Anyone knows where white spots on the screen along the bottom of the tv screen can be coming from


The spots are part of the transmitted signal. Normally they are masked so you don't see them.

White spot on screen


Sounds like you are describing stuck/dead pixel.

There is no fix, it is a Pixel gone out in display panel, good chance it is just stuck and will right itself but sadly sometimes they dont and the only fix is to replace the entire display panel
Manufactures warrant such defects different depending on amount of dead pixels on screen is considered faulty, ie 3 pixels grouped or 5 separate ones .

MY SHARP AQUOS 70" tv STARTED HAVING DARK SHADOWS ACROS 1/2 OF THE SCREEN, THE OTHER HALF OF THE SCREEN IS FINE. DO I HAVE A hdmi INPUT PROBLEM OR IS THERE A TV DEFECT?


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.

Vertical lines of stuck pixels


If a LCD TV has vertical or horizontal lines, in most of the case the problem is a defective LCD panel.

GREY SPOTS ON BACK OF SCREEN NOTICEABLE WITH WHITE


Hi if your tv is a dlp it might be an issue with the DMD board Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!
