Some replacement LCD screens do not come with the plastic frame. The original frame is easily separated and reused. Push the LDC out of the frame from behind. This takes some force. Be careful not to break the frame.

After separation, removed the sticky material between them and replaced it with double sided tape.

On reassembly stick strips of the tape to the inside edges of the plastic frame and then trimmed them to fit with a Exacto knife.

The small flexible cable must be folded around the inside edge of the plastic frame and then folded again to meet the connector. Follow the folds of the original cable.
