Hi,

I have often replaced backlights in LCD's. Occasionally, like just now,

I
get one which no matter what I try, I can't get all the pixels to

reconnect.
It's the business of that squidgy rubber contact strip that connects

between
the PCB and the LCD glass and is held in place by the metal cover of the
LCD, where you twist the lugs that protude through the PCB to secure it.

I
always try and leave the LCD intact, but occasionally, as in this case,

the
backlight will not come out without dismantling it.

I don't think I have damaged anything, and I have cleaned all the

relevant
contacts and the strip with alcohol and switch cleaner but there are

still 2
vertical bars unconnecting. Pressing really hard on the LCD housing

will
not light them. Does anyone have any general hints and tips for these?


Have you tried turning the "zebra stripe" rubber strips around to see if
the dead areas move?
