When I turn our tv on the power light comes on but the screen is still black and there is no sound.
Black Screen - Sometimes, the TV may display a black screen, now you need to check the cables whether they are properly plugged or not. Reconnecting all the cables can also work for this problem. Also, if the screen has a screen saver, check how it's set up. And, if nothing works for this issue, then there is a possibility that the lamp, rear projection, or the LCD panel may have been damaged. Now, you need to check your warranty card of your television and se your set comes under the manufacturer's warranty period. Call the customer service for technical problem and get replaced if a part demands it.
consigning no sound on your TV
You might need to do some troubleshooting tips first before calling arepair man to replace the sound IC inside the TV.
Check the volume setting. It might sound simple, but it's the best place to start. Make sure the television sound is not muted or turned all the way down using the remote or buttons on the front of the television. If the batteries are dead in the remote and the TV is muted or turned down, it might seem like the sound is broken.
Examine cables connected to the TV. Sometimes a loose connection can cause a loss of sound. Ensure all cables are tightly connected to the television and correctly inserted. Some peripherals are connected using a three-plug system and are usually labeled red, white (sometimes black) and yellow. Both the red and white leads are sound cables. Try removing all the cables (except the power) from the back of the television and turning it to TV mode, then listen for static or other sound.
Plug in headphones to the television with all cables re-attached. See if you can hear sound through the headphones. If you can, it may indicate that the TV's internal speakers are not working. If you can't hear anything through the headphones, it may be indicative of a larger problem.
Call a repairman. If at this point everything has failed to produce a sound, it's time to call in the professionals. A qualified technician should be able to fix the problem either at your home or in a workshop.
