These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/ http://electro-medical.blogspot.com/
Blinking codes details of many popular brand TVs are given. Surf the site with patience.
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,
"Plasma flat screen technology consists of hundreds of thousands of individual pixel cells, which allow electric pulses (stemming from electrodes) to excite rare natural gases-usually xenon and neon-causing them to glow and produce light. This light illuminates the proper balance of red, green, or blue phosphors contained in each cell to display the proper color sequence from the light. Each pixel cell is essentially an individual microscopic florescent light bulb, receiving instruction from software contained on the rear electrostatic silicon board. Look very closely at a plasma TV and you can actually see the individual pixel cell coloration of red, green, and blue bars. You can also see the black ribs which separate each."
If the line of pixels is on the edges of your TV screen, then it is usually related to the signal feed to the TV and not the fault of the TV.
You can see thissemi-common issue with some TV antenna, Cable, and Satellite signals fed to the TV.
This will also happen if you are running a signal from one device through another device and then to the TV.
Example: Blu-Ray signal goes to the A/V amp and then over to the TV.
If the line of pixels is well away from the edge of the screen and is constant for all inputs (HDMI, Component, AVI) then this issue is the fault of at least one of the image drive boards. To trouble shoot this issue would require some TV repair tools and some knowledge of electronics.
I hope this information has helped you.
