The connection from the drive PCB to the actual glass part is probably 
by way of a flexible strip that looks like rubber, but has alternating 
conductive & insulating sections. Over time, this can become fatigued & 
fail to keep its  shape. I had a very similar problem on an old Nokia 
9000 communicator, which I solved by dismantling it far enough to access 
the strip, kneading the strip gently & reassembling the unit. They're a 
swine to get back together without the right jig, though.

*But* it didn't work anyway & was beyond economic repair, so I had 
nothing to lose....

The phone still works perfectly a couple of years later :-)

I've not tried this, but I've heard reports that on some occasions it 
and other similar programs can make things worse. You pays your money & 
takes your chances...
