LG PG7000 thread

MSF · 16-01-2009, 11:41 PM

I have seen some sort of picture noise on my PG7000 when I have static images on the screen.
For instance when there is no signal and "NO SIGNAL" is floating around the screen, if I look close at it, there is "noise" in the "NO SIGNAL" 'rectangle'.
Sorry I can't describe it better.

Now the weird part, If I turn on my BR player and set 24p to ON, the plasma will change resolution like it should and when the picture comes up there is no sign of the noise. I turn off the BR and the "NO SIGNAL" comes up and is clean winth no noise at all. Changing to other input the noise appears again.

I want to read your opinion before I call LG service.

Thanks

hi im thinking of the 50pg7000 but confused as it states analogue tuner with freeview- does this mean i cannot use freesat?

you can use freesat, if you buy a seperate freesat box and dish.

Got one of these the other day and I think its a truly cracking set coming from a SAmsung 46 A656 - the samsung had a slightly more subtle dark look about the blacks but overall the LG manages more consistent black , i.e the blacks are really deep where they need to be,and not so when not neccessary.

Anyone got any idea why Film Mode is greyed on HD? Very annoying...

No way of turning it on somewhow and having it stay on (although greyed out)?

Motion is a lot smoother on here than the sammy but i do still get the odd judder on dvds and in particular Sky 1080i HD, wondering if that really is cheap as chips hdmi cables fault or whether its the sky box / plasma processing at fault?

I got this set at Christmas time. I encountered the tv changing channel upon bootup as in some other models. I got the software upgraded via the service engineer and this has solved the problem. New software is V03.22.00

Hi all,
Does anyone know where i can buy one of these plasmas?
Cant seem to find anyone who stocks it.
I've had conflicting reports saying its been discontinued, but Selfridges have 9 on order 7 pre sold?

Thanks.

LG uk support have nothing to do with your issue, and this isnt the LG support forum.
your consumer problems and complaints still lie between you, and LG portugal.
the best advice you can get is to contact,if you have one in portugal, a consumer advice office,or something similar to trading standards.
LG uk,will have nothing to do with the way LG operates in portugal,or any other country, and your problems will have to rectified closer to home.

Yesterday I was doing some testing with my laptop connected to my LG 50PG7000 and this was what I found.

As default the laptop choose 60Hz for the refresh and uses the maximum resolution of the display, in this case 1920x1080 but the colours seemed strange like if the laptop had 8 bit colour depth.
Tried 1360x768 and the colours are back to normal. After changing between resolutions only the "HD" 720p and 1080p had this issue.
But if I labelled the input(HDMI) to "PC" the colours are back to normal on all resolutions but only at 60Hz, the "PC" label as no impact on 50Hz and sadly at 24Hz too.
Configuring my BR to 60Hz and label that HDMI to "PC" improved the quality a lot.

Anyone with a laptop can confirm this?

That sounds like an issue with the amount of available memory in the graphics card on the laptop. At higher resolutions, if the graphics card doesn't have enough memory, it reduces the bit depth to save memory ... does the laptop happen to be a few years old?

Tried with two laptops, one is brand new with geforce 9650 1GB VRam and the other have a 8400G 256MB VRam.

Its not a memory issue because at 1920x1080x32bit/60Hz and HDMI with "PC" label the colours are fine. If I change the label (at the TV) to something else than "PC" I lose colour detail. At 1280x720 is the same.
The interesting thing here is that at any other resolution than 720p and 1080p the "PC" label has no effect and colours are fine.
At 24Hz and 50Hz and at any resolution the "PC" label has no effect on improving colours

.
I thing is some sort of posterization/colour banding.
And there is a difference on viewing a BR at 24Hz and 60Hz. I see much more detail at 60Hz than at 24Hz.
