Red "rash" on plasma TV

When the TV signal (HD cable with set-top box) begins, or when DVD is played, there is a red "rash" across part of the screen. Although the "rash" is generally in the same are, it is not always the same size, and, sometimes, the "rash" is blue, or blue and red. Regardless, the "rash" is mainly noticeable in black areas. There is no "rash" b/f the cable box or DVD is turned on. Dying plasma? Hot pixels? Bad signal? TIA for any help. Mike Intermittenly, Red Pixels will flash on the screen, mostly center 1/3 of screen, in the black shaded area of the picture. Only with input from the cable box, not playing a DVD.

It's staying on 480i sd why not 1080i


There's only one way to get that TV to switch from 480i (which is an SD or Standard Definition signal) - that's to provide it with an ED or HD resolution signal (a 480P signal is often called ED or Enhanced Definition while 720P, 1080i and 1080P signals are called HD or High Definition).

The old standard yellow composite video cable.
.
You will not get ED or HD signals through the old composite RCA phono jacks (usually yellow in color), either. You'll need to use an RGB (red, green and blue) component video cable, HDMI cable, DVI, or other type supported by both your TV and the video source (CATV box, Blu Ray disc player, Satellite converter, etc.). More on this, later.

RGB cable.

steve_con_16.jpg
An HDMI cable - this provides Digital audio signals, too.
.
steve_con_17.jpg
A DVI cable.
.
First, you'll need a source capable of sending ED or HD signals. This can be a progressive scan DVD, Blu Ray player, HD Cable or Satellite converter, or a simple TV antenna. Not all DVD players are capable of the 480P progressive scan output - it must be labeled as such. The DVD movies are not labeled progressive scan as they all will play back at 480P if played in a DVD player capable of progressive scan, otherwise they play at 480i. A stand alone Blu Ray player or one in the Sony PlayStation 3, the older HD-DVD in the Xbox360, (it is important to note that the Nintendo Wii can output either 480i or 480P signals only when connected with their special component video cable), "set top boxes provided when you choose HD service from your local cable provider or satellite TV provider are the main sources for signals better than 480i. As mentioned above, the old standard yellow video jack is not capable of supporting signals better than 480i. You must use the HD jacks and cables between to get these signals into your TV.
steve_con_18.jpg
The Wii 480P cable assembly - includes stereo audio, too.


Lastly, if your TV has an ATSC tuner (it is not uncommon for it to have an NTSC tuner and CATV tuners as well), you can input a UHF antenna directly into the the antenna terminals on the TV. Broadcasters in most areas have been moved into UHF bands - but some areas have one or two that operate in the VHF bands still. Check antenna web for information and help selecting antennas and broadcasters in your area. The nice thing about the antenna method is that no other cables, converter boxes, etc are needed to enjoy HD signals - plus - they're free!

Just remember you need a source capable of ED or HD signals and a way to get those signals to your TV. The yellow composite cable is from days ago and only passes 480i signals.

I hope this helps and good luck! Please take a moment to rate my reply - thanks!

If by regular cables you are talking about the standard red/yellow/white composite cables, then, yes, it will affect HD as composite cannot send an HD signal. Only HDMI and component (red/blue/green video only) cables.

Change to HDMI and let us know if it works for you.

you may have to set the input value on the bravia for optical on the input from the cable box. sometimes there is more than one way for a particular input to receive an audio signal, you may have rca(red and white), a black or orange rca type for digital, and then the optical. i would suspect you have to tell the bravia how the sound is inputed into the bravia. also , just a thought.... on the cable box there should be a volume control on the front of the box........ make sure the cable box volume is ALL the way up (it is the preamp volume).

LG plasma buzzing


Problem is probably with your cable box as you have confirmed that the set is working by using the dvd player, that is unless you have a bad cable for the cable box.

anytime you connect componet signal (green red and blue)to regular video inputs (yellow) end will have same effect. make sure that if you are using component signal from source(cable box,dvd player etc) you have to connected to component input in the set.
component signal will use green red and blue for video and red and white for sound.

Too much green color


Problem solved. I tried playing DVD and the TV picture was fine. So I double-checked cable wires from cable box - one of the wires was loose (obviously it was the red color input). After tightening, the TV picture is good as new.

The picture has shrunk - maybe 720P vs 480P?


make sure your hd cable connection from your cable box is going to an hd connection to your tv.[via hdmi, dvi,or componant.] if you have a different hook up such as rca out or coax out, these are not hd connections and you are probably streching out the picture.look at the rear of the tv & cable box and see how the connections are.the hd hook up to the hd input should make the picture the right size only if it's set on the hd input channel.hook up the dvd player to a aux/line in or video/source input and try changing the picture size. you may have to play around with it till you get it the way you want.
hope this helps.

Why are you running hdmi to converter box? Run HDMI cable directly from dvd to new Panasonic plasma. The less things in between, the better the picture.
