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 |
