Hello, I have a Asus to repair for my hobby.
But I don't have a image on screen. Not even with VGA connected.
The laptop powers on, charging batt. And after a few min. The CPU fan kicks on.
I already replaced the CPU but its doesn't work. What have I already done.
>CMOS batt removed, memory bank removed, keyboard removed, cd/dvd-rom removed, WLAN removed, cpu replaced by order same type on ebay.
Could be a back light issue. Test by turning on and shine a bright on the screen and look for very faint images, you will need to look at the screen from different angels.
This video shows the test being done to a tee vee, different product same priceable.

Already tested.
The laptop react like there is no memory banks in it. I have tested with working memory banks. But it doesn't come to life.
I think there is no problem with the display inverter. I think it get no power at all.
Only power for some componentens for the motherboard like, batt charge Power on, fan that kick in at few minutes. I don't understand the problem.
@Vinnie Do you have a multi-tester? Test where you have power and where it stops having power. A loss of power somewhere is stopping it from doing what it's supposed to do as far as turning on and at least lighting up the monitor. Start right where the charger plugs in and follow the traces testing at every component. It's best to do this using the charger as your power source so you know you have the correct power.
