Casio CA-851 LCD Panel Replacement

Post06 Apr 2014, 19:00

Hello guys,

Here is the picture...

Image

I am replacing an LCD for a good friend, and during an LCD swap for this "Casio CA-851" I ran into a bit of a problem, and hoped that one of you could help me with it. The problem is that replacement LCD does not seem to have the "patch panel" extension that allows the LCD to make contact with the circuit board. I have seen this configuration with the Seiko M159-5050, but the replacement LCD's come with the patch panel extensions. Is there a way to remove those extensions carefully, and attach them to the "new" LCD panel? Will I have to go back to the seller, and ask if he has mistakenly shipped me the totally wrong LCD panel? If anyone has any good/bad suggestions, I would greatly appreciate it because it is for my friend.

Thank you all,

- Patrick

I usually just remove the zebra strips from the old LCD and reuse them. Just bend them away from the old LCD and they'll come off :)

Hi dutchsiberia,

So, is there a "sticky" solution on the LCD side of the zebra strips? Will it remain sticky after I pull it apart? The reason I ask, is because with these Casio 134 modules, there is "no" gravity to help out like with Seiko modules. You have to have the zebra attaches when sliding it underneath the plastic LCD holder.

I've taken countless screens off over the years, practically every one has the zebra strips stuck to the glass, but I've never come across any that had any kind of glue on them, I just assumed they got stuck there over time?

Are you sure the holder doesn't come apart in any way? It doesn't sound very practical, even in first manufacture, unless they put it all together then sealed the holder around it?

Richard,

If I pull the zebra stripes away, how do I realign them to the new LCD panel? With the 134 module, there really is not a "trench" for the zebra stripes to sit in to auto align them.

Here is a picture of the underneath side of the Casio 134 module, and I have pointed out where the "zebra stripes" are in relation to the LCD panel.

Any ideas from the picture?

Thank you all,

The zebra has a flat side (lcd side) and a not so flat side (module plate). check it out

Can't you just sit the zebra stips in like in the pic above then just reassemble on top? as long as they stay where they are they shouldn't go anywhere once it's all back together.
