What to do when television sound doesn't match the picture.

Sounds like your power supply. ElectroRepairShop has one that may match. INSIGNIA NSLCD32F PSM210 417A POWER SUPPLY

Your video cable is not plugged into the matching input to your audio. (ex. audio is on input 1 and your video is on input 2) Once they are matched make sure you television input is matched to where you have them plugged in.

Some cable service providers have a delay in video and audio. It is most likely an issue with your service rpovider. There is a delay in the video or audio. This is not uncommon with some channels.

does the lamp works or not?. if still doesn't work check the ballast. does your tv with sound just let me know.

There is a power supply failure and this might need attention of a qualified service technician

Go to the menu, to the audiio section and see if speakers on/off is selected.

Have you try watching using a DVD player on your t.v if doesn't try watch on it using a DVD player but if still it doesn't have a picture but only sound perhaps there is a problem with your HDTV.

Sounds like you have a convergence problem. If you go into the setup menu of your TV, there should be some settings to adjust the red, green and blue hues and re-position them so each color matches up. If this does not work or if you don't have a menu, your TV *might* have a circuit board with several plastic screws on it. These adjust the picture and it's a very tedious task to re-align each hue correctly.

My projection TV is an older model from 1995, which is probably why it has this circuit board in place of a convergence menu built into the TV.

If adjusting the convergence still doesn't work, you might need to purchase a new convergence chip.

check color code cables be sure all cable match up with the right inputs red to red and white to white rca or HDMI will same you alot of problems but sure that your tv have HDMI outputs

I have a hdtv hooked up with a virgin v+ box but slight delay Why?
