Question about HP Pavilion dv7-1245dx Notebook
Hp dv7-1245dx has no display, but external monitor works. What should i look at?
Take a look at the function key combinations which toggle the display from the laptop alone, to the display with the monitor and the laptop, and the external monitor alone.
In those combinations, you should find one particular set which gives the key combinations for laptop alone, laptop and external together, and laptop off with external on. It sounds as if you have toggled the last of those three combinations. I do not use an HP laptop, so I cannot tell you which keys are the display control keys on an HP.
On my laptop, they are F5, F6, and F7. My suggestion is to look at your F Keys, to find which ones control the external output, and go from there until you discover the combinations which will contribute to displaying back to your laptop's screen alone.

In your control panel video settings (or right click on the desktop and go to properties, then settings. check your display settings. you should be able to choose between the external monitor and or the laptop screen.

If the notebook's video card (which may be on the motherboard) is successfully displaying images on an external monitor it sounds more like a problem with the notebook display or its connections. Probably the motherboard is OK.
