Re: lenovo t430 no backlight

Hello Guys,
I have a Thinkpad T430s laptop and I am trying to replace the lcd screen. I think I have blown up a fuse or something because I saw a little smoke/spark which came out at the connection. I did a big mistake by replacing lcd while battery was connected (the laptop was off at that moment).
Now, I have the backlight problem where very faint visuals can be seen on the LCD. So, my question is how should I go about fixing this issue?

Any help is appreciated.
PS: the external display monitor works just fine, it...
