You likely got water on the LCD display panel's driver board. The only thing you can do without spending a lot of money is to take the set inside and allow it to dry for a few weeks. If you are lucky enough that no circuits were damaged, the lines will go away. If you are unlucky, the circuit was damaged and the replacement circuit/display panel is as much as buying a new TV.

This is a "screen problem" Worth a try is to remove the LVDS lead at the screen end,..... take great care here, there are nomally two clips each end of the plug. and refit it.
Also the flat ribbon cables to the screen, again take care. Damage to the plugs can write off the panel
This normally causes vertical stripes or errors, but Iv'e had all sorts of strange effects with these leads

Make sure you set the laptop to display at a resolution the TV can display, it seems best to start with 1024x768 then work up.

If you are using a VGA - HDMI converter it is possible you will not get a picture.

You should be able to set the laptop to 1024 x 768, plug it into the TV, select PC input on the TV remote, and the picture should appear.

If not, then check you have the monitor output on the laptop switched on, test it with another monitor to be sure.

If all the above still fails to work, and you've checked the cable the TV has a fault.

I hope this helps.

The t con board or the LCD panels is faulty. Can confirm only by replacing the Tcon board.

Reload or update the driver from the manufacturers website!

Please check the flat cable connections between TCON board and the LCD panel. If this is ok, then it is either the TCON board or the LCD panel itself. Good luck.
