Tv lg 29fu6tl no image appears sound is normal lights up the filament has high voltage but no image appears | Loosen the screen wire and measure the screen voltage by adjusting the screen potentiometer minutely, it should vary around 450v +or-. If the voltage varies, the flay will be fine, if it doesn't vary, the flay will have to be replaced. check the screen's polyester capacitor that goes on the tube plate. Another test to be done to see if the tube has a shorted filament: loosen the tube socket pin (the socket pin where the screen wire goes). | Turn on the TV and use a screwdriver to tap the socket pin against the track where the screen wire goes, do this several times suddenly until the image comes out. It's already happened to me here where I just loosen the pin from the socket where the screen wire goes and turn on the TV and the image opens and then I just solder the pin again and go for the hug. | MAURÍCIO |

Flatron ez-730 - image with intermittent aliasing | Occasionally the image was distorted only in the contours and persistence or shadow in the image, like a ghost and all of this manifesting itself once a day, when it did. | I came up with the idea of replacing 3 ceramic capacitors close to the fly-back, without success initially, but when replacing the c406 the defect never returned. | bf.colatino |

This TV has the standby LED on, when I turn the key on the LED goes off and comes on again, but you can see that it generates mat for a short moment the tube brightens and goes off again | This TV gave me a hard time, but I managed to solve the problem, after I had nothing left to watch I noticed that the tube's cannon was lit, but I hadn't noticed it before. | So I decided to increase the scrin adjustment and the bright line appeared indicating closed vertical, as my colleagues said, this TV likes to have a defect in the vertical, but it was not necessary to replace the vertical ci, as the defect was the open r313-82k. | bf.colatino |

This TV arrived with this defect of working with a normal image but without audio, it only had audio if you put it in a/v and turned on a DVD | Well, it turns on the a/v and audio comes out, it was obvious that the sound output wouldn't be burnt out, I checked and got to the q501 which was a c3198 and it was burnt out when the TV was replaced and it worked normally. | BF.COLATNO |
