idea why those knobs won't work?

no idea, i have checked mine and they are functioning ok. maybe you should contact the seller, or directly lg.

on another matter: just noticed lh5000 doesnt play avi files on usb stick/drive. any idea how should i fix this? maybe a software upgrade might help?
