How do you tune


The user's guide and other documentation for the KLV-40U100M are available from Sony here: http://esupport.sony.com/US/p/model-home.pl?mdl=KLV40U100M&LOC=3#/manualsTab . This TV doesn't have a tuner. You need to use a set top box to watch any OTA or cable channel.

I wish that I had better news for you. If you need to adjust picture or the resolution, please add a comment with the signal source for your TV. If the source is a PC, make sure to that the TV is on and set to the correct input before turning on the computer.

Sony KDL-V32XBR1 Displays only snowy picture


Here are a few more troubleshooting steps you can try when your TV picture is just snow. I see that you have already rebooted your TV, but did you turn your set-top box off and on, too?

1. Does the picture show when you play a DVD?
2. Check all of the connections between the TV, outlet and set-top box and make sure everything is secured.
3. Is your TV set to the correct channel (typically 3, but in some areas 2 or 4)?
4. Press any key on the remote to see if the correct mode lights up. (Ex: if you have cable, the cable button should light up). If it doesn't, press the correct mode's button to regain control and change channels.
5. Call your service provider and make sure it's not an overall service outage.
6. Do you have sound but no picture? If so, it could mean a backlight failure.

For more suggestions, see TV black screen or snowy screen for troubleshooting and solutions. I hope this helps!

My tv turns but it doesn't show a picture but you can still hear


If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

Vizio vt420m comes on then flickers and then doesn't show any picture, but the tv stays on


If you have not been using the TV for quite sometime, moisture would have developed some defects inside the TV when you switched on. Sometimes even insects and lizards might get in and cause short circuits. Anyhow this might require attention by a qualified service technician.

Our picture will only show reds and greens, no other colors.


Go to your On Screen Menu to picture settings and reset and choose "reset picture" mode. This will bring you back to factory defaults. If this doesn't work shut off wait 10 sec. and turn on the TV. If still no luck call your best friend who is a TV repairman, you probably have a damaged blue drive.
