Answers :

I have a PCV-W20 and I had the issues with the flickering screen and\015\012blackouts. After reading a few postings i discovered the issue was a\015\012faulty CCFL. There are two in this unit. I did not know that when I\015\012ordered just one. When it arrived I had already taken the unit apart\015\012and was ready to replace the lamp. After soldering the connections the\015\012figuring out how to put the unit back together, it worked! After\015\012replacing the CCFL lamp the unit does not experience blackouts.

Like\015\012I mentioned this unit has two CCFL lamps. When I pulled it out I\015\012noticed one was a little darker than the other. I figured this was the\015\012one that was bad, and luckily it was.

I do have a line running\015\012across the screen now which I have not been able to figure out. Maybe\015\012it has something to do with the light escaping from the side. I'm not\015\012sure.
Does it flicker if you move the screen back and forth?
\015\012
\015\012If so then you probably have a bad connection between the screen and the system, you would need to replace the video cable going from the screen to the system board.
\015\012
\015\012Is there a little button above the keyboard that the screen would depress when it is closed? If so try pressing that button a few times to see if the screen comes on.
\015\012Or do you see a faint picture is you look REALLY!!! close to the screen?
\015\012
\015\012If so the inverter board is faulty and would need to be replaced.
