Check to see if the T-CON board on the LCD panel is getting 5vdc.

Check the caps on the power supply and in the logic board also.

White screen


If the screen is white, try separating your wires behind the computer. Simple but stops the cross-talk of signals.

Step 1:
Fix a White Screen on an LCD Monitor

b>When an LCD screen has turned completely white, there are three normal causes: the screen is defective, the video cable is not connected correctly, or the graphics card on the motherboard of the computer is faulty. You will need to troubleshoot these possibilities to determine which problem you have. If you are not experienced in working on computer equipment, you should not attempt to disassemble your LCD screen because you could easily damage it. Seek professional assistance unless you have experience working on computer hardware.

Disconnect the white LCD screen from the computer by unscrewing the blue monitor cable. Connect the working LCD screen to your computer by attaching its blue monitor cable to the same slot. If your computer display does not show on the functioning LCD screen, try rebooting your computer. If it still does not display, the problem is with your computer's graphic card on the motherboard. Seek professional repair assistance. If your computer display shows normally on the working LCD screen, proceed to Step 2. Unplug the LCD monitor with the white screen. Disassemble the rear panel of the monitor with the small screwdriver. Carefully separate the screws into piles so that you can keep track of how to reassemble the monitor. Locate the internal video cable, a gray cable with a plug on the end that connects to the main components of the screen. See the References section for photos of the video cable for assistance. http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/ Unplug the cable, checking for any debris or blockage. Reconnect the cable firmly. Reassemble the LCD screen. Plug it in and connect it to your computer. If the screen is still white, you have a defective LCD screen. You will need to replace it or take it to a professional repair service for assistance.
b> b> b> Without this test you'll have to guess because as I mentioned before this could either bad motherboard or bad LCD screen.

You'll have to disconnect the video cable from the LCD screen (connector 2) and the inverter board (connectors 3 and 1). After that you connect another working screen and test video. For this purpose I'm using one of my test LCD screens. My test screen is cracked and because of that you see a wide white band in the center but it still works fine for this test.

The original screen is white but my test screen works normal (except the crack of course) and I can see the image. After this test I can tell that the problem must be related to the screen. After I assembled everything back together and connected the original LCD, it's still white. CONCLUSION. In my case this problem is related to the LCD screen and it has to be replaced. b> b>

Laptop Screen faded white


There are a couple of possibilities.

1. A cable has come loose inside the computer4.gif.

2. A cable has become defective.

3. The LCD is defective.

If you wiggle the LCD back and forth and you can get the picture to work again intermittently then answers 1 & 2 above would be more likely.
