A customer brought in a Toshiba Satellite A305-S6905 with an obviously cracked LCD screen which is generally speaking a pretty standard repair. The computer was in perfect working order other than the physical damage to the lcd screen. It lit up, I could see some of the windows logo, etc. I took the machine apart, got the part number and manufacturer of the original lcd and placed the order for the replacement. Upon it's arrival I double checked the part # as I always do and proceeded to install the lcd. Once I was finished i checked my connections, plugged everything back in, hit the power and had no backlight. The machine boots up and I can see text on the screen if i hold a light up to it, but thats it. If I remove the new screen and put the old one back in it lights up just fine. That tells me the inverter is good. Do the lcd's/inverters need to be swapped in pairs? Ive done several lcd replacements and have only run across this issue with the Toshiba.
