Hi Eddie

OK if you press the menu button of the sets own remote control are the lines over the menu display please?

Customer: replied 3 years ago.

Yes the lines are over the menu display..I am using the menu button on the TV though as my customer has lost their remote..If we do repair it I will get them one. You did see where the green LED flashes on the Main Logic CTRL board?

Customer: replied 3 years ago.

Please note...Disregard the trouble where you can only go between PC and Rf..This Tv requires you have something hooked up to the input to change between sources


OK the vertical lines are they grouped together or coming across the set ?how thick are they?

from left to right 1st one is 6" in then the next 0ne is 14" from that and the next 3 are 3" apart then 14" from there is the last one that is 6" from right..they arePencil line thin except the center one is 3 pencil lines as is the far right one..

Hi Eddie
