LCD problem

Thread Starter 
I have a Dell Inspiron 640m 14.1" laptop. I cleaned screen with foam and some foam flow under the screen frame, where the LCD inverter is. 1/3 of the screen (lower part) started to shudder (horizontal stripes appeared) and after some time this part stay brighter than other 2/3 upper part of the LCD. Motions on the brighter part are slow, mouse arrow movement is like in jelly. Text is hard to read. See added photo about LCD. Is it a LCD problem or inverter problem? What component needs replacement?
Thanks for advance!

Most probably lcd problem.
Inverter is powering ccfl lamp who make light,no inverter or lamp problems can result in this efect.

Try to confirm all is dry. Moisture can physically intrude into a space and then evaporation can be almost blocked because of vapor barriers. Disassembly might be needed to dry out. When dry problem might resolve?

"Line" too straight to be considered condensation issue

Do you guys think the use of a foam is just coincidence then? I never thought condensation I thought moisture (intrusion) could be causing short?

But I really just want OP to get to condition prior to what he thought caused issue. Regardless of open and wipe or blow dry or disconnect reconnect?

Not my area of knowledge.
