How can I fix led tv screen with one vertical red line and no picture?

My Seiki tv is currently showing a backlit screen with one vertical red line. (There is no picture so the menu is not accessible to determine if the line shows over or under.) I have already replaced the power supply unit and the t-con board. The tv is not currently plugged up to any hdmi inputs so I know it is not related to this. What else would be causing this problem? How can I fix this?

Answer this question I have this problem too

Is this a good question?

Whitney,

I think it's either a logic board or the led itself that's messed up.

Did you move the tv recently or anything impact it?

Depending on cost, this could be too expensive to fix and you might be better off getting a replacement tv. If it's under warranty, you should contact the vendor and see if they will repair it.

Good Luck!
