8) 
Use care when handling the wires or connectors 
of the inverter circuit. Damaging the wires may 
cause a short.
9) 
Protect the panel from ESD to avoid damaging 
the electronic circuit (C-MOS).
10)  During the repair,
 DO NOT leave the Power On 
for more than 1 hour
 while the TV is face down 
on a cloth.
USE CAUTION WHEN HANDLING THE LCD PANEL
When repairing the LCD panel, be sure you are grounded by using a wrist band.

2) 
Do not scratch or press on the panel with any sharp objects.
3) 
Do not leave the module in high temperatures or in areas of high humidity for an extended period of 
time.
4) 
Do not expose the LCD panel to direct sunlight.
