Re: No video

Can you still see the menu? if not your problem is either the power supply or the y-sustain. check the va and vs from the power supply. the voltages are listed on the back of the panel on a grey sticker. if you have these voltages then replace the y-sus

Scren went blank. We have sound but no picture .what do we neen to do to get pictute?

How is your TV receiving video? Are all cables connected? With RCA (the red, yellow, white ended cables) the yellow is the video, the white and red are left and right stereo sound. Ensure that all cables are connected into the correct spot on the back of the TV and that you are on the right input (Video 1, AV1, etc).

Firstly, CAN??, and then how do I get an NEC NLT-19XT1 television to work with a TEAC High Definition Digital Receiver HDB848 HDMI, please. Anyone know how? Appreciate all the help I can get. Thank

Id the TV Anolog or Digital? If it is analog, then the digital receiver must have RCA outputs to meet the TV's RCA inputs. To make an old analog TV work (meaning getting a picture), you have to check id the receiver has RCA or S-Video outputs. If so, then connect an RCA cable with yellow into yellow, red into red and white into white and then connect the same colors plugs to the yellow, red and white to the RCA inputs of the TV. Or, you can connect a S-Video cable plugs in the output of the receiver and the input of the TV, disconnect the yellow RCA plugs at both the receiver and TV sockets and leave the red and white cable for sound only, as S-Video has an improved video signal, therefore better picture quality. On the TV you have to select an AV input channel, like AV1 or AV2, etc. The same channels that you had used when you were once watching VCR tapes on analog TV. Hope this helps.

My green light comes on but no picture

Sounds like tv is on wrong input. Be sure HDMI wire or cable input is connected to tv. Look at which input it is on. ( like HDMI 1. Or cable etc. take tv remote (with cable box on ) press input / video button and arrow down to different inputs ( slowly ) until the right input is detected or simply go to the right input you noticed the cable was connected to. Different inputs are there for different sources of connections like DVD. Games. Etc. each work like its own tv channel. Good luck.most times this happens when you are watching tv and press the TV. channel button which will take you to a different tv mode

How do I hook up my surround sound system thru my stereo and tv

connecting your surround sound system is not complicated.things you may need:OLDER STEREO SURROUND SOUND:analog red, white, and yellow cable connectorsHDMIaudio fiber opticsif you bought your stuff new from electronics store,then it would be easier.all you need is HDMI cables (mostly)depending where your inputs and outputs go, you must know the rule. OUT-TO-IN. that means if you are using a cable box, dvd, bluray, playstation, or xbox. everything in these electronic devices are OUT. then connect them to the IN ports of your surround sound. at the back of your surround sound there will be connections saying IN-dvd, IN-dvr etc. connect your OUT DEVICES.
now from your surround sound to your tv.the same ruleout to in of your tv. You should look for HDMI port that is saying OUT. you will connect your HDMI cable from there connecting to your IN of your tv. remember which port you plugged the HDMI cable as you will switch to that particular input. it will say at the back of your tv in-1, in-2, in-3 or as much as the manufacturer want to have in there product.
connecting your must remember the color code.if you chose red as positive, all the red wire must be positive.colour may be different but same idea. if you have sub-woofer it will be an analog cable you will only use single cable. At the back of your surround sound there's a connection saying sub-woofer out.
now selecting your inputs.turn on your tv and stereo.newer tvs and stereos are smart they can configure there system which is turned on.
anyways if you will do it manually, you must select from the remote what is the connected input. (input 1, input 2 etc.) if you found the right input, do the players (dvr, cable box, dvd, bluray, playstation, xbox etc) turn them all on and select from your stereo remote control.note all the inputs you selected.

I have an onn 42 inck flatscreen tv and since last night have lost all colour on screen,,,tried cable and scart all seem ok,,any ideas


If the problem happens using different input and devices, then it is either the terminal circuit (input/output connectors) or the processing unit in main board. The terminals are unlikely the culprit if problem concerns different inputs.

I imagine that the picture is not properly B&W (gray-shades) but some kind of reddish, bluish or greenish picture as the LCD will process picture using RGB (red green blue) channels instead of CYMK (cyan yellow magenta black) like CRT TVs.

Test the TV using an external aerial. You will notice if the channels have the wrong color even from static.

Use different inputs, different cables and different devices. beware of SCART cables, the SCART contacts are very easy to break. A defective cable will loose picture. Better testing using AV cables and component cables. AV cables are red/white for sound and yellow for video. If the two-wired yellow cable does not work, then the TV is faulty.
Other test can be done using component cables. Component cables send the three red-green-blue signals on different cables, hence testing is simple. Test swapping cables and see if TV tone stays the same if color tone changes the problem were the cables. Test also using at least two different devices (e.g. one DVD player and one TV receiver or a playstation).

If you find that the TV is defective call the manufacturer at the number listed on manual. If the problem is that one or more RGB channels do not work the TV main controller board must be replaced.

Trying to hook up a dvd and wii with direct tv and can"t get sound out of wii! HELP Can you show me where to plug cords in?

Your TV has two sets of AV inputs. One on the side and one at the back. The Wii has a 3RCA cable ( Yellow / Red & White ) . Connect these jacks to the corresponding color sockets on the side input of your TV. Select that input on the TV and your Wii sound and picture should come on.
For the DVD player you have to get a 5 RCA component cable. This cable will have 5 colored jacks, connect the White & Red to the Audio in of the TV and then connect the Red/Blue/Green jacks to the component video input of the TV.Do the same at the DVD's end also. Setect that source on the TV and you should hear the DVD sound and picture.bobhifi_31.jpg

I have a great picture but no sound. What can I do?

There is more than one thing to try. First make sure you have sound cables attached and if so that they are attached to the right spot on the television. Coming from a cable box, dvd player, and etc. the red and white audio cables should be attached to the same input input input input (did I just say input) as the video cables. That is normally the problem when I am supporting people--they normally connect the sound cables to the television's output.

The second problem is usually that there are no sound cables attached. If you are using component cables you should have a total of five green blue red white red attached.

The third problem is usually that an hdmi cable is going between the cable box and the television and the cable box is not set for audio output hdmi. Please check the settings in your device.

The fourth problem is usually that the cables themselves need to be replaced.

The fifth problem is usually the television is in sap but that would only be relevant if you are using the television's tuner, and only a few channels wouldn't have any sound.

Sixth and most unlikely is that the television needs a sound board/repair.

No sound on play back using camcorder on technika tv

Looks like you are using Component cables. There are five cables. The first three cables are Green,Blue and Red. These are the ones that are molded next to each other and are the Video signal cables. The other two cables are Red and White and they are the audio cables.
First to correctly hook up these cables you need to Connect (Match) Color for Color. (Green to Green, Blue to Blue, and Red to Red. To tell if you have correctly connected the Video cables is to look at the screen. If the picture looks ok (Normal with no colors missing then you have connected the video cables correctly). If you see a missing color meaning red, then switch the Red cables. The picture should be ok now. The remaining two cables are the Red and White cables. The "Red cable" is for the "Right" audio input and the "White" cable is for the "Left" audio Input". If all is connected correctly then you should have a good picture and Left and Right audio.

NO volume

often people make the mistake of hooking their devices to the tv using more than one input.  a cable box for example may have many different types of outputs but you are only going to use one to the tv (preferrably the highest quality connection). try switching the inputs on the tv to see if you get the same picture on two different inputs.   If using s-video, you will also need a red & white RCA cable for audio.  The order of video cable quality from lowest to highest is this: Coax(screw on), Composite(yellow,red,white), S-video(Round)+(red,white), Component(video=red,green,blue), HDMI(carries HD video & sound)
