No picture i turn on x box and is running with sound but not with pictures. I have checked cables and all seem good.

The TV electronics for the picture may have failed. Do you get any picture ever, like when you turn it on, or when you connect a DVD to it?
If you do then replace the scart cable with a good known brand. Cheap scart cables often do not have all the pins connected up.

Does say a dvd player give sound when connected to the same input? If you have determined that the source is good and the speakers are turned on in the menu then I would replace the main board.

Hi, troubleshoot first before going to the board of the TV to be sure where the problem is from.

How to Troubleshoot an LCD With Sound But No Picture


It can be overwhelmingly frustrating when an electronic device as expensive as an LCD television set starts having problems. Luckily many of these problems are easily troubleshot. While being able to hear sound coming from your LCD television but seeing no picture may seem serious on the surface, fixing the problem involves checking a few different settings to make sure everything is set properly

Instructions

Check the video connection of any devices plugged into the LCD television. If you can hear sound but are seeing no picture while trying to use something like a DVD player or cable box, the problem is probably that a wire is loose somewhere. Check the yellow video cables running from the DVD player to the TV and make sure everything is plugged in firmly and where it should be. Also check the coaxial cable running from the cable box (or cable outlet) to the television and make sure that wire is also screwed in securely.

Check the image settings on your television and make sure everything is set properly. Certain settings like "Picture" or "Brightness," if set to one extreme, can make the picture appear completely black. This could cause you to simply hear television shows but not be able to see them. Reset all picture settings on the TV to their original factory default settings to see if that fixes the problem.

Try another channel. If you're watching TV and not getting a picture, the first thing you should do is check a variety of random channels to make sure it is a problem with your TV and not with your television signal. If it is a problem with the television signal it is the fault of the TV station or cable service provider and there isn't anything you can do yourself to fix it.

Try the DVD on another DVD player. If you're trying to play a DVD and can't see any images, make sure the disc isn't defective. Try it on another DVD player or a computer DVD drive and make sure the disc works in the first place.

After troubleshooting the above and no solution yet, problem comes too from the power or the Y sustain at the left or right side of the display when one of the large capacitor or heat sync on the capacitor even the flat power cable connection it to a main power board needs to be checked too, if the fuses on the board are blown it will need to be replaced

But after replacing the fuses and the capacitors and still no solution,you will need to replace the all board ..

Hope it helped ..

This sound more like a cable issue. Also check the leads going from your cable box to the set/ If you are using component cables one of them may be loose.

Unplug the cable box for an hour,replug it back in.Should get the cable box to reboot to updated the softwares.Might work than,tv seem to have picture,somethings on the screen,words mean ur tv still works.

Sounds to me like you may not have service on your cable box. I worked for a large cable provider for years and that was generally either a faulty box or the box just needed a "signal" sent to it. Try to bypass the box complety and just hook your service directly into your TV. You may need to go into you TV's menu, switch it to the cable setting and then auto search, but most likely the TV is new enought ath you should be able to get a picture. We do know that it is not a problem with the TV since you are able to view other devices on the TV. If you get a picture then we have narrowed it down to the bow. Although this may not mean that the box is bad. First let's ensure that if is installed correctly and that the input jack is the cable from the wall and that the output runs to the TV. Again you have sound so i know this seems dumb but so can be cable installers. :) Since we know all of that is correct and you still have sound but no picture, I'm going to say that you most likely have a motorola box and on the front of it there is a small button that has a/b next to it. (most commonly found on motorola box but not limited to). If that button does exist on this box i'm almost certain that will correct your problem. If not you have a faulty box and should ask you cable provider to replace it.

clean the heads. check out my tip

sweetkiss, if it works through the dvd player and not on cable/satellite box then the tuner is bad, if you have any type of cable/satellite box try running A/V cables out of the box to video input on the back of the tv and switch the tv to that video input, ie; vid 1, vid 2 etc. (your using one of those inputs for the dvd) this will give you your picture back, you can of course also replace the tuner in the set, good luck, BMW Rider

IF you are saying that every thing is connected properly check your video cable it could be bad use a new one if that does not rectify your problem it is time to call in the tech you could be having problem in your video circuit but you did not mention if the screen light up with no picture but with sound or it does not light up blank with sound.however there could be two things 1 if the screen lightup with normal sound it could be a leaky ,open, or shorted, transistor or ic in the IF circuit.2 If the screen does not light up and has normal sound it could be a defective horizontal stage.so it is time you take the set to a tech for repairs.good luck.

I am not familar with that particular set, but this is what I would check (assuming you don't have a surround sound system hooked up to it as it would sound like a tuner problem otherwise). If you have external Audio/Video jacks with cables hooked up to the Direct TV box, move the video cable and see if you lose video when it is jiggled. If so, you either have a bad cable or connection/connector. When you say you have to turn the TV off for about 30 minutes, do you leave the directTV box on? If so, then the problem seems to be with the TV. Otherwise, maybe the direct TV box is at fault -- leave the TV on and turn off the cable box for a half hour and try it again. You have a few possibilities here, good luck.
