Power supply relay knocking, tv restartingOne 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 ic9201NARDINHO ALFENAS

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
