Is it true that when one pixel goes out, others are soon to follow?


No, that's not true at all. Each pixel is its only little device - one pixel does not effect another. The pixels work together to make a picture, but are all controlled separately. If your pixel is "stuck" and not dead, then you may be able to fix it! A stuck pixel is red, blue, green or white, while a dead pixel will show up as black. Sometimes a stuck pixel can be fixed by covering a pencil eraser with a cloth and pushing down on the pixel gently while the TV is on. So, in summary - no, one bad pixel doesn't mean any other pixels are bad. Hope that helps, Alex

It depends on the size,location and how many dead pixels. If remember less that 5 they won't do nothing about them. Call the warranty people and find out. they will for the location, size of pixel and quantities. Good luck to you.

You wont want to hear this.....

Green dots on a LCD screen are burnt out pixels and unfortunately are incurable other than having the TV serviced at a high price. One of the reasons it is a good idea to get a warranty on these types of TVs is primarily due to this very problem....burnt out pixels.

A fine green vertical line displayed on the Sony Bravia 46.


Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

You need to adjust the panel voltages, adjust the VS voltage to around 186 volts, if that doesn't change it then adjust the V-Scan voltage down, turn the unit on and apply a video source to it, and while adjusting the voltages look at the screen and you should be abe to watch the video noise fade out.
