Sound no picture

When you're asking for help online, it's a good idea to provide more information. It's really hard to determine the problem without seeing the set, so tell us anything you can. Some information that may be helpful:
1) Make/model of the failing part
2) What's connected to it?
3) When did you first notice the problem? What were you doing right before the problem struck?
4) Have you seen any error messages?
5) Is the problem constant or intermittent?
6) Be specific about what you observe. In this case: Does "no picture" mean the screen is dead, or that it goes from that deep "off" black to the slightly lit black that you get when the screen is on but getting no input? Does the screen flicker? If you do something to change the input, does the screen react in any way? Is the sound normal? Do you hear anything unusual? Does the set smell OK? Feel around; is anything unusually warm?

Some troubleshooting steps to try:
1) Turn it off, then back on
2) Check cable connections; turn it off, and unplug then replug every cable coming out of it, then turn it on
3) Turn it off, disconnect anything that it's connected to, then turn it on
4) Turn it off, unplug it for a few minutes, push and hold in the power button for 30 seconds, then plug it in and turn it on
5) Swap out any cables you can
6) Swap out any accessories you can (verify that peripherals are working); in this case, what is supposed to be supplying the picture to the TV? An internal tuner? External antenna? Cable box? DVD player? If you can, take those devices to a working TV to see if they work if connected to another TV.

Give us any further info you can, including whether any of the troubleshooting steps had any effect.

Fpe1906dv picture but no sound

Hi Ted,

This kind of symptoms indicated of fault either the internal speakers or the earphone jack itself. To isolate where the fault came from, the speaker's resistance inside the set needs to check using the multimeter/ohmmeter.
Watch the video below to give you an idea how to test the speakers.

If the speakers are in good condition, then the fault came from the earphone jack itself. It has a built-in switch that will open/closed once you plug in your headset to cut the sound coming to the internal speakers of the TV and hear the sound only to your headset. The problem is, if the contact stuck or dirty, the sound will not pass through the speakers. You have to spray it with electrical contact cleaner while inserting and pulling the headset plug to clean the contact.

Hope I helped you.
Have a nice day!

I was just watching TV last night and the screen just turned black, but I could still hear the audio from the show I was watching. I can't seem to get a picture from this TV at all. Any ideas?

If you have sound and no picture if might be a bad CCFL backlight lamp. On a Sharp LC-32SB23U it has 10 lamps in it and if one burns out it will have sound and no picture till you replace the bad lamp. You did not said what make and model flat panel tv you have.

Sony Wega 32"TV - noise on startup

The slight flash on the screen is usually because the CRT (picture tube) is holding a better than average charge and this is what we call "pre-glow" The noise that you hear, is that everytime you turn it on or just after it has been off for a while? If only after the set has been sitting off for a while then your noise is the internal degauser for the CRT and that noise is 100% normal. The degausers in Sony TV's are so strong they usually make the plastic cabinet vibrate a bit.
