Sound is working on the tv but the picture isn't

Need the model number of the set and also if any lights on the TV come on or blink when the picture goes out or not.

ya know I hate to say it but I've done this before. check the mute button on your remote. I've accidently hit mine before and it took me several days to realize it. lol. if it's not that. check the volume of the set itself, then check the volume with the remote....I know these are weird things to check, but they do & have happened, to me. lol. good luck & God bless.

Replace the main board. That board controls all the symptoms you're having. You can get the Vizo Main Board 3642-0182-0150 thats the board for your model from www.tvcircuitboards.com it has a 6 month warranty

Try a factory reset:

1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote)
2. Using the other hand, press the Power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and Enter.
5. Power off and reboot the TV and Computer.
6. Run channel auto-scan to regain the picture.

Hi David:
If you can check menu settings there, isn't the LCD screenviewer issue; then sound like a malfunctioning CCD (Charge Coupled Device) image sensor... in both cases (LCD or CCD) this isn't a job that you could solve yourself; this wrong include distorted images or abnormal colors, scratchy purple lines, blank or black pictures, and/or black videos with good sound being recorded on the camera's flash card.

I suggest check this link for additional details in this previous solutions for an Defective CCD and next contact your Canon service. I strongly suggest (taking into consideration the age of your camera) to evaluate the cost of repair versus the cost of a new camera with similar features, before making a final desicion.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Could be a problem with the LCD viewer screen, or, if not, could be the CCD image sensor go to bad; in both cases this isn't a job that you could solve yourself; this wrong include distorted images or abnormal colors, scratchy purple lines, blank or black pictures, and/or black videos with good sound being recorded on the camera's flash card.

Hope this helps.

The problem is usually from the power or the Y sustain at the left or right side of the display when one of the large capacitor or heat sync on the capacitor even the flat power cable connection it to a main power board needs to be checked too, if the fuses on the board are blown it will need to be replaced

But after replacingthe fuses and the capacitors and still no solution,youwill need to replace the all board ..

You can also trouble shoot first before going to the board of the TV..

How to Troubleshoot an LCD With Sound But No Picture


It can be overwhelmingly frustrating when an electronic device as expensive as an LCD television set starts having problems. Luckily many of these problems are easily troubleshot. While being able to hear sound coming from your LCD television but seeing no picture may seem serious on the surface, fixing the problem involves checking a few different settings to make sure everything is set properly


Instructions



Check the video connection of any devices plugged into the LCD television. If you can hear sound but are seeing no picture while trying to use something like a DVD player or cable box, the problem is probably that a wire is loose somewhere. Check the yellow video cables running from the DVD player to the TV and make sure everything is plugged in firmly and where it should be. Also check the coaxial cable running from the cable box (or cable outlet) to the television and make sure that wire is also screwed in securely.

Check the image settings on your television and make sure everything is set properly. Certain settings like "Picture" or "Brightness," if set to one extreme, can make the picture appear completely black. This could cause you to simply hear television shows but not be able to see them. Reset all picture settings on the TV to their original factory default settings to see if that fixes the problem.


Try another channel. If you're watching TV and not getting a picture, the first thing you should do is check a variety of random channels to make sure it is a problem with your TV and not with your television signal. If it is a problem with the television signal it is the fault of the TV station or cable service provider and there isn't anything you can do yourself to fix it.


Try the DVD on another DVD player. If you're trying to play a DVD and can't see any images, make sure the disc isn't defective. Try it on another DVD player or a computer DVD drive and make sure the disc works in the first place.

Hope it helped ..

Go to your menu and choose picture. See if your settings are normal or if the brightness is turned down. If it isn't then it's a problem with the T.V.
