TV doesn't turn on and keeps beeping | Horizontal output (q602) shorted. The horizontal output was replaced, the TV turned on, but the horizontal output burned out again within a few seconds. wide capacitor (c616) of 8.2nf had its value changed to around 1nf and burning the horizontal output. The problem was solved by changing the horizontal output and the wide capacitor. | Replace of c616 and q602 | sergiofne(at)gmail.com |

Complementing "flashing" screen defect. | Cold welds in the power supply region. | Analyzing the defect further, c716 was also found to have a defect in the solder and thus correcting the others in the power supply area. Before these corrections, it was possible to observe that the voltage on the collector of the horizontal output transistor was very reduced and after re-welding it returned to the correct values. | py3ig |

Without characters closing the vertical and sometimes turns off when tuning | R671, r642, r665 open and d609 shorted, probably caused by oxidation at their terminals | Replace r671 from (27k), r 642 from (100k) r 665 from (150k) and d 609 from (1n4151). After the replace, the TV was ok. | GEORGE PONTES |
