My screen is showning flickering white lights
To confirm that indeed you laptop CPU is working normally, you can try plugging an external monitor. This will also verify that your onboard video or memory is not the issue.
Assuming you have tried the above, as to the screen flashing, it can probably be the LCD panel display. It can either be the video converter or your backlight inverter (or CCF fluorescent tube). Any of the two would require opening the display panel and component level repair. Should you not be comfortable cracking the display open and circuit analysis/diagnosis, you may need the services of a qualified professional.
Hope this give you an idea and work out for you. Good luck and post again how things turn up or if you need further information. Kind regards. Read More At : TravelMate C312XCi Tablet PC...
