> I hope it's SMPS power supply is broken.
You didn't mention any symptoms but if it just refuses to turn on you are probably right.
One word of caution; finding a bad IC, a failed transistor or diode may only be a sign of the illness. Check every electrolytic capacitor in the supply; there are thousands of failures of some values and if you find some failed, hope for & check the date codes on the replacments and try to avoid the period of 2003 to 2006. There are millions of capacitors from many different companies that have defective electrolyte in them.

If the screen is all white light then you can have a number of problems.
One could be a bad video board, the next could be a simple loose wire from the video board to the back of the lcd screen OR a simple blown fuse on the back of the actual lcd screen can cause the same thing.
Snaps are all sround these things and can be really stubborn at times. Best to start the bottom first then work up each side to the top.
Something flat, thin and with a decent sharp edge on it will help. A pocket knife held parallel to the joint between the front and rear plastic works, you can also sharpen the edge of an old credit card with a file (nail file works) This isn't as strong as a blade , but safer if you slip !!

You are right about the problem on the flourescent, but the issue is caused by the mosfet transistors. You need to use a flat screwdriver to pry the back of the display until you get this open. Start from the bottom side because some damage will be left on the plastic.
