Msi L1350d screen has tiny horizontal lines


If it works fine when you connect to your tv then you've probably got a loose cable on the screen. You'll have to strip it to check.

Vertical black bar on my LG 47" LCD shifting the image to the right


Two possibilities are there. The first one is, with loose LVDS cable, that connects the T'Con board to display panel. The second is the fault with its main digital processor board.

When I turn on my nuvi 200 it says press dot. When I press the dot it just moves around the screen to different location.


To calibrate the touchscreen on your nuvi 200 series follow the steps below:
  1. Have the unit turned OFF and unplugged from power.
  2. Slide the power switch to the ON position and hold for about 45 seconds.
  3. A message will display on the screen: Press Dot.
  4. Once this message displays, release the Power button.
  5. Press in the center of the Dot.
  6. Keep pressing in the center of the Dot as it moves around the screen.
  7. Once this is complete, there will be a message: Calibration Complete.
  8. Touch Ok and the unit will restart.
The touchscreen will now be recalibrated.
*Note if unit is running software version 6.00 or newer you will want to follow steps from below.

To calibrate the touchscreen on your nuvi 205 series follow the steps below:

I have dots all over my screen. How can I remove the dots?


Try unplugging the TV and leaving it unplugged for 30 minutes..

Then try plugging it back in.. If the dots dont dissapear.

Try shutting it off.. and removing all input cords.. Are the dots still there with no input going into it..?

If not, then the issue is with one of your cords or input devices ( cable box, dvd player , etc)

If the dots are there without anything plugged in. Its an issue with the Tv itself, and will need to be serviced

What is subfield ? panasonic says subfiels what is subfield ?


Does this help
A standard video signal is actually a series of still images, flashed on screen so quickly that we believe we are watching a moving image. The typical frame rate used in North America is 60 frames per second (60Hz) meaning that a TV would display 60 individual still images every second. Sub-field drive is the method used to flash the individual image elements (dots) on a plasma panel. For each frame displayed on the TV the Sub-field drive flashes the dots 8 times or more, meaning that the dots are flashing 480 times per second (480Hz) or more. (Example: 60 frames per second x 8 sub-fields = 480 flashes per second). subfielddrive_en.jpg
