    Good morning,

    A time ago I powered on my Asus G73sw. Lights go on, fans starts spinning but the screen remain black. First I thought it was a GPU failure so I orderded a new one. Replaced the old GPU and try to power on the laptop. Same problem, screen still black. Than I thought my motherboard was broken. Orderded a new one, disassembled all the components of the old one and assembled it into the new one. Fingers crossed and power on the laptop. Same problem, screen still black. I decide to buy the same laptop on eBay. After a week my parcel arrived. Than I came to the conclusion that the CPU was an I5 and I have an I7. So I switched the I5 for the I7. Now that I have the laptop open I also decided to replace the existing GPU for the new ones I ordered. After assembled the laptop I powered it on and it works :) The new laptop recognized my CPU en GPU. Then I saw that the screen was HD and my screen is Full HD. So I decided to change the screen (sin not to use, right?). Removed the old one and replaced it with the Full HD one. Power on the laptop, Asus logo appear and after that the screen goes blue (think because no HD was connected). So I powered on the laptop again and try to go into the bios. Entering the BIOS was no problem. From automatism I saved the BIOS setting (still no HD connected). Then the computer freezes and I had to do a hard shut down by pulling out the battery and AC adapter. Than I powered on the laptop again........... again a BLACK SCREEN

    Can someone help me?

    It could be possible that the panel itself is on its way out, just based on your troubleshooting that you have shared thus far. I would also consider checking the cable that connects the panel to the motherboard.

    IIRC Some people were able to upgrade the GPU to the 7970m from a later generation. Err maybe that was the 6970m, its been a while now.

    Thanks for your suggestion.

    Both panels (HD and Full HD screen) were working (old and new one). And now no one is working. Both screens stay black. Checked the cable many times and changed it with no result. I guess its something in the motherboards (old and new ones have the same problem)......

    I would suggest maybe checking the CMOS battery. Worth a shot anyway.
