Ok..here's the deal. I have a Sony laptop with a non-functioning display. When I turn it on the backlight comes on momentarily then goes black then back on again and black again. It will do this 2 or 3 times then stay black. It's ez to rush to the thought..oh its a bad display, replace it. But that is expensive and my not be the root cause. This also smells of a bad inverter. Help, please, before I waste money on a new display that may not be needed.

I know this is a double post, I have it posted in SFF, Notebooks also..but I am desperate and need to cover all the talent pool available on AT forums.
 
There's a couple of things you can try to make sure you got an issue. First do you have a regular computer monitor to output? Plug that in and see if you can manually switch to it. It should be a key combo like FN and F4 or something. You should see a little monitor icon above the key in question. If you can see the display on the other monitor you at least established that the graphics card is ok. Now try to switch back to your LCD on the laptop. You may have to press the key combo a couple of times to cycle it to the LCD Display. Otherwise I hate to say it, something about the LCD is broken. (maybe an inverter or another controller)

I hope that helps.
