Hp pavilion ze5500 display monitor still doesn't work
There was no image in the laptop display, but I could see everything in an external monitor bright and clear. Windows was working good too.
So I figure that the problem wasn't the laptop video card, but the LCD.
So I change it for another hp pavilion ze5500 display in stock. But no image. Try setting the brigness with fn + f1/f2 but nothing at all.
I said: "Ok, this other LCD is also bad, I'll have to buy a new one".
So went to ebay and buy a used hp pavilion ze5500 LCD display for $78.
I instaled everything correctly: ground cable; antena cables on the two sides; the power cable; and turn on the laptop. Still no image in the laptop LCD, still everything works fine in a external monitor.
Could the problem then be the video card? I tought that if you can see stuff clear in an external monitor the video card is ok.
Is the LCD I bought from ebay is also defective?
Don't know what to do next. Please help. I'll apreciate your answer.

Re: hp pavilion ze5500 display monitor still doesn't work
IT could be a motherboard problem with the function key that controls the switching of the video infomation between the LCD screen and the external video connector.
It could be the function key circuitry on the motherboard that controls the back lighting levels on the LCD.

Switch the display to the laptops screen. Shine a flash light on the screen and look very carefully for a faint image of what should be displayed. If you see it then either the back light or inverter board is dead. Usually the inverter board. These are housed inside the lid usually runnung alone the bottom of the display. If there is no image then the display is bad. The easiest fix would be to remove the entire lid and replace the whole thing. This will effectively replace all three parts I mentioned, but will be more expensive.
Your backlight is probably burnt out or the inverter needs replaced. The backlight will be a pain in the rear to do so you might want to try a new / used (working) inverter in it first. Hook your laptop up to a external desktop monitor. If you computer boots up, and you can see everything on the external display, you've got an inverter or backlight issue. Shine a flashlight on the laptop screen. You'll see a very dim image of your desktop.
I suggest try to use an external monitor to see if the machine will display an output through the external display, if you have display to your external monitor, it means the LCD on your machine is not working.
these links below have information (drivers, solutions) for your laptop, that will assist you.. review them , i am sure this will give you background causing BLACK display on your screen.
If there is a problem with the LCD display's back light or a corrupted graphics driver, the display may appear blank but the notebook may be displaying information. Attach an external monitor to test the display.
If the image displays on the external monitor, there may be a graphics driver conflict. To resolve this, turn on the computer and press f8 key, then select Enable low-resolution video . If the image displays on the LCD display in low resolution, you can download and install the latest drivers for your specific graphics driver.
If there is an image on the external monitor but the notebook display remains black, contact HP for technical assistance.
If You have External monitor at your place pls connect to your laptop and check whether you are getting external display on monitor screen, if there is no display on external monitor that means motherboard of your laptop might have some problem. if that is the case you have to visit service centre.
i guess the motherboard has gone bad! try reseating the RAM and check, if it starts working then you are lucky or else..... u need to replace the motherboard. for further help, mail me at L2support.firstname.lastname@example.org
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.
