No display The TV is on, There is sound but no picture. I know it is not the source because the TV Menu and source indicator (HDMI 1, HDMI 2, Component, ...) does not even dispolay. I can notice the LCD panel is on as it goes from a "ligthed" black to completely black when I turn the set on and off. I can also notice a momentary difference in brightness when I press the source or menu button.

I had the same problem. Unplugged the TV for about 4 hours and when I plugged it back in everything reset and it works fine. I stillh ave a service call open under my extended warranty. I am still going to have the service member come out and look at it anyway.

SAME TV, SAME PROBLEM. SAMSUNG WILL NOT FIX AND THE COMPANY-PLASMA HOUSE-WILL NOT ANSWER THERE PHONE OR E-MAIL, I WILL NEVER BUY ANOTHER SAMSUNG LCD.

I have an LNS4692Dx 46" that i paid $3k for, and did not buy a warranty for. after 18 months, it stopped working. no picture, but sound. they tried to replace the boards, but said i needed to replace the LCD panel. got my quote at $1840. i am writing letters to samsung and best buy to try to see if i can get some kind of assistance...right...

Well I just joined in the world of broken Samsung's. Died Feb. 1st. I had three month additional warranty, but of course it died the day after. Same problem, no video, just audio.

However if you call 1-800-522-7341. This is the number for Executive Customer Relations. They extended my warranty and contacted the repair center for me. Probably won't be fixed by Superbowl Sunday though. I expressed my disbelief that after 15 months a 2400 set can die. I have to call back on Monday for additional help.

I have the Samsung LNT-4661F same problem. the two boards were replaced in sep 07. problem happend again nov 07. just had the LCD planel replaced. Hopefully the problem is fixed for good. If so it was the LCD planel (Ballast) all along.

The technicians arrived today. They opened up the tv and to my surprise there were 2 green boards similiar to a PC motherboard. They swapped one at a time and tested the tv which turned out to reveal that the 2 boards were fine which only leaves the problem to be the lcd display itself. I was told that this part was still under warranty from the manufacturer since the lcd tv is only a few months old to begin with. I was also told it would take 4-6 weeks to order the part and then they would reschedule to install it. Lets see what happens next. I will keep you posted. Hope this helps my model tv is Samsung model LNS4692DX/XAA

I have the exact same brand and model tv with the exact same problem which occurred 9-7-07. I have a repair guy coming on 9-10-07 so once I find out what is wrong then I can tell you what part you will need to fix your tv. Hopefully!

Under menu, option make sure that you haven't selected audion only and that input select is on the first or second options,(not the third one). If you can't even see the menu, then your connections are probably bad. Hope this helps, Mark
