Green Vertical Lines on Sony 55" LCD TV Model - KLV 55X450A
Green Vertical Lines appear all over the screen along with the picture. Sound is normal.
Could we suspect the digital/logic board bearing number 1-877-350-11?
What is the function of this board and what are the complaints if this board is defective? What are the other alternative methods to resolve the above problem?
Incidentally all ribbon connectors have been checked and are found intact.
Es esta una buena pregunta?
