laptop backlight question?
After drying it all day we took it apart and noticed the bleach had corroded the usb port. I remembered in my college days that shorting a usb port will cause power supply to cut off. So i said lets get some CRC QD cleaner and just clean the corrosion and it should work.
I couldn't get any electric cleaner but the people who work across the street had some non chlorinated break cleaner. We used that to clean as much of the corrosion as possible off the usb and noticed some on two of the chips on the motherboard had corrosion. Spent about 20 min cleaning each pin on the chips to separate them and tried powering it again.
(at this point the laptop is mostly apart and just got bare essentials put together). It worked, fans started spinning and screen flashed its toshiba windows didnt shutdown logo.
I begin to assemble it as much as possible without putting any screws in. I got the keyboard in and every electrical component. i mashed the power button and the backlight on the screen wont come on. I can see the text on the screen change but no light.
Take the keyboard out and it works normally.
Can someone help me, or got any pointers? I'm away from home so I dont have access to fancy equipment like tooth brushes or contact cleaner.
