I have a un75es9000f and the picture looks plaid I had some movers move it and after we hung it and turned it on it looks plaid and has a bubble on the bottom of screen any ideas of the problem


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Green Plaid lines on Samsung HLR5067wax/xaa-


These are the Tests that should be run to determine which board is bad.You should call a good TV Tech if you are not familiar with this TV.
- The DDP1011 on the DMD board has a feature to display internal test patterns.
- DNle, which is an end port in the digital board, has a feature to display internal test patterns.
- The analog board sends signals to ADV7402 on the digital board.
- The analog board is the first output and the digital board is the second one, followed by DMD, which is the final one.
■ Diagnosis By Module
1. Access Service Mode
(In Standby mode, press "Mute", "1", "8", "2" and "Power" to turn the screen on and enter service mode)
2. Check if there is an error in the DMD board
DDP1011 → TEST PATTERN → Press the right arrow key:
Options of FULL WHITE, BLACK, RED, GREEN and BLUE PATTERN are displayed on the screen.
If "Pattern" does not appear, this is a DMD board error.
3. Check if there is an error in the digital board before the DMD.
When the DMD board has been determined to be error free based on the test patterns:
FACTORY MODE → DNIe → TEST PATTERN normal display: no error in the digital board.
If "Pattern" does not appear, it may be from a DMD board or ATI error or there is an analog board malfunction.
4. Check if there is an error in the analog board.
Check for a power signal from the analog to the digital boards

The picture on my LTV-19w3 WH tv just shows a blue, black, or green screen with about a 4" sq. plaid patch in the upper right hand corner. Sometimes the sounds works other times it does not. Can anyone...


While the TV is on do the following:

1. Press the "Right Arrow" button on the remote.
2. Press the "Left Arrow" button on the remote
3. press the number keys in order, 1-9

I believe you are in the TV's service menu and the Blue/Green/Black are just test patters. If so, pressing these keys will eventually change the pattern..

Get to the main page of the service menu and press the [power] button on the remote.

Ripples appear in the image when photographing an object with fine plaids or stripes. How can I fix that?


When you are shooting a subject that has a fine regular pattern such as stripes or plaids, a ripple that does not exist on the subject sometimes appears in the image. An example of this can be seen in the pictures below. The photo on the left shows the fine plaids pattern on the shirt. The photo on the right is a distance shot of the same shirt. In this photo, you can see a ripple that is not visible in the photo on the left. This effect is called the Moire effect. Why does the Moire effect occur? Digital cameras and camcorders are equipped with imaging devices such as CCD sensors and CMOS sensors that have pixels that are finely aligned horizontally and vertically that convert light into electronic signals. When the pixels and the pattern on the subject overlap slightly misaligned, an interference pattern occurs and a ripple that does not exist on the actual subject may appear. This is the Moire effect. Look at the image above. This image shows red cross-stripes and black cross-stripes overlapped slightly misaligned. When you look at the entire image, you find a ripple that differs from either of the patterns. This is the same principle that causes the Moire effect. Preventing the Moire effect You can reduce this effect by changing the distance, zoom setting or the angle of the image. If you are using a camera with manual focusing, the Moire effect can be reduced by simply changing the focus slightly. Reference You may find another Moire effect displayed on the LCD of the camera. As this is caused by the aligned pixels on the LCD, this effect does not necessarily appear in pictures you have taken.
