My samsung 46d-7000d TV has blue or violet verticle lines and if i wont switch on the tv for complete 2-3 days no lines will appear for another 2 to 3 days what will be the cause

Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

The display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
Hope ya fix it!

Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

Need to check the two things.

1st -- need to exchange T-con Board.
2nd -- need to exchange the cables between T-con & LCD panel or
between T-con & Main(LVDS cable)

I talked to a Samsung support helpline and it needs to be taken to a service center for repair.
