Hi,
Is it Samsung LN-S4041D model as shown in question or any other model?
Thanks.

A discolored screen, such as pink in your case, implies either:

 

1.) The motherboard and/or video processor of the TV has malfunctioned. 

 

2.) Your input device is rendering the pink screen, such as a video game console for example.

 

If you determine that your input is not the reason for the pink screen then you need to contact Samsung for a warranty replacement.

 

Samsung offers a 1 year / 12 month standard warranty, and some of higher model TV's have a 3yr / 36 month warranty.You can find out your warranty information by going to http://www.samsung.com/us/support/#Also if you have purchased the TV in the last 30 days you can purchase a Squaretrade warranty which will refund the price of the television if they can not fix it. www.squaretrade.comI hope this helps!  Thank you for using FixYa!

Defective panel, or bad ribbon cable that is associated with the color lines. ribbon cables are at the bottom, or th sides and will be in line with the color lines on the panel remove cables clean and reinstall.

The way to fix this failure is to replace 4 capacitors on the power supply. If your LCD has the power supply BN44-00135A in it, check the picture below to find the location and value of the capacitors.

Make sure tv is on channel 3. Make sure cable box is on. And cycle slowly thorough the inputs till the picture comes back.
