My first thought would be to check your TV on multiple inputs to verify that it IS the TV and NOT isolated to your input cable(s). If you can get a solid blue color to come up on the screen by changing inputs then it would really narrow down the issue(s).
Hope this helps.
Take ur hand and pushes all around the tv frame bazel see if the veritical blue line react like flashes or lighter or darker,than this tv can not be repair at all because the LCD screen itself it is the caused,the LCD screen cost same as a new tv if it is require to be replace.If there are no reaction of the blue line at all than ur tv have a circuit board problem.The T-CON board is dying,this board sit in the middle bottom of the LCD screen,must be replaced will solved this problems.Tries websites like Shopjimmy.com,Ebay.com to buy a new refurbish T-Con board for the replacement.
Let's see if I understand the problem: when you have a blue screen, you see at least one black vertical line in the center, and when you have other material on the screen the same line(s) is yellow (or conversely, you have a blue vertical line that stays on all the time). If I have parsed your complaint correctly, then you have a bad connection in the LCD panel or a bad LCD column driver chip. It is possible that an expert technician can solve a connection problem by "massaging" the connection or taking it apart and reassembling it, but sometimes this only creates more problems.
Replacing a failed LCD panel driver chip requires specialized equipment. Search for "LCD TAB repair" to find a company with the right tools.
Modern televisions have screens divided into sections. Each section controls all the rows in its area, and it is controlled by its own video separate video driver. If you are missing a line in a section, then a problem has occurred with the driver board in that area. It will be pretty expensive to fix, I hope your warranty has not just expired!
Both sound like bad LCD panels. The following must be answered to confirm this: Do the lines appear on all inputs/all signal sources? Can they be seen in the OSD/menu? If yes to both questions, it is likely that the LCD panel is bad
