+ 0 Votes screen Problem Timian 4 years ago sounds like the backlight for the LCD is out. You might be able to find a replacement LCD on E-bay if you are not under warranty. + 0 Votes Inverters are possible to replace, the bulb itself is VERY tricky robo_dev 4 years ago ...well let's just say that this is VERY difficult. I repair all sorts of electronics and would advise anybody not to try it. the bulb itself is a $30 part that is about the diameter of a coffee stir-stick. On most displays you must carefully un-stick glued on ribbon cables, carefully unplug VERY fragile ribbon edge connectors, then do a very neat job soldering the wires to the new bulb. I tried to fix one this way, and it was not a successful repair. The inverter is not a big deal, typically just a little module tucked into the frame of the display. Take off the frame, unplug the old one, plug in the new one.... + 0 Votes FL inverter board? Jacky Howe 4 years ago Look at the LCD screen very closely and check if you can see a faint image on the screen. It?s possible that the LCD lid close switch stuck in the ?closed? position and the backlight stays off even when you open the LCD screen or turn on the laptop. The switch turns off the backlight when you close the LCD display to save the laptop battery power. Check the LCD lid close switch. Usually it is a small plastic pin located close to the LCD hinges. Try to tap on the switch a few times to turn on the backlight. If after tapping on the LCD lid close switch the backlight stays on, you fixed the problem. It is also possible that after tapping on the LCD lid close switch the backlight works fine, you see a normal video on the screen for some time and then the backlight turns itself off again. In this case I would blame the FL inverter board. Try to reseat cables on both end of the FL inverter to make a better contact between the cables and the FL inverter board. If it doesn?t help I would try to replace the FL inverter board.
