Monitor Problems with HP Pavilion Entertainment PC

The monitor on HP laptop will only work if connected to an external monitor. This makes portability a problem. I was told it needed a "screen" part, but I can't remember what it was. Anyone have any clue??? I just know that the repair shop I took it to wanted $150 for the part and $60 an hour for labor. I figured a new laptop would cost less, just not in the cards right now. I was wondering if i could snag the part from another broken laptop around the house, just can't remember what I need. Please help.

 

There's three parts inside the display.

First is LCD Cable that goes between your laptop motherboard and Display Panel, it also brings power to the Inverter.

Second is the Inverter that changes power from laptop battery to something that the backlight built in the Display Panel can use. (LED monitors do not have this anymore.)

Third is the Panel itself.

Cable and Inverter are cheap, they usually cost like 20usd each while the Panel is expensive and that 150usd sounds like it. (Panel / screen / LCD usually all mean same thing when people speak.)

When laptop is on, shine light to it with a flashlight. If you can see the display but it's very dark then it's usually Inverter or the Cable (use Fn+display key to make sure internal display is in use). If the display is totally "dead" then cause is usually either the Cable or Panel itself.

Inverter and LCD Panel are often interchangeable. Panel of course need to be same size and preferably same resolution. Inverter either fits or it doesn't so that's simple. LCD Cable is the only thing that's usually model-specific.
