Hello guys, I'm staying at my friend's house while I wait to move to my apt, and today I turned on the TV (LNT3232H) and I can see video for about a sec and then the screen goes black but there is sound, I pushed menu and can't see it, try to change channels, change sources, nothing. Checked all cables, unplug and plug back in the tv, none of these things worked .

Do you guys have any idea of what could it be? Is it the lamp that needs to be replaced?

Thank you for your answers
