Re: T430 DIM DISPLAY ISSUE

This issue is usually a blown fuse on the motherboard

Re: T430 DIM DISPLAY ISSUE

I don't know where it is on that motherboard. Usually people replace the boards, but fuses can be changed. You need better equipment than a simple soldering iron. I usually tell people that I have the minimum equipment to do it. I have a quartz preheater and a temperature-controlled rework station. Some shops do that kind of repair, but it is often too expensive to be practical.  There are often 2 fuses affected.  There is a 0.5 amp that controls the LED status lights and a 2.5 or 3amp fuse for the backlight.  They are often very near the LCD connector.
