Thanks for the video. I uses this LG micro oven. Just few days ago this inverter became out of service. As a result no heat is being generated. But all others okay. Please let me know how can I fix the problem. Two Resistor 50 ohm got opened (these resistors existed under the transformer on PCB) replaced through 47ohm (in Bangladesh 50 ohm type not available) but fault remain same.
Hi Rahman - I am also having same problem and the resistor is not 50 ohms it is 50 mega ohms (colour is Green - Black - Blue - Gold) on my digital multimeter not reading the value but I did pass 9 volts at one end of the resistor and another side i get voltage out - not sure about this weird problem both power Diode are good both IGBT is good and bridge rectifier is also good (manetron is also good :)) - ordered online replacement PCB board 90$ .
my inverter shots the high voltage diodes why its the same for LG Neo chef
hello sir the schematics of this power supply is required plz.
Sir how to buy original magnetron for LG
I need 4 inverter boards ..where can I buy them in India..?pls help
Nice info sir
Sir inverter mw ki non inverter mw Bana sakte hai kya
Start button press Micro oven 10 second run next time stop and display to F-11 every time no select what is solution
Sir is PCB ma diode bar bar khrab ho rha hai kya kara
Wish it was in English. I have no idea what was going on. Microwave not heating. Magnetron tests OK. Next the inverter, but how?
