Doesn't start. Defective standby power supply. defect caused by the plastic underneath the PCI which rots and releases conductive oil and which also corrodes the board | Replacement of the IC pwm of the standby power supply s3330 position ics801 and the 1Ω resistor position rs801. Clean the board thoroughly and check for possible corrosion spots that could cause other defects on the board. | rafaelmoraes99 | |

Sometimes it doesn't turn on, it doesn't even light up on stand by, sometimes it turns on | Do a test with a thermal blower or a head heater on the main board, if it gets hot and turns off, replace the capacitors c1024 and c1025 with 10uf/25volt electrolytic capacitors, note: observe the polarity, just find the negative side with a multimeter on the device's chassis | reginaldo moronte,eletronica junior caldas novas | |
