Same pcb hay problem hay all relay no working but NPN transistor jab collector Or emiter short karra hu tab relay click karra hay ka control er ka problem ho sakta hay ka please reply sir ji
Panasonic CT641M Grill, Convection microwave ke PCB ka power supply aur sab relays OK hai, display bhi hai par relays energise nahi hote, output nahi hai. Iska touch pad micro switches se replace kiya hai display barabar hai lekin start button press karne par PCB nahi chalta. kya problem ho sakta hai ? please help.
What is the cost of this PCB and from where it is available. My Microwave oven only one key pad microwave is working and start stop convection timer keys etc not working. what could be the problem PCB or keypad.
sir filter capacitor ke baad resistor kyu lagaya.. jab filter capacitor hi voltage aage flow kar raha hai to fir capacitor ke baad resistor aur fir wapas capacitor kyu ?
Register between two filter capacitor acts like a fuse... and when any DC voltage passes through resistor it becomes impure.. so to make it pure DC, second stage filter capacitor is required..
excellent knowledge sharing of circuit board espcially for layman like me who dont know ac n dc also trying to repair my microwave of lg
Good Vidio
Nice no.1
Veri nice👌👌👌👌
Very well done videos. Appreciate your efforts and your knowledge
need help in knowing where to buy the door lock for lg microwave im mumbai
Sir NTC pe ek video banao please.. yaha pe i button laga dena for reference

aap ney lg kabhi same video banaya hey toh pls send kijiye
Sir mujha cercuit repair sikhna hain practically. Please help?

Exelent brief somemore.thanks
Very helpful video sir
Transformer to DC voltage pe work nai karta hai brother
Agr ntc khrab h to kase chek kare
Excellent
Very very useful.
Kindly upload a video on NTC please
nice information sir thank you
sir capacitor value 4.7mf/500v
Chopper ke pass jo diode hai vaha 12v na aa kar sirf 6.5 volts aa rahe hai
Nice video
Thank you sir
Cap value 4.7uf/500v hai sir pls update
Mera pcb repair karke dijiye

@@technicalsuvidha2017 why can't we keep single filter capacitor directly connect to chopper transformer?
Make vidio no supply to all really
