![]() ![]() ![]() Off to my friend home and I re-installed back the power board and after applying the power the television came up beautifully. I checked the output voltage and got the 3.3 volts standby, I used a 10K resistor to link between the standby and power ON pin and other voltages were generated and with this I concluded the power supply is okay. I applied the power and the bulb was bright then dim, with this I concluded the power supply had no other shorted component. I changed it directly since there is no point of testing a swollen capacitor, whenever you get a swollen capacitor kindly send it directly to the dustbin and that is exactly what I did.Īfter replacing this one capacitor I decide to use my series bulb current limiter ( you can make one easily by visiting this link) I pulled my meter and tested the fuse and was found okay, the bridge rectifier was also found okay, on close observation I noted the top of the main capacitor was slightly swollen and this is an indication all is not well with this capacitor. One my workshop bench, I began by scanning the board with naked eyes and seems like no catastrophic damage on any component. Orders started trickling in and my first order was from my good friend and neighbor who lost is Sony SONY LED TV MODEL KDL-32BX310.įrom my experience when equipment’s are hit by power surge, the culprit is usually the power board, I visited the home, opened the television and picked the power board and off I went to my workshop. Since I had warned them about the abnormal high voltage, I send them my condolences for the loss (dead) of their equipment and assured them that hum-tech electronic is open 24/7 to see them back on air seamlessly. I logged on to our estate what’s-up group and broadcasted that power is abnormally high and therefore those with electrical equipment should disconnect them from the power outlet.īefore finishing writing the text I noted unusual influx of comments coming from every corner of the estate with complains of equipment’s smoking and instant dead. ![]() My meter is three phase and after checking other two lines, I noted they have more than normal voltage, actually 421 VAC instead of 240 VAC here in Kenya. ![]() SONY LED TV Model KDL-32BX310 Hit By Power SurgeĪ few days ago I noted power in my estate was dim and being an electronics technician with basic knowledge in electricity I decided to visit my electricity meter to find out what is happening. ![]()
