Sound like one of two things: A test screen, or a broken TV. More likely than not, your television is broken. Try hitting TV/Video on your remote, and if that doesn't work, power the TV off, unplug it, and plug it back in. If none of the works, it's time to call a repair man.

It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.
Thanks for using FIXYA, big IRISH.

I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!

The cause depends on how you use the tv and what are its connections.
If you are using a box of any kind then the defect is in the the connection: either the cable connecting the tv to the box is damaged and it will have to be replaced or the selected input in the tv's menu isn't the one actually used - this happens when you use a Composite or S-video connection and you have selected as input the Component or the RGB connection. In that case just select the correct one. Of course i've assumed that you have correctly plugged the cable.
If you are using the tv directly from an antenna or the cable then the problem is in the tv system used: it should be NTSC or automatic and it's set on PAL. Depending on the exact model of your tv this setting can be found in either the Setup section (usually under the Country or System options) or in the Video. To fix it you will need to go into the Menu, find it and set it correctly.
