Turning off after 30 minutes on | This defect is on the power on line. remove the transistor that powers on the main PCI, the trnasistor is conducting from collector to emitter, the collector is connected to pin 14 of the ps on line power supply connector, the emitter goes to gnd, replace it even if the measurement shows OK | Chico Alagoinhas | |

Sound turns on and off, vertical good correct voltages but turns off immediately, without h-sync voltage | 4k7 resistor r305 open... the person changes the deflector capacitor, changes the micro memory and nothing solves it... etc.. | Changing the open resistor r305 4k7 or diode 1n4148 that goes with it is to see that tsound is this diode together with the resistor. | tvcell |

Screen off | At first the defect was on the main board and after I changed the memory the screen came on and the image returned, but when I turned it back on again the defect had returned, I changed the y and the power supply and nothing, I changed the main one and nothing. | Replace or rewrite the eprom of the s24c32 memory screen drive board and I couldn't find anyone who sells this memory and I had to remove it from a board of the same model that had a broken display. | marco.32 |

Arrived at assistance completely dead. After visual inspection and with no apparent defect in the power supply, I verified that the fuse was open. In basic measurement of the diodes, I found the n-channel MOSFET, reference 13nm60n, 11a/600v, in the qp801cs position, shorted. | After changing the MOSFET and fuse, it worked normally again. | AnisioH | |

The TV started turning off and on, then with use it stopped turning on, it kept showing the "logo" and turning off, then it didn't turn on again! | When turning off the main board, the backlight lights up normally, giving the false idea that it was a defect on the main board, but when measuring voltages I noticed that they varied a lot, I tested the main board with an external power supply and tsound was no high consumption. | So I replaced the icm-8015 on the power supply board, which is a strw6035s, and it worked perfect! | SCINFO |
