Repair dead pixels on LCD display
There is nothing worse than partially working LCD even if just one pixel is is not working. Although this method can not be applied on LCD monitors and larger panels, it gives great results with those small 7-segment and graphical LCDs.
On any display that doesn't use rubber zebra strip, heat seal connector is probably used. Heat seal connector is a self adhesive tape with conductive lines printed on it. With the help of glue on this tape a contact is made with the glass LCD panel. After some time, this glue dries out and it is necessary to re-activate it by using hot air and applying small amount of pressure. Here you can see a successful attempt of fixing a cordless phone's LCD panel using this method. Instead of using hot air, clothing iron can be used as well as soldering iron with a piece of cardboard on it's tip to distribute the pressure evenly.
