This TV arrived with bu2508dx horizontal output, | After checking the power supply and peripherals and not finding anything abnormal, I put another bu2508dx on. The TV works normally without any heating, but if I turn off the TV using the remote, a very thin whistle starts and in a few seconds the horizontal output catches fire to the point of burning. | Solved after placing transistor d2624 horizontally.thanks | BF.COLATINO |

Once again; tv toshiba2066mu. this time with weak video signal. well; I started by checking that the control processor was normal because the characters in the contrast function worked normally, increasing and decreasing the dashes content. | But the video signal remained the same, very weak | When measuring the voltage on pin 30 of IC 601 TA8718N I saw that it was wrong. Following the alignment of this pin (the trail), I found R210 open at 20K. I just replaced it and the video returned to normal and the contrast returned. | BF.COLATINO |
