Lenovo laptop with display problem repaired
Received Lenovo laptop with display problem as stated by the customer screen light is coming but only white screen with some lines-see the photos below:
I have connected the laptop on my external monitor for confirming the fault area either it is graphic chip or screen related area.
On connecting to my external monitor I found display is very clear without any problem that means suspected parts is LVDS Cable or Screen itself.
For further inspection I have opened the laptop and checked LVDS cable by removing and reconnecting but there is no change in symptom so now I suspect screen itself.
I have one HP laptop with me of the same size I.e.15.6” whose motherboard is not repairable so I have buyback that laptop for the spares. So for just getting the chance; I have opened Hp laptop for takeout the screen for the testing if I can.
In this process you have to check the LVDS Cable socket size and numbers of pins on the screen circuit for consideration prior of testing. So I took out the screen for finding the possibility for testing.
I found it matches physical dimension and socket specification both are 40 Pins. These both are LED screen with the same connector type so I connected the screen to the laptop and powered up.
And I got this display on the screen-see the photo below:
Display is clear & crisp, so I have ordered the new screen and fixed the problem.
