Lenovo T430 Screen wont turn on but computer does boot up

2016-05-01, 1:58 AM

First time posting, and not very educated when it comes to computers so bear with me. My screen cracked today on my T430. It still had image on the screen but very distorted. I have a working backup T430. I pulled the screen out of the back up and put in my main comp. My main will boot up (you can even hear the windows jingle but the screen had no power.

 

I then tested both the good screen and cracked screen on the backup T430 and both lit up fine. But neither screen will work on the main T430. i then switched the cable that goes from the motherboard to screen but still same situation, works fine on the back up but not main.

 

I hooked it up to my TV through the HDMI cable and I get the display/homescreen on the TV, and I can use the laptop like that. One thing I did notice is that when I boot the laptop up or shut it down there is a very very very slight change in the screen darkeness. I only notice this because the sun was behind me and shining on the screen. When I noticed this it had the craked screen installed. I tried to adjust the screen brightness with the laptop running but it didnt change anything

 

Do you guys/gurls have any input or solutions? Thanks in advanced

It sounds like you blew the backlight fuse

So, today my T430s screen would not turn on.   I removed the battery and disconnected the AC power.  I then removed the memory cover and took out the memory.   I then reconnected the power cord and tried to power it up.  It beeped a few times. I powered down my disconnecting AC.  Then I put the memory and battery back in and reconnected AC.  Then powered up by pressing f power button and screen worked.
