Totally inoperative | R 410 (6,8 k) | I started checking the power supply, but it was normal, I tested the horizontal oscillator which wasn't working. I then started measuring voltages on the ci 401 pins and came to the conclusion that the defect was at this point, as I found only 4 v instead of 12.7 v on pin 15. I removed the resistor r 410 which was altered. Replaced the resistor and the TV started working normally again. | M&E ELETRONICA |

Tsh burns without apparent cause. | When you turn on the TV, sometimes the TSH burns out quickly and sometimes it works for a few hours or even days and burns out again, so when you see the board you can notice that in the part of the horizontal drive and in the CI 101 that generates the horizontal signal there was a broken solder. , so I redid the solders on both the drive and the ci so the tsh stopped burning immediately but it was still burning due to overheating, I couldn't find the original which was the 2sd1649 so I put the 2sd1650 which didn't hold up, maybe because it wasn't original, then I placed the 2sd1554 which had a very important characteristic that was different from the original, the tf fall time which in the original was 0.4us and in the 2sd1554 was 1us, I then placed the 2sd 1877 which had, in addition to the voltage and current, the same as the The original also had a shorter fall time than the original, and the TV started working normally again. | ||
