| Samsung LCD TV No Picture but has Sound
Hello all. I have had my Samsung LCD TV for just over a year. (of course, just enough time for the warranty to expire) I go to turn it on this morning and the picture turns on and then the screen goes black. The sound still comes out of the TV perfectly fine. I cannot see any of the menus or anything when I change the source either. I've tried unplugging the TV for a while, plugging it into different outlets and even using a different power cord. None of these have seemed to help. Am I looking at a costly repair? I've read things about back lights going out, power supplies being bad but I have no idea. Any and all insight would be greatly appreciated! |

said by Adamd2 :the picture turns on and then the screen goes black. The sound still comes out of the TV perfectly fine. I cannot see any of the menus or anything when I change the source either. It seems most likely that the problem is either the backlight itself or the power supply for it.
However, I presume that there's no "glow" around the edges when the picture is black? If there is an indication of the backlight working ("glow") then the problem could be anywhere in the video circuitry that drives the panel and that would be pretty much beyond the scope of anything we could help with here. |

1 edit | Thank you for the responses. I left it unplugged all night so I am going to go check out what happens. I'm sure nothing will change but I will look more closely at the screen and see if there is anything I can see. It's probably something major and will cost a lot. Yay technology. Thanks again!
*EDIT*
So I plugged it in just now after leaving it unplugged for almost 24 hours and it seems to be working. We'll see if the screen goes off again at some point. I had unplugged it yesterday for about an hour or so as I had read online about recycling the computer chip inside but that didn't help. I don't know why 24 hours would help or what changed but thus far it is working. *fingers crossed* |

I have been having the same issue with my Samsung LN-T4665F. The problem first surfaced about 3 weeks ago. Same symptoms regardless of source. I even fed the TV cable directly from the wall to the TV as Samsung's customer service rep insisted my problem was not with the TV but either with the cable box or my HDMI cable. I disconnected the power overnight and the TV began working again - until today. Again, no picture, but sound.
Customer Service so far has been no help. My TV's 12 month warranty just expired, but it was supposed to be extended by 3 months because I registered it online. Customer service asked me to fax the bill-of-sale for proof of purchase so they could give me the 3-month extended warranty. But strangely, they can't ever seem to locate my fax. I've sent it on three different occasions now. I'm beginnng to feel they're giving me the run-around.
If you registered your TV online, you too may be entitled to a three-month extension. |

This issue seems to be rather prevalent with the Samsungs. A quick Google for Samsung LN-T4665F "no picture" turned up a number of them. These are some of the more interesting ones:

Hopefully you'll have better news than this for us.
EDIT: For your "why 24 hours" question, one of the links above says that 4 hours unplugged is what's required to reset the electronics in these sets. |

| I am not liking the sound of this at all. So far TV worked all day but reading all of the comments I am beginning to really worry. I actually filed a claim with my credit card company and am going to give it a week before canceling my claim. I can extend the warranty through my credit card company as well, which I might do. The model of my TV is LNT-4661F. |

| From what I read (note that I don't own one) you should probably get all the warranty that you can while it's working. If it did it once there is likely a latent fault waiting to happen again.
Sorry to be the bearer of bad news.  |

| Thanks for all your help Kringle. I just extended my warranty for 2 years. So now what happens? The TV will work perfectly for 2 years and I will have spent another $120 on the thing, haha. Anyhow, I'll keep updated for all of us unlucky enough to have expensive shoddy LCD TV's! |

Pierrefonds, QC | Glad to hear that you're covered. From what I read, $120 is only about 10% of the repair to the LCD screen. Anyway, all the best with that!  |

I had the same thig happen to me after only 2 years on my 40" Samsung LCD. Turns out the the LCD power Supply went out and it's backordered for 4 weeks...gees! Cost to replace (depending on stock) is about $400.00 about $150 for the part and the rest labor |

Update to my previous post:
After several more phone calls and faxes to customer service, it appears Samsung will extend the manufacturer's warranty for 3 months after all. A tech will be coming out to repair the TV.

San Diego, CA | Excellent. That's the only good thing I've heard about them so far! My TV has been working since Sunday of this week (knock on wood). Sad thing is I'm almost afraid to turn it on now. |

| said by Adamd2 :Sad thing is I'm almost afraid to turn it on now. Turn it on LOTS! You want it to break before your two years are up!!! 
You know, for a fact, that it will inevitably cease to function just before "the big game" or whatever it is that you just have to see... |

you will find that the inverter is integrated with the panel and is not a part replaceable by samsung.
you might find one on the 'net however, more than likely it will be from a used set that had physical damage to the panel, we dont use parts from other sets and we are not authorized to do that.
certain, not all LNT/LNS models have problems with the inverters.
if you are having a problem with your set and you call up samsung and "be nice" with the rep on the phone about it (not scream "i wanna new tv !"), they will give you an extra 90 days labor/parts to cover the repair, but this will only work if you are indeed experiencing a problem, as the authorized field engineers do not like travelling perhaps 50-100 miles to your house to service something "just because" (we get this alot from the folks at avsforum.com).
we are not authorized to replace a component that proves not faulty, especially panels.
it also helps to fax over or scan and email your bill of sale (receipt) and any photos/video of the problem as well.
authorized field engineers can obtain any part for any samsung product within 3 days or less unless that part is on backorder which is very rare.
we get priority for parts before the distributors that sell them to non authorized service centers do.
if you PM me the model, serial and version of your unit found on the sticker on the right front side of the unit, i can pull up any information regarding the set (except the customer information).
