ACKNOWLEDGMENT - THIS PROCESS BREAKS ANY GUARANTEE THAT YOUR LCD MAY HAVE, THEREFORE IF DAMAGING I DONE I DON'T HAVE ANY RESPONSIBILITY ON THIS, SO TRY ONLY AT YOUR OWN RISK.
1º step
With the LCD in top of a secure table, repair at the metal frame that protects and secures the LCD is imprisoned to the PCB with the Chips with some small metal clips folded, is necessary to put them right with the help of a small pliers in order to be as they are showed in the pics.
1ª pic - In this pic can be seen lcd of the behind part, the small metal clips that I speak in the case of this LCD are indicated in image.
They must of being folded as below in order to be well right.
In the end of this process our LCD must be with the small metal clips all as pic below.
2º step
Until now was easy , now comes the most delicate part ,to remove the metal frame and to remove the polarizer that is glued in the superficie of the LCD, this process must be made with very well-taken care in order to not damage the LCD nor warping the frame or small metal clips , therefore this would result in an imperfection of the consequent support and for bad contacts.
-- Removing the frame --
With the fingers in the small metal clips, now push them in the direction of the LCD along body of the LCD uniformly in order to dislocate the frame, till the small metal clips will be at the surface of the PCB.
It has to have be taken care in order not to force very much the suface or you can brake the LCD!
If everything ran well until here after removing the frame well , you must have something of this type.
Now comes the most delicate part , to remove the polarizer of the LCD, (Please have attention the position where was the LCD previously in order that when you mount it, the characters are in the right places )remove this pelicule with a xizato or a sharp knife.
After the previous step place the xizato gently betenw the polarizer and the LCD , to be able to raise it a litle for you to be able to grab it with your thingers and pull it gently till it come right
Pulling the Polarizer:
When you have polarizer unglued from the LCD, it has that to be clean very well in order to remove the glue that was under it, this can be made with a cotton absorbed in alcool in order not to scratch out the surface of the LCD, in case there are any residues of glue in the LCD, they can be removed by the same process efectuated in the polarizer
After this verify if the orientation of polarizer, that in the case of your LCD it is with the old color off the characters (in this case black or blue ) (inverted) and the characters passed to be of the color of the old backgound color (blue), in some rare situations are some LCD companie tha is requeires to buy somo polarizer sheets due to the original ones only make the desired efect by being rotated by 90º .
Example of an new Polarizer sheet .
Well , if all went great tiil here lest pray to all the siant to our LCD to go on roling ,and there are no leftover parts after asembling it again
For that put the polarizer sheet in the correct orientation acording to you LCD , and then fix it with a bit of scotch tape (glue tape) in the extrermes of the LCD so it doesn't moves in the mounting process.
Polarizer put in the correct position.
Polarizer fixed with a bit of scotch tape.
Aliging the LCD in the corect position in the board.
Mounting the protective frame again , don't forget to tight th metal clips has they were originaly in the LCD.
If all whent well your final result should be something like this
hope you are lucky to make your own
