LC-52LE920UN/LC-60LE920UN [3] Caution Cleaning Glass (5) Two people have handling equally by the work. (Maintain it so that glass is not warped.) 1. Glass handling CAUTION: (1) As for handling, wear clean gloves, protective footwear and mask. protective (6) When it is put horizontally, it is put on the flat mat. (2) Inner gloves are covered in the Nitrile gloves. [Inner gloves ] INitrile gloves ] (7) A cushion material is put between glass. It doesn't touch it [the front and the front].
LC-52LE920UN/LC-60LE920UN 2. Glass cleaning CAUTION: (1) Visual inspection is done on the black mat. (2) Dust and trash are taken with an air blow. (3) Dirt is wiped out with cloth. Front side: Moufas Back side: Cotton (clean wiper SF-30C) (4) When dirt doesn't clean, it is wiped out with Alcohol. (5) Dirt is wiped out with the Ethanol and clean cloth. When wipe off a dirt the trace which wiped do not be left.
LC-52LE920UN/LC-60LE920UN [4] How to replace the touch key sensor PWB 1. Replace the touch key sensor PWB in a clean room. Be sure to remove the dust from the unit before carrying it into the clean room. 2. Remove the touch key sensor PWB from the front glass. 3. Clean the bonding surface with alcohol. Depending on the dirt, water solution of 80%vol can be effective. 4. Adhere a spacer before bonding the touch unit.
LC-52LE920UN/LC-60LE920UN iii) Adhere the ITO section to the front glass. (Use the positioning jig.) Tape fixing the FPCB and ITO sections (Adhered by the supplier) iii-1. Peel the release paper of the double-sided on the ITO section. tape iii-2. Slowly adhere it from the end using a roller. (Position the touch sensor using the jig.) * Check that there are no bubbles in the ITO section after adhered. * Adhering error: _+1.0mm iv) Adhere the FPCB section to the front glass. U ill:iiiii ! iv-1.
LC-52LE920UN/LC-60LE920UN iv) Peel the protective sheet of the OCA. Lift the ITO section, then peel the protective sheet by about half by means of the pull tap. * Peeling it completely reduces workability. Check the order due to workability. v) Contact the FPCB and joint end of the transparent electrode film with the glass. * Grasp the opposite end. Note that the ITO is positioned by adhering. *Note: Do not bend the PWB (FPCB section) and sheet (ITO section).
