USE CAUTION WHEN HANDLING THE LCD PANEL
When repairing the LCD panel, be sure you are grounded by using a wrist band.
When installing the LCD panel on a wall, the LCD panel must be secured using the 4 mounting holes on the rear cover. 
To avoid damaging the LCD panel:
do not press on the panel or frame edge to avoid the risk of electric shock.
  do not scratch or press on the panel with any sharp objects.
  do not leave the module in high temperatures or in areas of high humidity for an extended period of time.

(High voltage occurs at the inverter circuit at 650Vrms.) 
  always clean the LCD panel with a soft cloth material.
  use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short. 
  protect the panel from ESD to avoid damaging the electronic circuit (C-MOS). 
  during the repair, DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth.
