Green LED flashes and off
- Joined: May 4th, 2012, 6:18 am
I have got a 15 inches LG crt monitor. when it is turned On green LED flashes and after a second it off. The monitor model is TG5700G. I replaced flyback transformer, STR, Main filter capacitor and all electrolytic capasitors in the primary side of the power supply section and some of them in the secondary side I checked all the diodes, resisters and transisters in the circuit but they all are Ok. One burnt (open circuit) resister was found in the primary side of the power supply. It was 560K 1/2W resister connecting the two pins of main filter capacitor. I replaced it also but no any difference. Please help me to solve this.
