Follow proper grounding procedure
Warning:
Make sure to follow proper grounding procedure when involved in Plasma TV panel replacement.
Many electronic components used in this Plasma TV are very sensitive to Static Electricity.Further
damages can be caused to the set if these measures are not observed.
Electrically conductive wrist band, bench top mats, floor mats, toes/heels grounders, paint and floor
finishes are recommended as measures of prevention against electrostatic discharge.

Front Cabinet Removal Only (TH-42PX75U)
Follow this procedure when only removing the “Front Cabinet”.
If the front cabinet needs to be removed for glass replacement or for any other reason, it’s not
necessary to disassemble the entire TV to do so. This can be done by only removing a few screws
and a few connectors. (For illustration, see the picture on the next slide)
1. Remove the screws securing the TV’s rear cover
2. Remove the rear cover
3. Disconnect the left and right speakers wires.
4. Disconnect connector A1 and A52 from the A board (Release cables from the clampers as
indicated on the picture of the next slide).
5. Remove 6 screws from the panel and 4 screws from the stand bracket.
