Green lines all over the screen denotes tow faults. The first one is with its T'Con board, and the other is with its display panel. It is best to contact any service technician, to make a confirmation.google.com/+GopakumarGopalan

SOURCE: sharp aquos lines threw the picture

I've seen this problem before and if caught early (usually only a few pixels), its fixable. But if it has already started forming a "line" it might be too late and you might have a defective LCD panel. Most of the time, doing the factory initialization helps with this problem.

(WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)

  1. unplug tv
  2. press and hold at the same time “Vol –“ and “input” button on the TV set.
  3. while holding those buttons, plug the tv back in
  4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go
  5. then at the same time press “Vol –“ and “Ch. Down”, you should see the service menu appear (if it does not appear, try pressing the two buttons again, it needs to be exactly at the same time)
  6. Then use the “Ch. Down” button to navigate down the service menu until you see “Industry Init” (NOT Industry Init +cause)
  7. Then press “Vol +” to toggle it to “ON”
  8. Then “/////////////////” should appear.
  9. when the screen turns GREEN, unplug the TV. Wait about 30 seconds, then plug the TV back in.
  10. Then continue on with the initial setup again.

SOURCE: Horizontal green line appears on screen

my maxent plasma tv has the same problem but it has green and red lines. I found out that hitting the tv from the back works. It used to last a long time but now i have to get up now and then to slap the tv on back with my hands! anyone with a long term solution?

SOURCE: green vertical line on the right side of screen

Warranty still alive?
Hope so; the problem could be an expensive one.

The screen appearance is controlled by allowing light from a backlight through by turning pixels off and on.
This switching is done by a matrix that turns on vertical and horizontal pixels of the right shade at the right time to produce the image you see.
One of the control elements for the vertical that controls the transmission of green light from the backlight, has died (no longer switching off and on when told) and these are normally a part of the LCD screen assembly itself and not easily replaceable.

I would be talking to Sharp - this shouldn't happen in 6-7 months of use.

you will find 4 screws at the back of the tv about 4" inches from the bottom. lay the tv set flat on your bed. you will need a metric allen wrench to remove the 4 screw. once the 4 screws are removed slide the base away from the tv.

Horizontal lines showing behind tv menu


Hello,
Normally the menu is generated in the LCD Control Unit. If your menu looks good, but the defect is behind the menu, I would suspect the Main PCB. Good luck to you. Part# is DUNTKD934FM01-V1.

Screen damaged from fall, colored vert lines on left side from the damge


Unfortunately the LCD panel would need to be replaced. Even if there is not any signs of damage to the outside portion of the panel, one of the inner screens may have been fractured. I am not sure if the panel would be available because if i'm not mistaken Sharp just started making replacement panels.

Sharp aquos hdtv has sound but shows a white screen


yes and no. That particular tv you have is done for, but if you just purchased it 6 months ago, you are still within you 1 year warranty with sharp. they will ask you to take it to a authorized service center and you need to follow through with the process. about a week or 2 will pass and the service center will deem the unit unrepairable and sharp will replace it if they cant solve the problem. give em call..good luck 2u

What kind of connections are you using?

If component (red, green, blue) double check to make sure they are seated properly. I'm thinking it sounds like the blue one got loose.
