Why is my screen leaking gum

@satishkuma19438 there is no gum in the screen. This might be liquid coming from the LCD matrix as well. Sounds to me like you are dealing with a bad screen. You will most likely have to replace it. Use the HP Spectre X360 13 4005dx Maintenance And Service Guide to work on it. Page 46 will tell you how to replace it as well as showing you the part number needed for your specific screen.
