TV turning off by itself and sometimes with a black background blurred with red | I resoldered the power supply, checked the electrolytics, washed the board with teener, but it didn't solve the problem. | I saw sticky oil on the signal plate above and below the plate, I removed the square wafer of thermally conductive silicone rubber, I washed the entire plate, I cleaned it well, I dried it with a hairdryer, I adapted it with insulation in its place, the aluminum heatsink with thermal paste, I glued it only to the corners of the insulation and the heatsink, the problem is gone | Tulio Moreira |

Defective automatic start and return, speed varying | Pci power supply: q101 q102 q103 q104 (bc 548a) r 114 - 4k7, r 116 - 8k2, r 117 - 4k7 pci controle: ic2 e ic3 sn7400n ic4 sn7410n | It arrived with the speed varying by 33 rpm, almost imperceptible, but it was varying downwards, and the arm did not move automatically, someone had turned off the arm's motor because they could not solve the defect, it went to the beginning of the record, went down and came back. for rest. Analyzing the diagram I saw that the arm control is done by ic 2,3 and 4, when changing, it worked normally, in terms of speed, I replaced all the electrolytics which were in bad appearance, yet it continued to vary, changing the resistors for new ones. speed became more stable, but still varied, the solution was to replace q101,102,103 and 104 without testing. | Trendset |

With am, without fm | Q1,q2 (bf324) e ic1 (an 7220) | It arrived dead, after changing the transformer, it only tuned to am, after a lot of brainstorming, I replaced the an7220 (the 7222 is not suitable) the fm appeared but very low and with a lot of hiss, I decided to invert q1 and q2 (bf324) the fm appeared clear and loud. think of a good tuned radio! | Trendset |
