We had trouble to name this kind of LCD Problem but from our observation it normally affected CCFL LCD Type screen. Out of 3 cases we found, all the three problem were related to LCD Screen, and not the LVDS LCD Cable or not a Video or Graphic problem.
To troubleshoot this kind of problem simply connect to external monitor, when it display normally on external monitor then it shouldn’t a graphic chip or video problem
can simply reconnecting back the LCD cable to the motherboard and similarly to the back of LCD, moving a bit the LCD cable, when nothing show interruption in the LCD screen while LCD cable was moving, then it shouldn’t be a culprit.
Lastly and most of the time it always an LCD problem, a replacement is need, where you can find all standard type of LCD Screen in our store, while if you can’t find which screen suitable you can always interact with us through +60142871121 whatsapp preferred. Thanks for reading.
