1. on safe mode no flickering.
2. external LED via HDMI port, no flickering.
3.on normal mode when i change the setting of brightness level, flickering rate increases.
4. when i remove laptop's display cable and again plug in, screen works properly for next 4 to 5 days and then again flickering gets started

    Sounds like dirty connector contacts at the mainboard connector and at the base of the screen connector. Both connectors should  be re-seated at least a half dozen or so times to help clean the contacts. Make sure you disconnect the battery when you do this. The screen bezel and hinge cover must be removed to access the connector at the base of the screen.

    Hi Chunouti,

    Try to do power drain,

    1. Shutdown the unit.
    2. Unplug the cables connected to the unit.
    3. At bottom of the unit there will be a small tiny pin hole with a battery symbol close to it. Take a pin or a paper clip insert into it you feels like pressing a button hold it for 20-30 seconds. ​
