problem: LCD monitor with backgroung image delay...??
 

I am having a problem that I have only noticed recently.
I have a Sharp LC32GA8E connected mainly to a freeview box (digital TV
- UK), nearly 1 year old.
Sometime it happens that, on some scenes, there are parts of the image/
video that are not moving along to the rest of the image/video.

To make an example I have noticed that "sometime" the face of an actor
is not moving all together, it is like the skin stay still or moves
with a delay. Sometime it happens to the background too.
Usually it happens when there is a scene where the camera is shaking a
bit.
The problem doesn't show all the time, it seems to me that it happens
when some components get too hot so they don't process the image like
they should... or maybe I should shut up because I don't know anything
about it ;-)

I called Sharp technical support and they came twice to fix the
problem.
The first time they replaced the main unit where the cpu is: I thought
it was a video problem so I was expecting the AV card to be replaced.
Anyway, nothing changed and they said that usually they don't replace
the AV card because most of the time is the mainboard to be blamed.
The second time, the engineer didn't replace anything, just played
with some settings which made the problem even worse... I let him go
because he was really useless.

Does anyone experienced the same problem? How can be solved?
Should I call Sharp again before the warranty expire?
Thanks for any info....

If this only happens with the freeview box, I would suspect that, rather
than the TV. If you are using HDMI, try component.

This sounds more like an artifact of digital over compression, than a flaw
of the TV. In static scenes, like backgrounds that dont move, the refresh
rate drops. When the scene does move, it takes a second for the picture to
catch up. I've noticed the same exact effect from the newscasts on the
Superstations from satellite. They are highly compressed, and since nothing
in the picture is moving except the news announcers mouth, the refresh rate
drops to a point where the only movement you see is a jerky, "freeze-frame"
effect. I doubt your TV is at fault.
I would respectfully suggest that you do some research on the flaws of
digital over compression, both on cable and satellite.

I have that problem occasionally but due to weather. I have a VIZIO on a
porch where there are a lot of trees. That TV has only a small loop antenna
for OTA reception and generally it works fine. On windy days I'll get a
breakup as you describe but as I understand, The ATSC protocol only updates
that part of the image that is changed from the previous update. So on a
program such as the news where most of the image is a speakers face I'll see
the breakup around the mouth but due to dropped packets.

He is in England, so it is not ATSC, but same idea. I still think

Number 1 suspect is antenna
Number 2 suspect is Freeview box , especially if it varies with temperature.

More than likely this is exactly what the problem is. I encountered
this problem consistently on certain channels back when I had DiSH
(but have since moved back to cable and have never seen the problem -
on the same HDTVs).

Its an artifact of digital, not analog channels. And the TV has nothing to
do with it.

Umm, yeah, I was agreeing with everything you previously posted :) -
specifically, it's over-compression artifacts

OK, thanks. I was just saying that any channel on
satellite, which would be digital, might exhibit those symptoms, while the
same channel on cable, which may be analog, would not show those symptoms:)

Hi again,
sorry if I didn't reply earlier and thanks for all this info.
To reply some messages above, I had the same symptoms with DVDs as
well.... but on a cheap player, don't know if this matter.
Now I bought a sligthly better one and connected with a HDMI cable.
I haven't had the chance to test it because after few days I had to go
abroad, so in a couple of weeks I will and let you know.
thanks again.
