A laptop is
mostly used tech device now days and quite expensive as well. The screen is the
most delicate part of it and can damage easily due to hard external force. But
many times any damage on external screen leads to no output on it does not mean
the problem lies with internal hardware as well. Laptop screen repair is
considered as major task and the technician needs extensive knowledge of the
subject.
But at initial
level you can troubleshoot with easier steps and rectify problem so, it will be
easier to approach technician with exact cause. Few of laptop repair stores
offers free diagnose but many not so, basic troubleshooting can save your
potential time along with money.
If the power
light is glow then try to press caps lock button on the keyboard few times. If
the button light glows and turned off then you can be sure that the problem is
limited to external screen or display and not with the internal system. Then
try to adjust brightness from low to high if you will be able to see display
within it then the lightning is not sufficient to clearly seen screen of
laptop. If these methods will fail then connect with external monitor and if
you will be able to see the display then surely considered that problem lies
only with external display and not with internal hardware.
