Cracked LCD Panel
A cracked LCD usually displays black areas, colored lines or ink like patterns.
The panel normally requires replacement.
Black Screen
A black screen does not always mean the display panel itself is broken.
Possible causes include the display cable, backlight, motherboard, memory or graphics hardware.
Diagnosis is important.
Flickering Display
Flickering may come from a damaged cable, panel problem, graphics driver issue or motherboard connection.
Vertical Or Horizontal Lines
Permanent lines can indicate panel damage or connection problems.
Testing with an external monitor can help isolate the problem.
Damaged Hinge
A failed hinge can damage the display cover, cables and panel.
Continued opening and closing may cause additional damage.
Backlight Problem
A notebook may produce an image that is extremely dark because of backlight related failure.
The display assembly should be inspected before assuming the entire machine is scrap.
