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.
