hi, Brand new laptop 1 week old, just fell on the ground. This is what’s happening to the screen: 2 second perfect, 2 second blinking, 2 second perfect, 2 second … etc https://www.youtube.com/watch?v=DgZFqEaO… What should I check? Thanks
Hi @sylviavila , Here’s a link to the service manual for your laptop. Scroll to p.84 to view the necessary pre-requisite steps and then the procedure to remove the LCD panel. I don’t know your laptop but it may be that the LVDS cable is an integral part of the LCD panel and is permanently connected to it and only plugs into the systemboard connector. It could be that you have an intermittent connection in the LCD panel itself. A couple of things to try first. On p.27 of the manual it details how to access the UEFI diagnostic program. In the program there is a LCD test which may help to give a further idea as to the problem. Connect an external monitor to the laptop’s HDMI port and check if its’ display is OK or doing the same as the laptop’s display, just to help narrow the problem down. If it is OK then more than likely it is a LVDS cable connection or LCD panel problem. (Note: a TV, if it has HDMI port, can be used as an external monitor.)
I would start off by checking if the warranty would cover this first. If not then check to see if the cable for the screen is seated correctly on both the motherboard and the lcd. Update (01/04/2019) @sylviavila Since you have checked the cables and they are seated properly, and the external monitor does work I would connect an external monitor up and run the diagnostics on it first Page 27 of this LINK Tells you how to to run the tests. If everything checks out but the laptop screen still has issues then yes my next step would be to replace the screen. If after changing the screen and it still does the same thing then you have an issue on the Mother Board somewhere.
