Why does my new HDTX pixelate so damn much on cable systeM?
 
JUST received my new Panasonic 32" 1080p TV from New
Egg

Connected up to my cable system and it pixelates!!

WTF!!!

I'm not very happy

What's going on? I checked all connections and they
are tight.

You sure it's not the cable system? They drop packets
all the time. If you have a DVD burner hooked up,
record the program to it, then play it back on your computer.
If it's a far end problem, the pixellation will show up
on your computer, too.

Many questions.
1: is this your only digital TV on cable?
2: Are you using a cable box?
3: Do you have another cable box to try?
4: If you have a second digital set, does _it_ work properly?
5: Can you try the second set (if available) on the same cable the new
set workd bad with?
6: I presume you have more that 1 set even if it's analog. Have you
tried the new set on another cable feed?
7: You likely have analog channels on your set. How do they look?
Noisy?
8: ?????????

Need more info to help.

Most MSO's recompress HD channels.

The recompression would show up as less detail in the picture or
macroblocking on fast motion scenes, not breaking up with pixelation.
The OP problem is likely due to poor signal level caused by weak signal
levels reaching his house or problems in his internal cable. Since he is
paying the cable company for the service, he needs to call the cable
company for a service call (however much of a pain that may be).

Yes it could be them

But I didn't get the TV till Friday night so couldn't
call them

No second set but will move this TV to another feed and
try it there

That's what I'm thinking as well

I have an outdoor antenna I could use and just drop the
cable..... but not sure I can mount it outside anywhere

But what I was describing was how I would debug such a thing.
You have to know whether the data loss is coming from the cable company
or from the set.

It may be possible that the thing is good enough that the
pixellation has been there all along, and you just couldn't
see it.

I have *no exposure whatsoever* to these, but there are
"powered rabbit ears" antenna units that carry HDTV
frequencies. Might work; depends on signal strength.

Understood

But I just moved to this apartment not very long ago
from another town.... and have not had ANY TV at all
for some months... not even analog. I sold everything
before moving cause didn't want to haul it this far.

At any rate.... I just hooked it up to another cable
feed and its still pixellating . Not so bad you cant
watch anything..... but just enough to be annoying.

I will try another piece of coax and see what
happens.... but my gut feeling is that it IZS the cable
system itself.

Or.... could hook it up to antenna and just lay the
antenna high on the shelves and see what happens

OK

I have good outdoor antenna that I kept before
moving..... but in this new place don't know of a good
place to mount it outside

At any rate...... I surely DO appreciate everyone's
help! This is my first foray into owning an HDTV

Frankly I'm abt ready to just use it as a big monitor
to watch TV of the Internet!

Don't waste your money on powered rabbit ears or any other powered
antenna intended to be used close to the TV. An amplifier can't
improve the signal from the antenna, it can only preserve it from
further degradation on its way to the TV. With a short cable that
degradation is negligible. Also, a strong local signal on any channel
can overload the amp, making it impossible to receive anything on any
channel.

Try to receive at least one channel with an antenna and compare it
with the same thing from cable to see if your cable service is the
problem. First, plug your location into www.tvfool.com to see if you
have a chance to get OTA channels, what channels they are and in what
direction(s). Remember that the channels they actually transmit on
are usually not the same as the virtual channels reported by your TV.

If the antenna you have is small enough to set up indoors for test
purposes, use that. Otherwise buy or borrow a cheap, non-powered
rabbit ears (for VHF) and/or loop (for UHF). Put a long enough cable
on it to move it around your apartment looking for a sweet spot. Once
you know what's available you can decide if it's worth getting a
better antenna or if you're stuck with cable.

Pixelation on fast movement or scene changes is likely due to
overcompression. Pixelation unrelated to what's happening in the
picture suggests a marginal lock due to low signal, although there can
be other causes.

Yes... THAT seems to be what's happening!

When picture is of something stationary...... no
pixelation

You have bad connectors or the wrong cable or missmatched cables.
The connectors must be clean (with clean cuts on the wire and with
the right length of wire so that rubbing contact is made).

Make sure your ground point is good too.

Remove all connectors; look inside for any debris; and reconnect.

OK

Maybe I will just go buy a new piece of coax, yes?

Why on earth would you put this into a new unit? It probably costs
more than the new coax. I could probably use some de-oxit on the Ampex
AVR-1 I'm working on at work but that machine was built in 1972 so it
has an excuse.

Oh, he's in an apartment. Oh, well.

Rotsa ruck trying to clean/fix any of those other corroded connections.

"reseating" properly built connectors are Supposed to provide sufficient
sliding action to clean the contacts.

And if they are not to spec... well, it's a crapshoot.
