DV5-2035  No Video, External video works fine

A DV5 arrives with complaint- 

Video shows on External but not internal video on LCD/LED display.


Inspecting the unit near the video section, 
the problem is immediately spotted as being a blown transistor. This transistor is one of the switching type that allows the video signal to be displayed/sent to the display. Without this part there will never be any video shown, except on an external monitor.

Solution: replace blown transistor
