Hello, i have one Lenovo 4233-5HG laptop and the problem is that the lcd shows strange colors (see the attached pics) and also shows green color instead of black.
When attached to external screen it is working fine so it is not vga issue.
I thought it was the lcd so i replaced with a new one but the problem remains.
Now the only solution that i have is to change the LVDS cable from lcd to mb.
I have checked the cables and connections and all seems ok.
I do not know what else to do. Need your help. Thanks

You say an external monitor is OK, so it is not likely the driver or the motherboard.

In addition to changing the LCD display, there is a high voltage inverter and a cold cathode tube to light the display. Either of those may also be defective. The cable could have an internal fault and so checking it may not reveal a problem. You should also try changing the cable.

it may still be the motherboard, since the video outputs for the display, and the external one are not the same
