This answer was rated:

I have a Samsung LCD TV model LE40A616A3FXXU the picture quality and colour are good but I have red vertical lines going up the screen from anything that is white like subtitles.
Is this an expensive fix or something like a replacement graphics board ? Or is the screen going ?
Thanks, Bob
Thank you for your question, my name is ***** ***** I look forward to assisting you. Please note, a rating is only needed when we are finished. Can you please remove the power to the TV (so unplug it from the power socket). Then on the actual TV, hold the power button for 60 seconds then release. Then wait 10 minutes, connect the power again to the TV, turn it on and tell me please if it is now operating correctly. Let me know the results please

Done it and still the same.
Thanks It is the internal mainboard that has faulted. This controls the graphics on the screen, its unlikely to be the screen itself as this occurs in the form of dead pixels I am really sorry about this and you are going to have to return the TV to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you. I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know. And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated. Thank you
