Work fine but on the middle of screen have two small vertical lines
Likely a shop repair but:
Either a bad board (main, or power or even a inverter board)
Worst case if Black line and thick would be the panel (screen unit) which would be fatal but is not likely if lines not black.
the problem you have unfortunatly is the panel the cost of the replacement is $3888.00 plus oversized shipping cost. it's part # 23301622. if you still have warranty use it call toshiba for autorized servicer.

One of two things could be wrong.. One is the digital board and or connector. the second is that the LCD display is going bad..

Hello,
All TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times reseating the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em.
Good luck.

You may have to reset the ribbon cables betwen the LCD panel and the T-CON board, very delicate operation if you have never done one and you can easily damage them. http://www.scribd.com/doc/25276757/E40951307-TCON-Troubleshooting-10-22-09-OPT PDF download: http://www.mediafire.com/?zzjygannjty
