Re: blue screen flickers and goes almost completely...
Most likely inverter issue, or somewhere in between inverter and LCD, illumination bets thing to do is to take aprt the LCD frame and disconnect and reconnect all wires leading from the inverter. If that doesn't work, the replace the LCD wires and or inverter.

Yep, 95% chance it is the power inverter problem.
If you don't remember the screen having a pink tint or flickering for a
while or being dark at the middle top or bottom before it went, then
your bulbs should be okay.
It will need at least all the capacitors replaced.
I fix many of these types on ebay.
Are you able to see a slight image on it at dusk and maybe with the
help of a flashlight. since your blue light stays on the video board,
may be okay.
It sounds like you have bad capacitors on your powerboard or possibly a burned out transistor on the inverter.
Only way to really tell is to open it up.
If you unplug the screen to video board ribbon, you may notice a different effect in the screen lighting.
There is a chance one of your bulbs is creating a problem
Should the screen happen to light up all white, then your power board
and inverter are okay and the problem may be in the video board.
If it looks pinkish or dark or flickers then the bulbs or a bulb may be the issue.
If it flashes on then goes off, it's in the power or inverter board.
Ok, from the beginning. Can you do a cold boot and get into the bios? (is there an image on the screen then)
Secondly, can you connect to an external monitor and see an image?
Did it do this only when it was heading in to hibernation? If so, it sounds like the power management needs some adjustment.
If there's no image on the external monitor, you may have a video/motherboard problem, or it still could be the operating system/power management.
It all depends on if you have video in bios.
Let me know.
