Power supply relay knocking, tv restarting | One of the likely causes could be the c.i. LED driver. To find out if the defect is in one of the two, simply measure the voltage in diodes d9001 and d9002, if tsound is a high level in either of them, the defect is in the c.i. corresponding to the diode in question. if tsound is a high level in the d9001, the defect is the ic9101 and if tsound is a high level in the d9002, the defect is the ic9201. | Replace ic9101 or ic9201 | NARDINHO ALFENAS |

The power button doesn't work and it's not the membrane | Leaky display | Leaky display. all segments light up, but when you try to press the on button, it doesn't come on. The solution I found, since I didn't find the display available and changing the board was unfeasible, was to place a diode (1n4007) in series with the shorted pin, with the cathode connected to the display and the anode on the track. To identify which pin, just release one by one until the microwave turns on, in my case it was the first pin on the left next to the CN6 connector. | Miratec Eletrônica |

When disconnecting the cable from the main board it returns 5v, when connecting the cable the 5v drops to 2.7v. If you force the power supply board to turn on on the bench, it will release all voltages and turn on the backlight, but the defect is still on the power supply board. | Change without testing the capacitor c9353 (330/16) (silver) and it will solve the problem. | ||

The network relay clicked every 3 seconds and it didn't activate. works only in battery mode | Transistors that activate the relays changed, replaces all (q20, q19, q17, q16, q11). they are smd. I removed it from another board. it started working normally again. | Jhonatan Morais | |

The TV couldn't start, the screen was completely dark even when the screen was raised, and it was constantly restarting all power supply voltages, ok, pulse signals, ok. You already see them missing. I found the voltage of 5v that powers the computer with 3.6v. | After changing the micro ci and the symptom didn't change, I released the 733 jumper and the 5v came back on the q606, I decided to loosen each piece connected to the 5v line so I got the ci 801 (btsc stereo decoder) shorted. | Replace ic801.
