| TVC-SHARP |
C-2013
|
TV sometimes the image disappears and there is no image for a long time, but it has sound, channels and high voltage. | This defect is caused by cold soldering of the h cable that leaves the main board and sends voltage to the trc filament. Resolder the cable h that creates filament tension. This defect is also characteristic of sharp and cold welds due to time of use. | BENICIO S. MADUREIRA | |

No audio, or sound sometimes fails | Cold solder on the cable that leaves the main board and goes to the speaker, close to IC 301, TDA 7056. Resolder it and everything works normally again. This simple defect is characteristic of Sharp as the solder breaks a lot due to time of use of the device. | BENICIO S. MADUREIRA | |

The TV turns on for 2 seconds to 4 seconds and turns off. | When you plug the AC cable into the socket, the TV turns on and off, and does not turn on again. But if you invert the AC cable position, the TV turns on and off as before. Don't have any doubts, disconnect the IC 501 vertical output pins and the problem will be solved. a small internal short in the ci tda3653b makes the horizontal oscillation disappear. also check c 504, but it is rare for it to fail. there is a check for the trc board socket, as this socket breaks the pin that connects to the screen due to time of use, it is cheap to change -o. another tip this defect looks like a horizontal output transistor with leakage or open flyback or IC 8380a internal defect, do not replace them, as the defect is ONLY in IC 501. | BENICIO S.

Turns on, after some time of operation it turns off and turns on again and so the time decreases until it no longer turns on | STK 73907 power supply regulator with problem. Note: all power supply secondary voltages work normally | Replaced the regulator and the TV was ok. | George Pontes |

It takes a long time for the image to appear | AC voltage supplying the kinescope filament very low. | Take about 35 cm of number 8 wire, turn the fly-back ferrite 4 times, remove the original filament connection; and connect and connect the wire that was wound on the ferrite on the kinescope filament...pin 4 and 5...ok. | Armando |
