Question about EliteGroup A530 Notebook
LCD Display is blank and dark even though laptop is functioning.
I fixed it! My machine is a Toshiba Satelite A-105. The screen worked but I could hardly see it because of a very dim backlight. I got to the inverter and tested it with a regular voltage tester. No significant voltage. I bought an inverter on ebay and replaced it myself. It's not to hard to do. I had to take the front screen trim off. There are screws behind the ruber tabs, just pull of the rubber tabs then remove the screws, then work the frame loose by pulling and prying. This can be a bit of a challenge. Once you have the trim off, the inverter is bellow the screen. It has a multy wire plug going into it and a two wire plug coming out of it going to the bulb.

TOSHIBA SATELLITE M35 M35X NO VIDEO FIX
Just fixed three M35 M35X in a row with the same problem, guys. I couldnt find anything online that gave me ANY CLUE. Video card is bad, right? Wrong. PASS IT ON TO OTHER BLOGS PLEASE, I will get it started here.
Heres the fix:
This requires access to the cpu and heatsink, remove the keyboard and palmrest to access the motherboard, I think you have to remove the screen too. Remove the heatsink and cpu. Reseat the cpu, heres the kicker, press firmly on the center of the cpu while turning the locking screw. Pressing the cpu hard, allows the locking mechinism to get a good bite. Turn the locking screw hard into the end of the turn. Hook up the heatsink and set it back on top of the cpu. Press down on the heatsink over the cpu, fairly strong pressure.
Now test the motherboard, use just cpu, heatsink, memory, power button board and cable and external monitor, you can use your screen instead by just hooking up the cable to motherboard, leave the screen laying flat on the table. Now push the power button with one hand and the other is still applying pressure to the heatsink, no you dont need to screw it down yet. Keep reseating the cpu with varying degrees of pressure if you dont get it go the first time.
The trick will be to get it all assembled with the same results.
There seems to be a problem with the cpu seating correctly, it must come loose and the laptops exhibit the symtoms of no video. It might even be neccessary to insert a wafer thin piece of copper or something in between the cpu and heatsink if the heatsink doesnt apply enough pressure to cpu to keep it seated deep enough to run the computer.
Am I a genius or what, lol. I am not, but I am sure surprised no one else has posted this info over the years.
Hope this helps someone with this frustrating problem with the M35 M35x and many more models.

On my Evo N610c you could see the initial boot screen and then the display backlight would switch off. It ran fine on an external monitor, but no amount of pressing the key combo to switch display outputs would persuade it to use the built-in panel.
In the end I discovered it was the switch in the front of the case that detects when then lid is closed. Using a flat bladed screwdriver to actuate the switch a few times was enough to bring the display back on-line. The switch in question is in the hole just below and to the left of the touchpad. Simply inserting a screwdriver is enough to make/break the contacts. I suspect it gets filled with grime over time.

What might also be the problem is try adjusting moniter brightnesss(blue function key+F7/F8). If brightness does not improve, report the problem to HP.

This could be a faulty Backlight or Inverter. These are both quite difficult to repair if you dont do them regularly. Any decent Laptop Repair Shop will be able to fix this for you.
