Well I managed to drop my Beo4 onto a stone surface and the LCD screen cracked.  Quick visit to eBay and a new one arived in the post.

I opened it up (there's a secret screw hidden in the battery component under the barcode sticker).  But then I found that the old screen has a shiny back whereas this one has a dull, white look.  It said on a piece of paper that came with the LCD not to touch this or the contacts (to keep oils/sweat off obviously).  However, I don't know wether there is a whitish backing and a new metalic finish to the rear of the newer LCDs or whether this is a film or backing that I need to peel off, presumably by using a thin screendriver or scalpel.

Anyone else done this to know?

Hope you didn't pay too much on eBay, the last one cost me 12 euros at the dealer...

But no, you are not supposed to peel anything off. The backing material probably just looks different - it's job is to reflect light at the front, it doesn't matter how it looks at the back.

Thanks, good to know that's not the touch sensitive bit then.

£12 plus postage, still cheaper than buying a new remote and it's probably a good price to pay for learning a leason about not dropping it onto stone again.

Voila it works.

Out of curiosity, does anyone know how the panel works? There's no electrical connection that I can see.

Well done! I think this might be worth a picture thread or a Wiki page... although at least some dealers are happy to replace the display while you wait, a lot of people need or want to do it themselves.

The electrical connection is through a small rubber strip on the side of the display that presses against the circuit board. It has conductive stripes that go through the rubber vertically, the other end presses against the front glass of the LCD, where they meet the very thin layers of metal that work as the conductors / electrodes of the display.

Elastomeric connector on Wikipedia
