Pink and blue vertical lines through

That is asign of failing LCD panel (the LCD controller (T-CON)) board is goin out, it will get worst with more lines. Not much you can do. You can try reseating the ribbon cable between the panal and the Logic board. You can look here to see what the LCD controller board looks like.

They are vertical lines running from top to the bottom, then it can be loose ribbon cable or dirty connectors, or failed LCD controller board (part of the LCD panel assembly, whole panel will have to be replaced).

If the stripes are there even with nothing connected to the monitor, then your display is defective.

LCD needs to be replaced.
Common problem called "Tab separation".

Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan

Hello there!
First things First
1) If you can or have another monitor try and see if the problem persist.
2) RMS the monitor if you keep these problem in these particular monitor.
3) usually these, problems, its cause by a bad capacitor in the monitor motherboard, or resistor.
4) it is best to return the monitor.
