I recently changed my hp x360 lcd. the replacement LCD shows the hp logo and goes upto the startup screen where i could enter the user password. as soon as i enter the password the screen starts to flash white continuously. i thought its faulty screen and used a screen from another vendor. but it still does the same thing i could see the hp logo and it starts flashing as soon as i input the password. the screens starts to flash when i go to bios too. i connected to an external monitor and it works fine as i could login and use on the external monitor. after trying for a while the screen does does not show anything now, its just black but when connected to external monitor it shows display. can someone help me out with this issue because i have changed two screens from different vendors.
