I installed a new screen on my HP G71-340US notebook and all I get is a white screen, what can I do to fix this?

1) Check if the laptop is able to be shown on an external monitor. If it shows up, then it is a screen issue on the laptop.

OR

2) But if it doesn't show up on the external monitor, then its video problem on the laptop motherboard. The video chip is part of the laptop board, it solders on. So its not user replaceable like how it is on a desktop.

Desktop video, if the on board/discrete card doesn't work, then you simply get a video card and plug that into the computer. Install the new driver after removing the existing driver (on board or old video card) and then your good to go.

It appears you have a faulty notebook. This can happen if the notebook come from the same batch of units that could be faulty.
I suggest you return the notebook to the store and get it fixed under warranty.

try displaying monitor on external screen. if it is present then it is the video card and motherboard failure.

if it is not present on external screen then it most likely needs a new lcd.

Try this to narrow down the problem. New screens are approx. 70-140 bucks on ebay, inverters are approx. 20 bucks.

the cheapest option is to pick up a new one on ebay and install it yourself. Let me know if you need help with the replacement procedures

If you find the same white line in the BIOS screen, we can confirm that it is the problem with the LCD Screen of the notebook.

To enter in to the notebook BIOS uility, start it and keep on tap F10

It is likely to be either a faulty screen or a faulty screen cable. As the backlight is working and only the data is missing.

is it not coming on at all or is it just a white screen??
