Your TV has a headphone jack. This can be used to connect it to a receiver or audio amp to drive external speakers or it can be directly hooked up to a powered speaker.

This sounds like the back-lights have quit working. This is made up with an inverter (ballast) and fluorescent lamps. I want you to try something. In a very dark room turn the tv on and watch what happens to the screen. There is three things that can happen. first the screen will stay completely black. This means the inverter never fired, and this is usually a failed inverter, but sometimes the power supply may fail. there is also a rare time the main module never outputted the signal to activate the inverter, but this is rare because you can hear the audio. So obviously the main is working at least 90%. The second thing that can happen is the screen will light for a split second then go black. This usually means that you have a bad lamp. These lamps are physically locate inside the LCD panel, and the replacement cost exceeds the price of a new unit. You may even see a dark area in the screen. The slight glow will not be uniformly lit through out the screen. Finally the last thing you may see is the screen has a slight glow. This means the back-lights work, but the video portion isn't showing. This usually means the driver board (T-con) has failed. This is probably not available separately, so you must replace the panel to fix it. And like before, the replacement cost exceeds the price of a new unit. One more thing to do when the set is on and in the very dark room if the screen is black, point a very intense flashlight into the screen. Put the flashlight against the lcd screen and see that you have video moving around the glow of the flashlight.

there could be numerous problems, you would need to get the set diagnosed. The bad thing is that the cost to diagnose would be more than what the TV is worth !

Check the picture settings like brightness, sharpness, contrast and color. Change input device to something you know works for sure. Look for any loose contacts in RC jacks. If problem persists, it might need attention by a qualified service technician.

The chroma and luminance section circuits to your tV should be checked. It is very skilled work. The video output section also might to be troubleshooted. I do not think that you can do this by yoursef at home, as sophisticated measuring tools, and sound kowledge in electoronics to do this. If you have all said above, try to repair it. Download its service manual from internet, and begin the work.
