My sony wega 3lcd tv seems to have long dust lines inside the tv screen, what is it and do I get rid of it


Dust lines? Please explain. Are they single pixle lines on the screen itself? These are the signs of a failing display.

Picture is dark


Adjust video settings:
  1. Press Wega Gate
  2. Select Settings
  3. Highlight Video
  4. Press + to select
  5. Adjust/increase the brightness.
  6. Press Wega gate to exit.
If picture is still dark, you need to replace the lamp again. Sony recommends that you replace the lamp:
  1. After approximately 8,000 hours of use.
  2. When the screen becomes dark or the color becomes unusual.
  3. When the lamp indicator on the front of the TV flashes.

I have a 2.5 year old kdf-e55a20 grand wega. Screen goes dark, no audio, comes back after a minute or less, stays on for short time or could stay on for hours.


Hi!

Sounds like your signal tuner or your main board (main unit), if the 2 boards are separate I would say your signal board. But you may also look at your power supply for any bad caps (capacitors), they would be bulging on the top or leaky (brownish stain) if they were bad. This drives all the boards that above mention!
