The screen unit is called a display panel and if available the cost will always exceed the cost of a new set, not to mention some are sold on an exchange basis and have a core value.
If your TV have sounds but no picture or image only white screen..
The possible problem is T-CON board..T-con board is the responsible for picture on LCD TV..
Please try to replaced it to get your TV back to normal operation... For specific parts and easy find the it online kindly get the part # of the said board (part # is located on the board itself printed with sticker)..
you can try through LG support which would be through www.lg.com or you could try the display division www.LGDisplay.com (slightly differant in several countries)
A replacement screen is not going to be even close to cheap. I would expect that a new TV would cost lest.
Hi, It is hardware issue related to LCD Panel (screen). Regarding fixing it, it depends if you are handy with electronics stuff repair and can replace circuit boards in tv etc then please check T-Con (lcd controller board) on top center position at rear of lcd panel, this board would be covered with metal shield. Need to take off back cover of tv to get access to T-Con board. If T-Con board does not solve lines problem of screen then LCD Panel is bad and will be replaced. If you fee uncomfortable doing so then repairman option is better choice. Hope this info will help you. Thanks.
First you can try adjusting the cable to the LCD Controller (LCD CONTROLLER 6870C-0080D from LG 42LC2D) Sometimes the contacts get out of alignment and disconnecting/reconnecting it will clear it up. Do not touch the contact points. If this does not work, you may have to replace it.
