New HDTV, new cable box, bad picture |
|
|
I just got setup with a Samsung 56" DLP TV (HLR5667W), and whatever HDTV
cable box Time Warner Cable gave me (Cary, NC Area), hooked up with the
provided composite cables, and I'm not exactly thrilled with the picture.
On non-HD channels, it's a bit fuzzy, which I sort of expected (converting
regular TV to 720 lines of resolution isn't going to be clean...), but on
the HD channels, I see a lot of "blurring" around the action. Watching
football this weekend, it seemed the resolution in the areas of movement on
screen goes down - things get fuzzy or blurry. I haven't hooked the DVD
player up yet (will use HDMI for that) to see if the problem shows itself
there.
So I'm trying to figure out where the problem is. Since the TV has a native
resolution of 720 lines, I have the cable box outputting at 720p, which
cleared things up a bit from the 1080i (on the SD channels), but didn't do
much for this issue.
Here's what I'm thinking it could be:
Bad TV (defective)
Bad TV (design)
Bad cables from cable box to TV
Bad cable box
Bad signal in the cable
If the DVD player picture doesn't do this with the HDMI input, I will try
the DVI output from the cable box to the HDMI input on the TV, see what that
does, but I'm not hopeful at this point.
Anyone out there have any input? I'm kinda disappointed with the little
bang I've see for the bucks I've spent...
Thanks!

You better not have used a single composite coax cable......
This HDTV hookup has to be a component cable (3 coax) at the least....
DVI or HDMI would be better.... IF supported by the STB...
I hope TWCable used either a SA-3250-HD STB or SA-8300-HD box....
3100s or 8000s are not too good.....
TWCable signal strength into the STB should be +8db or higher!!
TWCable strength aft of STB (read by STB) should be +2db or better..

I doubt your problem is the TV set, either design or that specific set.
Assume you are connecting your box to the TV with component 3-cable set, not
actually composite. What you describe sounds like poor signal at some
point. Could be cable into your home, the box, from box to your set. Or at
the cable company.
I would call the cable company and have them come out and look at what you
are talking about. If you have a DVR box (I recommend the 8300HD, if they
have that), then record an example to your hard drive to show them. If not,
then, unless it does this pretty much all the time, you are going to have to
hope that the problem is something they are familiar with.

Do you have OTA capability? That would represent the best quality
check that you could make. |

1) is it hooked up to the componet inputs?
Any problems you have are going to be the cablebox not the TV. Digital
transmissions compress the video to conserve bandwidth. The compression
relys on large images of the same color for better compression. Fast moving
small objects can not be compressed as well. As a result they are the first
areas of the screen to show problems with the digital stream. This is
normal and in better set top boxes there are circuits to smooth these errors
out. It's not a tv problem but a problem with digital transmission
technology. There is no digital decompression going on in the tv with your
setup. The output of the cable box is analog video.

As others have said, it appears you mean component cables. |

I've noted that especially with 1080i sports broadcasts that there is |
some smearing and pixelation. I believe this is normal and also noted there is
a lot less of it with 720p. The CBS SEC Saturday football and NFL Sunday HD
broadcasts are 1080i. The ABC and Fox NFL HD broadcasts are 720p. NBC NASCAR
HD is 1080i. If you get smearing and pixelation on everything, then it could
be a problem with the signal quality from the cable co. and you should call
them and have them come out and try to improve it, if they can.
I don't get any cable only HD channels like ESPN and the movie channels, so I
can't comment on them.

SD is 480i, not 1080i. |

New/better cables, checking the attachments, a gold-plated cable wall plug,
and things look better. We're going to upgrade to a DVR box here shortly,
which requires TWC to send someone out, so I'll make sure he checks out the
signal strength coming in carefully.
Thanks for all the help!
