| MONITOR LG FLATRON |
EZ-730
|
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 | |

This TV has +b high, 139v and it was supposed to have +- 126v, pins 4 and 6 of the vert output have +18, -18 confirming high fan; already check the primary power supply is normal 295v, and tsound is also a small stretch of the image hiding the broadcaster symbol | It was q830=431 that switches the power supply and it was bad. | BF.COLATINO | |
