Hi,

I have an interesting case. I have a older Sony Vaio laptop (VGN-FE550G). One day the screen suddenly darkened. I restarted the computer, I would have a picture for about a minute, then the screen would darken again. I took the computer apart, removed the old inverter, and installed a new one. The laptop seemed to work fine for about 3 days (although I did notice the brightness would flicker every once in a while). Then once again the screen darkened, though it would keep a picture for about 10 minutes when I rebooted it. I could still see faint images in both situations. I currently have the laptop running off an external monitor, and it is working fine - awkward for me but possible. I am very frustrated with this problem. I need some of you experts out there to help me figure out what's wrong?

Please help.

I didn't find the right solution from the Internet.
