Question about IBM ThinkPad T23 2647 Notebook
I changed the inverter and the screen and i still have the same problem with screen it looks off but its not. any suggestions
So the screen is still dark.
see if the video card is putting out a signal. by connecting an external monitor and select function monitor to send signal to it.,
and take a bright light and hold at angle to view lcd screen do you see the desktop dimly.
you may have the rare case of the power/socket to the inverter is not working though I have never seen that in over a hundred laptop repairs.
be certain that the new inverter is not bad , seems more likely that it may be bad..
check that inverter has a gnd and 12volts ~ going to it .
here is a decent explanation of an inverter circuit troubleshooting
its a doc file.
