Well the board is one of the cheaper ones in the set, but its also the hardest to get too. i would call a local service center and ask them what they would charge to replace a control board.. if i had to guess i would say about 300 bucks prob..but i would call around

It sounds like a power surge has damaged the color controller and scan line section of the circuit board. The cost to repair is more then the replacement cost. Next time use a UPS for protection (battery back up for computer and electronics). Regards DaytonComputerDoctor@hotmail.com
Let me start at the beginning---Likely a bad main board in your case but nothing is sure in this type of set.
Main board controls all information to the front screen and communicates to various boards---There really is almost never a simple "that part is bad solution" as any board, the power supply, the main, etc can cause issues.
It can even be a issue with the front screen unit--called a display panel.
You might consider doing some research on the set by Google of the model number with "parts" to get an idea what is available and what potential parts cost might be.
If a main board is bad it will average from one to two hundred just for the part----if issue is the panel you are done--part if even available is more than set cost when new.
That happened to my new plasma TV 30 days after i bought it and the TV repair guy came an fixed it and i saw what he did and he told me that there are 3 circuit boards in back of TV and each one controls their areas, center circuit board was controlling the center screen of my TV which was where the lines were so he replaced it and the lines were gone. this board are usually on the bottom part of the TV and they look alike but they are not due to the connection location., i hoe this help
Hi Thanks for using FixYa. It seems that you might have a backlight and/or an inverter
board issue with this TV set. To start with check the screws on the
inverter boards as if they are loose can cause this issue. To access the
inverter board you’ll have to pull the back of the unit and check the right
side, also check for cold solder joints. It could also be due to the inverter
circuits for the backlights. The inverter is the power supply source
for the backlights. All this is only recommended if you have some kind of
expertise for checking the internal circuitry of the TV as these units have high
voltages running even when the set is switched off. The cost to change the
inverter board including labor would be around $250, if you get this done by a
professional. Please do accept the solution if the issue is
resolved or post a comment for further assistance. Thanks Rylee
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.
The problem is the LCD panel or the logic PCB (printed circuit board). you can find the logic pcb attatched via flat ribbon cables or small plugs. Good luck. The part number should be on the printed circuit board. I hope this helps.
