Re: Can anyone detail LCD connections for me LCD repair

I ahve purchased an Inspiron laptop on emaby and after 30 dyas its
starting to sow intermitent horizontal lines on the screen. These lines
look different each time and move around. They usually start when I
pick up and move the lap top. They can sometmes be "cured" by moving
the LCD screen back and forth, sometimes by pressing on the laptop area
above the heyboard, and sometimes they just go away.

But they come back.

I can run a monitor of the external video with no problems while the
horizontal lines are there.

The LCD screen stays bright all the time.

From this I conclude. 

There is nothing intrinsicly worng with the video on the laptop.
There is nothing wrong with the invertor.


There is a faulty connection somewhere either on the CPU board
the ribbon cable is bad
on the LCD board

Can someone clearly detail for me all the possible points of failure
and the liklihood of repair in each case.

I have no problem opening the case and replacin parts. I have replaced
ribbin cables before but I am concerned that it might be something more
serious like the conector connections on the logic board etc.

Any help appreciated

It's unlikely that there's anything that you can fix.
IF the display cable goes, it likely takes the whole display out...or at least a range of colors depending on the interface details.
For a few intermittent horizontal lines, it's probably the connection between the display drivers and the glass. You can't fix that.
Sometimes, depending on how it's constructed, you can put in some foam
to push the conductors where they contact the glass, but I haven't
seen one where they're accessible in a long time.
