LCD displaying vertical lines and red dots

Hi Guys, i need help.

i got the macbook pro 15" mid 2010 model with i5 processor, which is affected by defective graphics card so i just got it replaced by apple. this issue was present before i brought it to apple and thought it was the graphics card issue.

when the repair was being done, the apple genius rang me and informed me that after the logic board replacement, the screen was still displaying the colours and said i needed to replace the lcd assembly for $500 so i didn't change it.

so now i am trying to figure out the actual issue. can it possibly be lcd connector, inverter or the actual LCD?

i have attached some pictures of the screen. it displays red dots where it is black colour and blue vertical lines on white space as you can see on the images attached

Please help me figure it out so i could fix this issue as cheap as possible

thank you for the help in advance guys!

When connected to and external display does the same problem present or is it normal. If normal the problem is in the display chain you mentioned. . . but I believe you don't have an inverter board you have a LED controller board.

Thank you for answering!

Screen works perfectly when connected to external display. So do you think I need a new LED controller board or new lcd?

Try this: Press Shift key when your Mac starts boot into safe mode. If the problem appears, it could be a display problem, and if it doesn't appear, it's likely an unsupported third-party kernel extension

Sadly yes - it follows what the Apple Genius told you. . . you can pick up a screen and do it your self (it's an advanced project). . . but check out the costs you might find someone/someplace that will do it for less than you can.

Does the display image change when altering the angle of the display up/down or slight corner twist? If it does you could try replacing just the LVDS cable first. LVDS Cable. Otherwise it's the LCD display drivers (part of the LCD).
