It is most likely the inverter, here is a trick to check it. Turn the tv on a channel where you have audio(sound)
Take a flashlight or a lamp with a bare buld and shine it on the screen. Look very closely at the screen, if you see a video image your inverter is bad.
Let me know and I can instruct you on replacement.

If you have not tried it: unplug the set and if using a cable or sat box unplug that as well---wait for a while and plug both back to see if a reboot of either cures the problem or not.

I have the same problem. No video just audio.
No on screen display visible either (volume, channel labels) nothing.

Samsung tried to repair this under warranty TWICE within 2 months. Second time they replaced circuit board and it worked for another 8 months. So I paid $1.500 for a TV that died again after 1,5 year - this is ridiculous.

I have no idea what the reason might be and I wont try to fix this since samsung tech could not fix it without replacing circuit board.

LNT4042H TV will not power on. No sound, no video.


Check the power supply module voltages first, it should have 5vdc standby voltage at all time the minute the TV is plugged into the wall outlet, try turn on the TV, then the main 5vdc, 12~16vdc and the 24vdc should be on. Look at the supply for burnt parts, blown fuse, etc.

Howdy,
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 CM811, CM812, CM817 & CS806; 1000ufd 25volts.

Good Luck, big IRISH.

Sound but no picture


you've lost your backlight, the inverter board are part of the panel, so hopefully u just los a couple caps on your power supply. You should check your powersupply for lifted caps.
