The guide below shows the LCD display data signal line tracks from the display EMI filter IC to the corresponding LCD display B2B pin connector.
Repair hints: If the two Display EMI-ESD filter has been change but the problem remains. Do try to rework the display IC marked with number three. Just have the rework station heat controlled about below and not above 350 degrees and have an air flow of 3-5 range. Need extra care for that IC to work with.
