[mzone]

42" MZ-42PZ44 Plasma Screen lg plasma .

it origanally had 2 black vertical lines on picture.

picture below



managed to repair the black lines there was a dry joint on 10Ω register (4) in front of COF IC the black bars have now  now gone but instead theres now faint white lines on picture, there was tiny resistors next to the 10Ω registers ( 4 ) which i did not touch so not sure if one of the smaller ones ( 4 of them ) would cause this white line problem?

or if its screen burn or image retention?

heres 2 pictures of the set now with the white bars.




picture when on white wash setting




the white lines are more prominent when pictures on a light background.

bigger pictures attached below.


anyone advize ?

thanks
