Tip & How-To about Vizio L32 32 in. LCD HDTV

My TV picture has a greenish tint.



The first thing to check is the cables connected at the back of the TV.

Check cable connection, and try using a different cable, video signal is often coded in separate colors signal, and a bad cable can cause a green picture when red or magenta (depending on type of signal) are out.

A faulty receiver or DVD player can also send a bad output. Try connecting different devices to TV.

If the cables and receiver are OK there are also internal faults that can cause the same effect.
The fault depends mainly on the model and type of the TV set.

On all TVs a faulty input/output can cause greenish picture.

On all digital TVs the signal is also elaborated on different color channels . Video circuits are often located on digital board.
A fault on digital video processing can cause a green picture.

If you have a rear projection CRT based technology, one of the three CRT may be faulty, or the power board supplying the CRT (red in your case) may have blown.
In that case you will get a greenish picture.

If instead you have a CRT TV, a greenish picture means that the red gun inside the cathode ray tube is not working. The CRT itself must be replaced.

Generally, when the problem is not the video cable , or the connected device, the TV must be inspected and repaired by a technician.

If you have a new digital TV, as an LCD, Plasma, or any non CRT based technology, the problem is usually caused by cables, input output, or connected devices.

Check the cables thoroughly, if that is not the problem, call manufacturer to find the nearest repair service location.

there is no signal on my emerson tv, how do i get one


1. You are not on the right input for the signaling device: Verify which input number (or type ie HDMI/component/video/Cable) your device is connecting to and tune to that input.
2. The signaling device is not powered on. Verify it is on and the cable is properly seated into device and TV.
3. The cable is bad. Try a different cable or use alternate type of connection.
4. The specific input port on the TV is bad. Move the connecting cable to a different port (ie from HDMI 1 to HDMI 2) and tune the TV to that input.
If you are using an Over the Air signal (OTA) with rabbit ears or and antenna use the TV menu to run an auto tuning scan of your local stations.
If you are using a tuning box (cable/satellite) over a coaxial connection check connections and tune the TV to CH 3 or CH 4 and check for picture. There may be a switch on the back of the box indicating CH 3 or CH 4.

Television say check signal cable . I have a scientific atlanta cable box.What do I do?


How is the TV connected to the cable box (HDMI, component video, etc.)? Make sure that the cables are securely connected and that the TV is on the correct input. Try swapping the current cables for new ones. (The HDMI cable has come loose on my entertainment system at times.) If you route HDMI cables via a sound receiver (cable box -> receiver -> TV), try a direct connection to the TV.

For my TV, I have to turn on one set-top box before I turn on the TV to get the signals to correctly synchronize. (Try turning off everything connected to the TV and then turn on the accessories first. Then turn on the TV.) For another set-top box, it needs to be turned on before the TV. (So try both options.)

Make sure that your set-top box is on and try a different TV or input if possible. If a second TV doesn't work with the box, contact the provider and check for a service outage. (Also try a different set-top box (like a blu-ray player) to check if it is the input on the TV.)

Note: I've had mice or other things damage wiring; this takes out the cable and phone lines. If this is outside damage, your service provider should repair the damage for free.

I hope this helps. Please add a comment with more information about your TV and the connections that you are using for additional support.

My dvd player appears to be working - the disk is in place and the numbers advance as if it is playing - but all the tv screen displays is No Signal. I've talked to a Comcast tech and the problem doesn't seem to be with Comcast. I've checked to see that all the cables are tightly connected. Any other suggestions?


Make sure your TV input source selector is set to the correct option (Video 1, Video 2 or Rear Video Connection or whaever the options are for your TV) when you want to play a DVD.

Try using the DVD player on a different TV to see if the DVD player is working OK.

Then try a different DVD player hooked up to your TV to see if your TV is set up OK.

You can also try using a different set of cables just in case the cables are faulty.

Try using an S-Video cable from your DVD player to your TV (if they both have those connections)and see if you get any signal that way.

When you are testing, be sure to check the sound on your TV to see if you are getting any audio signal from your DVD player.

By carrying out these troubleshooting procedures you should be able to narrow down exactly where the problem is and then fix it.

can't connect to pc


How are you trying to connect to the PC? Does your video card support TV-out?

If you are trying to connect VGA to component video, you need a converter like this: http://www.svideo.com/pctocomponent.html . There are similar ones for PC to composite video. The VGA to component video cables will not work since the two signal formats are different.

Some video cards do have a TV-out option, you will need to read the documentation to set up that option. (Those cards come with a special dongle to connect the card to the TV cable.)

If you have the converter and are not getting the signal to the TV, first check that the computer video is set to use the external monitor. (This may need to be enabled in the BIOS.) Next check that the converter is working. (Try connecting to a different TV or this TV to another computer.) Try different cables and make sure that they are fully seated to all three devices. Replace the converter if you find that it has failed. (If it is under warranty, send it to the manufacturer.)

I hope this helps.
