LG 42 inch Plasma TV - faults - no raster - discharge - bars or lines
There are several positive characteristics presented by a plasma TV, such as:
Possibility to build screens with large visual areas, and the most popular size today is 42-inch, reaching more than 100 inches, LG in Korea has the 102-inch model. In Brazil podese find purchase MW71PY10 model of 71 inches. Compared to other products such as CRT TV or LCD, plasma TV is leading to greater advantage when thinking about screen size. There is also television sets projection that can display screens of 60 inches, but lose brightness as the size increases screen, which does not occur with plasma televisions. The most common technology for projection televisions today are; kinescope, LCD, DLP and LCoS.
Very low thicknesses. Although not a unique characteristic of the plasma
televisions, when combined with the characteristic of having large
screens, plasma TV is extremely attractive, since it allows installation
in walls such that an artistic picture. The space used by products
today is highly valued, and compared to kinescope televisions plasma
reaches easily have a tenth of the thickness of a conventional TV.
Weight proportionally smaller. Comparing the kinescope larger televisions with plasma which is lower persebe how a plasma TV is lighter than a conventional CRT. A 38-inch TV can reach have more than 100 kg, as a 42 inch plasma has around 40 kg
- Screen Uniformity. For plasma televisions there is no beam deflection, resulting in an image very more uniform without linearity problems. A digital image consists of millions of points which are the picture elements known as pixels, while view this image we see in reality thousands of small luninosos points that together make the effect of image.
Does not suffer influence magnetic field. There around our planet a
natural magnetic field, the same as guides compasses, which can cause
minimum variations in kinescope TVs, the Earth's magnetic field
interacts with the field of deflection yokes of conventional TVs causing
small deformations, as well as any another magnetic field, be it from
speakers or any other source, can cause major distortions or effects
that cause spots on the kinescope screen. In plasma TVs each point
individually lights.

Appears after-image as shadow.
It occurs in the old module.
Can solve with adjustment voltage VS. (+ / - 3~5V)
Defect:
Discharge
If
you cannot adjust VS voltage switch
YSUS
Board.
Checkpoint: Check VSC Board
Defect : Discharge defect in any specific color
Change VSC Board.
Appears
on the screen bars: Module Control Board
Checkpoint:
Check the version of Micon and Control Board
Default:
With certain range appear the bars (OSD works normally)
Solution:
Switch Module Control Board.
