Lenovo U430 Touch Display Issue


I am having a problem with my Lenovo U430. Unfortunately for me, despite the notebook is still under factory warranty, I don´t have an official Lenovo Service in my country. So I´ll have to manage myself with this issue.

The U430 starts up in a normal way but the screen won´t work. I plug it to my LED tv with an HDMI cable, and the computer works fine, the problem is in the display. I am wondering what could the problem be, I read something about the video chip or something like that, could be failing on the motherboard. Is there anything that I can do to realise what the problem really is??? I prefer to resolve it miself rather to let anyone open up the computer and make the thing worse than they already are.

I am sorry if my english isn´t the best, I think that I manage to explain myself just fine.

Re: Lenovo U430 Touch Display Issue

Hi alemano , 



Welcome to the Community Forums. 


If the laptop is showing display using your external TV then most likely the graphic card would be performing well since external projection of display is an advanced feature .


The problem may be the LCD or LCD cables that you can try to unplug and replug checking if there are impinged cable along the way and in the port.


Herewith is the hardware manual that can help you on the disassembly of top , bottom cover and LCD panel.  

The user guide here and service training video would also be a good reference. 


Take time to review the steps .

Hope this helps you in your steps.

Update us as it goes.
