Chosen Solution
My wife’s Macbook, a 2006 Core Duo, has developed a problem where the screen will suddenly go white while she’s in the middle of doing something. I am able to remotely look at her screen using Share Screen so I can tell everything is OK apart from her screen. What I normally do is remotely set it to sleep and then sometimes when she wakes it up it gives her the password dialog and often she can continue. Sometimes we have to do this numerous times for it to recover. Is this likely to be the LCD, the inverter or the display data cable. Would probably try the cheapest “fix” first. Thanks.
Most of time a white screen indicates a hard drive failure. But lets look at the inverter first. Move the screen back and forth and see if you get any changes. First make sure you have an external backup of her hard drive. Next hook up your machine to her’s using a firewire cable. Start hers up in Target mode by holding down the “T” key . Her hard drive icon should now show up on your desktop. Run Disk Utilities on her machine.
It’s been a while but I thought I should provide the answer. It was the LVDS cable. Replaced it for about £10 - fixed!
