Q:
When replacing screen or main board or other main components, which
aspects should be paid attention to?
1.
Keep the model and the specification of the new material in accordance
with these of previous material. If the panel is replaced by a new one
with different model, the relative parameters, voltage requirements and
resolution should be clearly understood. Attention:Panels in different
model and specification are corresponded with voltage. For specific
information, please refer to the sheet of panel voltage of panel
T-CON.

2.
When replacing the main board, only the
main board in the same model and same production batch can be used.
If using the main board in different model and different production
batch, first should be clear whether the parameter is in accordance
with the panel or not. Meanwhile, pay attention to whether the
voltage that panel T-CON needs is in accordance with the output
voltage of main board’s LVDS VCC. Remember that the panel will be
damaged when the voltage of LVDS VCC is much too high, and the T-CON board
cannot work when the voltage is too low.
3. When
using the main board of different model or different patch for
replacing, the modification and adjustment of relative panel parameters
should be clearly understood. Relative items can be properly adjusted in
the “factory initial setting”. If failed to do so, software upgrading is
needed to meet the requirements of panel parameter.
4. Replacing panel, glass, main board or
shielded wire must be accompanied by appointed technical service
staff.
5. Please mind electrostatic
protective measures: avoidance of static electricity
damaging panel components or IC and other sensitive and
vulnerable components is the issue that maintenance
instructors should pay attention
to.
