LCD Inverter Connection

#1 Post by sausage888 » Mon Aug 24, 2009 9:28 pm

This is more of a comment than a question, but replies welcome.

I have now replaced two burnt out LCDs in two different A31x laptops. In both cases, after installing the new LCDs, the laptop screens were nice and bright. In both cases, I eventually had trouble with the new LCDs blacking out again after putting the computers into stand-by mode (closing the lid), then waking them up.

After awhile I get tired of dismantling the delicate bezel and re-seating the inverter card, only to have it lose connection again after another number of lid closings. My solution has been to neatly wad up a tiny amount of matchbook cardboard glued under the bezel directly over the place where the inverter connects to the LCD ribbon cable. It seems that after I do this, it applies just enough pressure that the LCD never blacks out again.

Wonder why I can never get the inverter to re-seat successfully for the long haul? It seems "seated" when I do it, then it eventually must pop off from the ribbon cable stretching due to the lid being opened then closed.
