Sir Whenever I'm switching in DC Supply voltage(200vac) my system is working better but whenever I provide the 230vac then my MOSFET is going away ...and also One more doubt i observed the voltage at the EN/UV pin is 0.486V but as per datasheet mentioned below 1V the switching will be terminated how I'm getting the output voltage and is it related to failure caused???? Kindly explain sir..I'm unable to get it🙏🙏 And also if I think transformer primary is getting shorted that's why the IC has failed even it is shorted as it has the current limit comparator how the IC is damaging????
hi .i use 278 and use datasheet diagram.but ic was expluded.what is wrong?but i not use feedback .just want yo test and then use feedback.i think the feedback i not reason that explosion.help pleas.
En/uv and Bp volt ok but secondary volt not come to kya kare And primery and secondary me jo pf laga hota hai vo mene axy and secondaey me lagaya hai to isase koi problem ho sakti hai
Meray smps k circuit mein tny 279pg uc laga hova hay. 12 volt ko 14.5 mein convert krnay k liay 12k resistance lagai. Ab smps on nhi ho raha. Fan chal k ruk jata hay. Over voltage protection ko kaisay disable kia jay...? What will be the solution to turn on the smps .....? Model no. Hp DPS 240TBA.

Salam...sir mere pas panasonic ka home theater hai Us mai mip2f2 kharab hogyi thi wo mene change krdi wahan 5 volt to agye but us K main transformer ki switching ic strx6768 switching kar rahi hai series bulb mai lagane K baad starting mai bulb flactuate karta hai phr full short ho jata hai mene optocoupler pe voltages check kiye to us Ki photo led pe voltage nahi arahe but jab multimeter Tl431 ic ki reference pin pe positive probe or negative probe ground pe laga raha ho to IC perfect switching kar rahi hai ... mene optocoupler bhi change kr liye or tl431 bhi change kar li phr bhi same issue bana hoa hai .... sir kuch solution batye is ka ..... jazakallah
Assalamualy kum bhai Samsung ac pcb smd transformer 7 leg hay Primary winding 3 leg hay left and right pin ohm 0.6 but center pin 0 om's aur koye transformer Laga sak Tay hay
Sir important and informative video. I have a question, most of the time I find sm transformer in LG split AC pcb is faulty that's rusted, it's primary winding resistance is 3.0 ohms and secondary is 0.4 ohms , so I am not getting transformer in the market. What is the another option to fix? Can I use 12 volt adaptor sm transformer? Please make a video and advice. Thank you.
Sir inverter ac out door unit me smps power supply ic no. 3A462H. E hame mil NAHI Raha he. Please sir hame eska equelant batae . Hamara bahot Kam aega. Please sir. Assalamualaikum please please please. Meherbani kare. Me Bangladesh ka ho . AP ka subscriber
Hello Sir, I have problem in air conditioner pcb smps with switching ic TNY276PN. It gives supply for 1 to 3 min. after that stop the supply. No voltage obtain on drain pin after it stop working. I also replace the switching ic but same problem exist. Pls reply what to do.
Aslam o alaikum bai yaar mery pass lg home theatre hai us ka ic burnt-out ho gaya hai us ka no nai mill raha us k no kaisy pata kar sakty hain apna what's app no dain plz

Hello Sir, I have problem in air conditioner pcb smps with switching ic TNY276PN. It gives supply for 1 to 3 min. after that stop the supply. No voltage obtain on drain pin after it stop working. I also replace the switching ic but same problem exist.
Pls reply what to do.
please re-solder smps transformer
check output side capacitors. some capacitor may be short circuit internally
Thank you very much sir
My smps problem solved after resolder smps transformer.
Hats off to you.
