Hi everybody,

I have a TOSHIBA M70-340 Laptop and I am facing a problem for the last few days.
When I use my laptop, after almost 1 to 2 hours, it's screen turned to white. Nothing affect on it. Then I have to restart it and it wl start working fine for few hours n the same problem comes again.

Thanks
