Inspiron 5758 LCD problem

We cannot see the graphic. Only you can. Attach an external monitor to test. 

You dont see it in picture? At external monitor is everything ok

Thanks for answer, external monitor works fine.. 

Welcome to the Dell Community  @Cucooooo 

Until a "Moderator" approves of the photos only you can see them.

Until we can see them try a "Flex Test"

While the laptop is booted and the screen is on.

Grab the display at the upper left and right corners.

Then push one side forward and the other side backwards about 1/2" to 1"

Repeat back and forth. "Flex Test"

Post any change in the display???

Best regards,

U2

@Cucooooo 

External display works fine!!!

"Flex Test" has no effect!!!

Sounds like the LCD display panel???

Let you know for sure when the pictures get approved.

I will check back every once in a while.

Hello. Ah thank you for info :) no its not making any change.. 

@Cucooooo 

Sorry but it looks like it is the LCD display.

The best thing to do is remove enough screws to see the Model/Part number.

This way you can order an exact replacement.

So you saw something like this earlier?  I hope its cable issue because problematic pixels are in perfect center of the screen so uts strange to me

@Cucooooo 

It is something I have seen 100's of times!!!

We save all of our defective laptops.

Then strip them and test every component that we can.

Then those parts are used to refurbish other laptops.

I have seen it many, many times before.
