Laptop dim screen

[Hanabi]

GOOD NEWS! I TOTALLY FIXED MY LAPTOP, have to take it all apart and heat up the video card with a hand torch!!! SAVED ME 400!!

BUT! the screen is so dim, you can barely see it. I test it on a external monitor and it works perfect.

So it got to be the screen, i am not sure what though, probably has something to do with the inverter, or i dont know?

i really dont know how to test the inverter....

Any comments?

It's not the screen, it's the inverter for the backlight.. Even your backlight can still be ok.

I have the exact same problem with my old laptop, which is now my idle server :D

Depending on how new your laptop is, an inverter can easily be bought but is surprisingly expensive for the part they are. They are located below your screen in the screen housing. Screw it open and follow the cable for the screen from the laptop body to the screen housing... a small flat cable with like 10 little wires (it looks like a mini ATA cable) goes into a sort of elonged print plate. That is your inverter and has probably died. The output should be around several thousands of volts as it converts your 12 volt laptop power to something like 2000 Volt for the backlight (don't ask why it needs that).

Specific laptop number etc and it's googable, but expect prices of 100 dollar and more.

Yea i figured its the inverter too. I searched it on ebay, and it could be as cheap as 6 dollars :3 some are 12 dollars. Hopefully they works, the model number matched :D
