1. Have a new LCD screen replacements and then replace the LCD. Check the lcd flex cable. ensure that cable ribbon is properly pinned to the connector. Replace the whole ribbon cable assemblies if damaged.2. Check or clean the LCD pin connector. 3. Check the inductor coil, and read the VBAT (battery voltage) across to it. 4. Trace the connection line paths of the LCD backlight LED from the pin connector down to the capcitor and resistor where it is being connected. Check or replace also the said components. 5. Replace the backlight LED driver IC. 6. If all of the above doesn't solved the problem, in this level, you may need to rework the betty IC or then replace if necessary. The betty IC holds as the switching circuit of the LCD backlight LED. | |
