Question about Samsung TXN2745FP 27" TV

Black Screen, but menu shows up

I am having this problem on this tv I just got used, its like it is not getting any a/v input. the screen is just black, no snow, nothing, except the on screen menus seem to work fine. i have tried all a/v (but not component), and cable to no avail. sound gets louder and softer, but is snow only, not what is coming in. i've checked the input (a/v / cable, etc) and channels, they are correct, but nothing. no remote. I own a pawnshop and all my other tv's work from the same input, so thats not it. supposedly my employee that took it in tested it, but who knows. thankfully i've only got $60 into it, but is it worth fixing or calling a repairman? thanks!

    ...addtionally, there was no warning signs, this is all i've seen it do. it also makes a louder than normal noise at powerup (something i would expect to hear from an older tv). thanks!

If you are sure that it is connected right and tested the audio inputs because to do that you will need an original remote, then you have a bad tuner or input switcher IC and no I am afraid that the TV most likly is not worth fixing. Good Luck

    that noise when the set starts up is normal. That is the automatic degausing circuit activating

If my tv show a black screen and nothing els and nothing els what is whats the problem ?

Black Screen,
I think there are 4 possibilities for your problem. In order:
1. Is this a configuration issue with the set? Do you have the proper input selected? Did the grand-kids help you by re-configuring your set with random remote commands? Can you issue commands through the remote and get reasonable responses from the TV? A black screen could just be an incorrect signal source selected by the remote.
2. Does the set have power? i.e. does the little light on the set come on when you turn it on? Be sure to test the AC line power to make sure the breaker has not tripped. You will get nowhere without power. If the set has power, then;
3. Is there a video signal? Is the cable or satellite box (if you have one attached) Live? That is, does it's little light come on ? Again, gotta have power to work.
Cycling through the possible sources on the TV, one source should be over the air broadcast. Antenna or not, you should see snow on the screen when on this source, indicating that the set is trying to display something, it just has nothing to display. If you see snow, you can be pretty sure the set is working and you need to track down why there is no signal.
4. If you have power and signal, and you still have black on the screen, you may have an internal problem in the set. A good test would be to borrow a TV set from a friend and swap out your set. If your friend's set works, you have a TV problem. If it doesn't, your set is probably fine and you need to look elsewhere. Note that a working friend's set rules out problems everywhere except your TV set.
You should try to correlate when this problem started with external events. Did you have a lightning storm? Spilled a drink? Sit on the remote? What happened (if anything) just before the set quit working?
If you have a problem with the set, I am not qualified to advise you on the repair, nor should you attempt it. There are serious voltages present in all TV sets, and you could DIE!
Take the set to a qualified service tech. and have them repair it, or take the modern route and recycle it before buying a new replacement.

Trying to set up my xbox to my orion tv but cant get it to work. the screen shows nothing but snow

You have to switch the TV to the proper input. If you are getting snow, the tv is on the cable input. Xbox only works on the composite or component inputs on the set. The inputs are labeled at the jacks that you have connected too. Find the input button on the tv remote and switch the tv input to the input number you are connected to. Thanks for using fixya.

Are you connected to cable TV or an outdoor antenna? If on cable TV check the signal on another TV or if on an outdoor antenna you will need a digital TV adaptor to pick up local stations due to them not being available in analog anymore. Please take moment to rate my answer. Thanks...

Power on tv and I get black screen with sound.

You have lost the input will have to go to Setup/Net Command and set your input to the one with signal (either a TV input or a Component input). If it is reset...the input likely switched to a non-usable input

My tv get snow when i try to play a game

Try using another TV. If you don't get the same problem then it's the TV and not the PS3. You might also want to try changing the display settings so that you're using the correct outputs.

Can not access menu or input functions

Hi rduncan27,
I will be happy to help. 88% of LCD tv problems are with the backlight, the symptoms you described indicate a probable inverter malfunction. Lets do a simple test to check the functionality.
  1. Get the tv to a point that it is producing sound.
  2. Take a flashlight and shine it on the screen.
  3. Look very closely for a dark video image.
Let me know your findings and we can proceed from there.

Btw, I’m available to help over the phone in case u need at

it's probably the Time Warner cable box that have issue and not the TV. Try using a DVD player and test the same input, it should work fine.
