windows repair fixes it temporarily. It only started doing this recently,, the screen just flashes white after windows starts up, but before the logon screen.

I have an HP G72 Notebook PC -- the screen also goes to flickering white, but not just after start up; at any odd time. When I close the screen and re-sign-in, it goes away for a while, but always comes back.
Of course, the PC is one month out of warranty!!
What is it?

While dealing with this issue for a customer, I took the laptop apart. Unfortunately this model requires almost a complete disassembly to get to the connections for the video cable on the motherboard and the screen's circuit board/inverter on the back of the lcd screen. When I finally got it apart, I looked at the connection between the video cable and the circuit board. The connection was slightly out on one edge. It wasn't seated all the way into the connector. It was held in with tape. Not sure if the connection worked loose each time the lid opened and closed or if it was originally assembled that way. I removed the connector by pealing the tape gently back and slid the connector from the slot. Then reseated the connection and secured it with the tape. After reassembly of the machine, all seemed great with no more white screen at start-up. So far so good. You can find the manual for maintenance and parts replacement on HP's support website:G72-250us Service Manual PDF
Good Luck and I hope this helps.

Just an update on the white screen. The screen worked for a while but after a year it started to get worse. To the point, it would do it all the time. So the crooked video cable, was not the true culprit. I ended up replacing the lcd screen with a new one. It has been running for a few months with no flickering or white screen. That seemed to be the trick and was not as expensive as I thought. The screen ran under $100. Good luck.
