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.

No picture


Sounds like you have a backlight problem. To verify this, turn on the set, dim the lights in the room, and shine a bright flashlight on the screen. If you see a faint picture you have a backlight fault. It could be as simple as a bad capacitor in the power supply, or a faulty inverter board, or in rare cases a bad backlamp.

I have a RCA L32HD31YX12 TV. The TV works fine for a half hour and then the screen flickers and goes black. The sound continues. If I turn the set off for a half hour, it works again for another half


You have answered your own question, someone needs to open it and find a loose plug or broken solder connection--if it reacts to being tapped on that is the issue- a physical problem inside.

Tv has no picture but sound is ok


First of all, change the input device to something you know works for sure. Look for any jammed buttons on remote or on control panel. (This can happen, if you inadvertently sit on the remote hidden under a magazine or newspaper) Check the picture settings to ensure that these are ok. If problem persists, it might need attention by a qualified service technician.

I BELIEVE THE ISSUE IS THE RESOLUTION THAT THE VIDEO CARD IS SET AT. IF YOU ARE USING THE SAME RESOLUTION AS THE PC, IT WON'T WORK.

TRY SETTING THE VIDEO CARD RESOLUTION AT 1920 X 1080. THIS SHOULD WORK.

It was working fine then no picture dark sceen sound work fine


More information is required. Your backlight is lit (screen not dark) but I need to know what you have connected to the TV (your sources) and how they are connected. Does the menu/OSD (on screen display) work?

TV picture flickers


If your DVD player is separate from your tv, you might have a loose cable plug or connection. Depending on the type of flicker you have, a vertical circuit loose connection would cause this. If you could connect it to a cable or antenna it might tell you where the problem is located. A faulty circuit in the DVD might cause this too. Stargazer

Tv has sound but no picture


Sounds like you have lost video somewhere in the video circuits. Possibly the picture tube could have gone bad or lost filiament voltage. You can check to see if you have high voltage by holding your bare arm close to the screen. The hairs will stand up if you have high voltage. Absence of high voltage will also cause a black screen,but the sound might not work either since on some sets the power for the sound is supplied from the same circuit as the high voltage. Stargazer

Flickering Picture?


Your set might have a high voltage leak and that is the noise you hear when is showing the screen problem or even maybe an arking too ,either one is related to the high voltage and it can be dangerous,if you are familiar with tv service you can try to see where is arking and replace the part with an exact replacement but if the set has a leak you will not see it and is not safe to be close to it,if you are not too familiar be safe and call for assistance from a servicer.
