Question about Gateway LCD30TV Television

1 Answer

Diagonal lines moving from bottom to top

I've had a good picture for 3 years and suddenly when I turn on the tv for the first time in the morning, there will be diagonal lines moving from bottom to top in varying width (from 1/8 " to 1/2"). The picture is not distorted while this is going on. The first few days, it cleared up after about 15 minutes. Today, it took almost 25 minutes to clear up. And right now, after being on for several hours, the lines are constant. Will this be expensive to fix.

I have evenly spaced, rows of two vertical green and red lines from top to bottom of my vizio plasma P50HDTV10A

Somehow when switching between the tv and the dvd my wife encountered the pink and green, thin, parallel, vertical lines on the screen. The picture was visible with the lines. I turned the tv off and on but the problem persisted. Unplugged tv for about two minutes and after plugging it back in and turning it on the vertical lines very gone and the picture was back to normal.

Horizantal lines while showing the picture

In most cases on a plama TV the upper and lower buffer boards will cause diagonal lines to appear in the picture in top or bottom half or sometimes both.

Diagonal lines on upper 1/3 of screen

It sounds like the dmd board may be defective but you can try rebooting the set and see if it makes the picture any better...
1 - Turn on the Tv.
2 - Press & Hold the up arrow key on the remote and then press the power button on the front of the Tv.
3 - Tv will reset & reboot

If the picture is the same it's probably the dmd board which is part of the "B" block assembly and I don't believe they're sold separately. The "B" block is about $1100.00 dollars.
Hope this helps!

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.

If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.

Moving line through plasma and LCD TV's

This is a very common Ground loop problem. The quick cure is to put a 2 prong to 3 prong adapter on the plugs which effectivly removes the ground from the circuit and stops your lines. Have fixed over a hundred TV's since the 60's that way.
