The speckling is caused by the CTRL board. The firmware needs to be updated. Unfortunately LG does not provide a media slot for downloaded upgrades. You must order an install the factory updated CTRL board located between the power and the Y sustain boards.

Hi Mikshanks,

I had the same problem with my TV. It was a horizontal problem with different shades of color, and black spots. I replaced my Upper & Lower Y-buffer boards. Your Y-sus board should be okay since it still powers on the screen. You should replace the Y-buffers Upper & Lower, and it should work. I hope this helps.

best regards,

Colorful "speckles" on screen

Could be the screen burn from watching T.V. on a show and the thing burnt in (in this case the colors, yes it can burn colors.) and there's nothing you can do. The insides of the T.V.'s have plasma gases which can flow out of control.

I get a red/blue/green static at the top of my plasma tv.. when the picture goes to a dark color its usually speckles red.. then when its a light color it doesnt really show.. wats the problem?

In some cases it is just a matter of making voltage adjustments on a plasma set to get rid of the spots you are seeing. I would look for a reputable technician in your area to see if this is the case. Good luck...

First of all, is your blue "HD" light lit up on the front of your Uverse box?

If yes, then you're in HD

If No, you need to check your connections from Box to TV
1.Those Red-Blue-Green cables are for video only, they don't carry sound and shouldn't be connected to audio outs. Audio needs a seperate cable. Make sure your Red isn't on the audio out which is also red. Make sure your blue and green aren't switched with each other either. Check that at both ends.
2. Try an HDMI cable. It will carry audio and video together and it's one cord instead of 5.
3. What brand/model of TV is it? Is it an older projection TV? The HD tuner might be shot. The individual color tubes commonly fail after a few years.
4. Are you selecting 720p or 1080i from your TV's menu or from the Uverse menu? You'll need to set it through the Uverse box, not the TV.
5.Follow -Menu -Settings -Aspect Ratio to change to 720 or 1080. This should start an autotest which will scramble your picture for about 5 seconds, then bring you back to a menu asking you to keep settings or revert back settings. If you never see that question pop up, then your TV isn't supporting the HD, and you settings will be rolled back automatically. If the question does pop up and you can read it, select "keep settings" and press OK. Your blue HD light should come on the front of the box now.

3 green spots on the top center of my projection hd tv

I had a similar problem and brought it in to a technician for a quote of $860 to fix. The problem - speck of dust on the optics. If it weren't under warranty I would take it apart and blow off the dust myself.
