I have a Samsung TXN3075, makes great video from laptop or cable input...for about 5 minutes, then its good audio, black video, until it cools down then it will work a bit. Could someone give me a bit of help here?

A Samsung home theatre system can make watching movies at home like going to the theater. Proper setup is essential to get the full benefit of the Samsung system, which is available in 5.1 and 7.1 channel surround sound configurations.
Typically the final step in setting up any home theater is connecting your TV to your system.
Like most home theatre systems, your Samsung home theater receiver will allow you to plug all of your components into it, meaning you only have to run a few cables to connect your television to your system.
Make sure your playback devices are properly connected to your receiver.
Whatever playback devices you use, make sure they are plugged into the appropriate inputs on your receiver.
DVD and Blu-ray players, satellite boxes and cable boxes should all be plugged into video inputs, and CD players should be plugged into audio inputs.
Your receiver will have labels on the back panel indicating into which input you should plug your devices.

Connect the video out to your TV's video input. Make sure you use the correct cable to make the connection. For newer receivers, the connection will likely be either HDMI or component.
If your receiver has an HDMI output, use an HDMI cable to connect the receiver to the HDMI input on your TV.
If your receiver uses a component output, use a component cable to connect your receiver to the component input on your TV.


Connect the audio output of your TV to one of the audio inputs on your Samsung receiver if you want to output your television's audio through your home theatre system.
Most recent TVs will either use an optical cable or a digital coaxial cable to connect to the receiver, allowing you 5.1 channel surround from your television.
If you have an older set, you will likely have to use standard RCA cables.


Turn on your receiver and press the "Setup/Menu" button on your receiver's remote.
When "Input" appears on the display, press the right arrow key on your remote to select TV from the list.


After selecting TV, press the up or down arrow keys on your remote to select the audio input jack into which you have plugged your TV's audio cable.
Press the "Exit" button on your remote to exit the setup menu and lock in the settings.

If you're not an electronics junkie, hooking up your surround sound can seem daunting.
There are so many wires and settings that it's understandable why some people might rather pay someone else to do it for them.
But you can do it yourself as long as you make sure the speakers are positioned correctly; the wires are not only plugged in all the way, but plugged into the right places; and the settings on your television and amplifier are set up correctly.

Check to make sure your surround-sound speakers are correctly installed.
Locate the test function on your surround-sound remote control or amplifier panel to do this.
You will know your speakers are hooked up if sound comes out of each speaker during the test.
Make sure your audio cables are hooked up properly.
Make sure the audio cables running from your television to your amplifier are plugged in correctly. The red and white wires should be plugged into the "Audio Out" spot on the back of your television.
Those same red and white audio wires should be plugged into one of the "Audio Input" spaces on the back of your amplifier.

Turn on your television.
Locate the "Menu" button on either your television remote or your television set.
Scroll through your options until you find "Audio Mode" or a similar naming convention.
Select it.
Scroll through your options until you find "Digital Audio Out," or a similar naming convention. Choose it.
Scroll through your options until you find "Dolby Digital Out." Select that option.
Power your surround-sound system on.
Make sure you have the correct audio input selected.
After the correct audio input is selected, make sure you actually have the Dolby Digital aspect of your surround sound system turned on.
The default for most surround-sound systems is the standard two-channel, stereo output.

• Plug the power cable of the Samsung VHS/DVD player into an available power outlet near the television.

Connect a set of RCA audio and video cables to the color-coded outputs on the back of your Samsung VHS/DVD player. The colors of these cables are yellow (video), white (left audio) and red (right audio).

Take the other end of the RCA audio and video cables and connect them to the color-corresponding inputs on your television. When plugging in these cables, look for a label for the input, such as "Video 1" and "Audio 1." This will be important in Step 5.

Turn on the television and the Samsung VHS/DVD player.

Tune your television to the video input channel that you noted in Step 3. If you did not take note, you can also tune through your television's input channels until you find the one displaying the signal from the DVD/VCR player.

Insert a VHS tape or DVD into the Samsung player and press the "Play" button to verify that the unit is functioning properly.

Component Video

Plug the power cable of the Samsung VHS/DVD player into an available power outlet near the television.

Connect a set of component video cables to the color-coded outputs on the back of your Samsung VHS/DVD player. These cables will look similar to composite audio and video cables, but they are instead color-coded as red, blue and green.

Plug the other end of the component video cables into the color-corresponding inputs on your television. Take note of what input number you are plugging the cords into, as it will be useful later.

Connect a set of RCA audio cables to "Audio Out" jacks on your VHS/DVD player, then connect the other ends to your television. These cables are color-coded as red and white and must be plugged into the same input number as the component video cables.

Turn on the television and the Samsung VHS/DVD player.

Tune your television to the component video input channel where you connected the Samsung VHS/DVD player.

Insert a VHS or DVD into the Samsung player and press the "Play" button to verify that the unit is functioning properly.

There are many methods to do this.
If your cable are ONLY RED,WHITE,YELLOW
1 Plug the red white and yellow cables to there corrosponding jacks on your DVD player
2 Plug the red white and yellow cables to jacks labled video IN, Audio IN. They will be colored on the back of your Tv
3 Plug in the power cable.
4 Turn it on and flip through the inputs on your tv until you see the picture
IF your cables are RED, GREEN, BLUE, RED, AND WHITE
1 Your are using what is called conponent video. This is a high definition video.
2 Three of your plugs are for video. They are Red(Cr) Green(Y) and Blue(Cb)
3 Plug the GREEN into the Y jack
4 Plug the RED into the Cr jack
5 Plug the BLUE into the Cb jack
6 Plug your power cable int o the wall if you havent alredy done so
7 Plug the other red cable into the audio right jack
8 Plug the white cable into the audio left jack
9 Turn it on and surf through the input until you find it
If you have a BLACK, RED and WHITE
Do the same as RED WHITE and YELLOW but
1 Put the black cable into the s-video slot
2 Surf through the inputs until you find the picture
If you have ONE BLACK CABLE
1 This is called HDMI(High-definition multimedia interface)
2 Plug one end into the tv and the other inte you dvd

Thank you for your time, Good luck and I hope this works

We just experienced the same failure - did you ever find a resolution?

Maybe the problem is not from cables but from HDMI hole/jack, rusted or something

Hi, You will need to go into the menu of the AVR to change a few settings. To get into the menu -

1. Make sure you are on an input of the TV that is connected to the COMPONENT VIDEO output of the AVR (I imagine you already have this hooked up)
2. Using the Denon remote that came with the 1907, filp it to the back side and open the door that covers more buttons.
3. Press the System Setup button
4. Go into the AUDIO SETUP
   
5. Make sure the DIGITAL INPUT ASSIGNED is set to none for the audio input you wish to use for the PS3.
6. Going back a menu to VIDEO SETUP, make sure that the COMPONENT VIDEO you are using is assigned to the AUDIO INPUT you are using.

That should fix your problem. If you need more clarification or this did not work feel free to post that on this question. Good Luck

I think your cable box is old version together with weak signal caused this problem. I guess you are using coaxial cable hooked up to the TV at TV cable input jack.
At the TV there are some better quality inputs which are real digital transmission (audio and video) HDMI and components (digital video and analog audio).
The most simple and best quality is HDMI provided the box has HDMI output.
Secondly is component inputs. There are 5 cable trends in which 3 of them (red, blue, green) for video and the rest 2 are for audio (red , white). The cable box should have same color accordingly as ouput. Please note that the color must be matched otherwise you will see the screen has one color only.
Playing a DVD player to see picture good or not. If picture is good, TV has no problem at all.

Good Day;
The best picture you can get ryanvo2 depends on the use of the TV's input capabilities. It also depends on the games outputs.
In today's world of electronics there are more options than in the past, so it depends on the age of your equipment.
So, let's look at the most five (5) options available; number (1)one being the worst and (5) five being the best:
1.) RF, radio frequency, direct cable or antenna input.
2.) Video input; yellow, red and white cables.
3.) S-Video input, some units may require additional audio cables.
4.) Composite Video, red, green & blue cables.
5.) THE BEST 'HDMI' cable, computer type.
ryanvo2 I hope this was helpful. I hope you have years of game playing enjoyment in front of you.
Good Luck, Big Irish

This definitely sounds like a circuit board-level issue. Have you tried moving to a different input set (i.e. if you're now on the TV inputs, try the DVD or AUX inputs for both video and sound)? Just to rule out the obvious, have you made sure that it's the receiver and not the DVD player? I know that you said you powered down the receiver, but if you had turned it off by pulling the plug on the surge suppressor and your DVD player is in the same suppressor, you might want to make sure it's the receiver and not the DVD player.

If you're sure that it's the receiver, then you might want to look into taking it to a Pioneer service center to have it repaired. If it's not worth the cost to you, it might be time to be looking into a new receiver.
