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.

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.

HP Pavilion g series g7 black screen but occasion flicker shows it is up and running.


Hook a spare monitor to the video output usually on the back, if picture is okay! the problem lies in the inverter board, "just below the screen" or the backlight behind the LCD display, or the video cable from the screen to the motherboard has come loose from the plugin. But if both show the same symptom it means the Video Graphics Card is defective, normally built into the motherboard.

I have a sanyoclt2054 picture flickers and then goes black and the sound is ok. what is wrong with this?


Hello,

It is the lamp that is getting faulty, that is why you are having the flickers and the black screen.

when it is completely bad, you will be experiencing a total black screen but the sound will still be functioning.

Have the lamp replaced and the television will be okay once again.

Take care and good luck

Display IC seems to have gone. It will be a replaceable module. Only you have to figure out which one it is. Such thing happen in electronics. Look for any burnt or bulged IC.

Mitshubishi VS-6041 No picture, sound ok


It has been my experience with that model mitsubishi that the usual culprit is loss of vertical sweep. If the beams in the picture tubes stops moving up and down this is detected by the micro processor and the video is blanked, but the set is not shut down. The usual cause of loss of vertical sweep is bad solder connections on the deflection yokes or a failed vertical output IC.

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 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
