Picture does not come on, only sound

Our LCD TV Model # 37LC2D is cable connected and we get the sound for each station but the picture does not always come up. It sometimes will come on within 5-10 minutes but at the moment it has not come on even if we leave it on for half an hour. We sent it back to the repair place once and they said it was repaired but after two days of working fine, the picture started not coming on again.

SOURCE: Component Video inputs do not work

I started back in the day of tubes. A family would have one set and it would be a 19" black and white. There are different resolutions now. The components probably do work, but, they don't pass the 480i signal. The satelite converter's analog signal needs to be set to 480p and the DVD needs to be set to progressive if it does have that setting. If the DVD is not a progressive scan DVD, then, the only inputs that it will show on is the analog signal. Some of the dish converters have a switch on the face for changing the resolution. If yours doesn't then put it in an analog source and go to the menu and change it there. Then move it to the component input. Hope this helps.

SOURCE: My TV pictures turns black afetr a few hours but I still can hear sound perfectly!!!

It sounds like your rptv lamp is going out. If this is an older DLP this is most likely the cause. You can get a replacement at www.laptopsforless.com part number BP96-00224J for $151. If the tv is still under warranty, I would have them do it, otherwise replace it yourself. If so here is a link to give you step by step instruction. Please give me a good rating. ;-)

SOURCE: TV picture goes out after 10 minutes of viewing with popping sound

It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.
Thanks,
Lee

Rear projection hdtv, most likely damaged tubes. Don't repair this by your self get a tv repair man to do it before you injure your self.

SOURCE: Sharp aquos lcd screen goes blank

i was having these same problems with the screen going black, and i found that when i hit the back of my tv it would work sometimes. so, i improvised on some of the advice on this page and so far no problems. here is what i did (its very easy):

1. lay the tv on the floor and take off the back panel. (i think 12 screws)

2. on the right side of the tv (as you are looking at the back) you will notice a large metal covering that is held in place by 6 screws. unscrew these and remove the metal cover.

3. you will notice that the three screw holes on the left side of the board have some sort of metal or solder around them, in sort of a star pattern. when i looked closely i noticed that most of the metal (solder) was tarnished, or kind of blackened. (this must mean that the ground screws werent getting a good connection and this would explain why it would work sometimes when i hit it because it would vibrate the screws enough to get a good connection! )

so, take a pencil eraser and erase all the black or tarnish off the metal surrounding the screw holes. thats it! (to be safe i took some sandpaper and cleaned up the screw holes on the back of the metal covering, but i dont know if that was necessary)

at this point i followed another gentleman's advice to do a hard reset. this involved unplugging the 8 connections although i dont know if this was really necessary because i believe my problem was a ground issue. i did it just to be safe. his advice is on this site if you want to do this step.

4. i put everything back together and it worked! i performed a soft reset at this point which puts your tv back to factory settings. just go to menu>setup>reset>return to factory settings? yes
this will turn your tv off and back on. that's it. so far so good for me.

Samsung TV model un40eh53000fxza have sound but no picture


It all depends on the connections and cable.
If you are using a HDMI cable and have sound but no picture, then your TV probably needs to be fix.
if you are using a RCA cable or component cable, make sure that you have the correct TV input.
you don't specify what type of TV you have, but if I were you, I'll check the connections first.

No sound and no picture


The green indicator merely lets you know that power is getting to your TV. The absence of picture and sound could be due to power supply failure

Lg lcd tv 37lc2d no headphones socket - how do i connect headphones?


You can purchase a cable to connect to the Audio Out ports on the back of the TV. It will have 2 RCA connectors on one side that plugs into the TV and a 1/4" stereo jack on the other end that you will connect your headphones to. You could even pickup a pair of wireless headphones... they will have a volume control on them! I hope this helps.

TV won't "talk" with satellite cable


Try to see if you have 5volts for your EEPROM. If the voltage is normal try to replace your EEPROM or try to reprogram it. Your EEPROM is corrupted so that's why it will not store data.

Sound no picture


Hi, can you see the menus etc?

If not, then I had a similar problem that I posted. I recently got an engineer to look at my TV and they had to replace the main circuit board.

Once they replaced it, everything was fine again, but unfortunately the part alone cost me around £250 ($500) and then there were labour charges on top of this.

LG parts are very expensive apparently.

I'm no expert, but your problem sounds exactly the same as mine. Maybe try describing further - read my post here:

Audi but no picture when cable box conected through DAV-X1


It won't work as the DAv can only output to HDMI by bringing singal into the HDMI input.

why wouldn't you send it directly to the TV and Audio to the DAV? I sounds like you don't have an HD box anyway (otherwise why would you use an analogue S-video cable vs component or HDMI). Unless there is a distance issue then go to the TV.
