Nice video sir. What is difference between transformer and smps adapter? Please explain with video. 🙏
Very useful video. Thanks
good info! I am trying to trouble shoot 5800-p5l031-w000 board which has same issue ( low output voltage, and pulsating). But I can't figure out exact issue. Can you possibly help? Thanks
SIR mere ek 12V 1A ke adapter ke 4 diode 1N4007 or 450v 2.2uf capacitor short ho gaya he usko maine replace kar diya fir bhi adapter on nahi ho raha he usko mene check kiye ye component:
1. FSLl106HR ic open karke check kiya to koi bhi shorting nahi value de raha he
2.transformer ki winding primary secondry and aux. bhi ok reading
3. all smd resistor value ok
4. output diode ok not shorting ok value he
5.tl431 transistor and optocoupler bhi shorting nahi he mene open karke check kiyano shorting ok condition
6. output capacitor ok condition he
sir isme kya problem ho sakta he please reply dijiye
Ic hi change krke dekho

Sir 12 volt ka charger load ruk ruk kr le raha h to sir usme kya kre
Thanks
Cheque the adaptor in series lamp
I have a 12V 3amp adaptor now it shows 3.2 volts... IC change karne se problem solve ho jayega kya?
Sare component chek kr liye ho to bo jana chahiye
sir mere pass 12volt 1.2 amp ka ek wifi router ka adeptor he
sir usse mene invertor ki line se attached kiya but jb light jati he tab yo kam nahi karta jabki ghar pr baki appliance chalte he
or jab me ghar me 4 celling fan ek sath chalata hu invertor pr to yo 12volt 1.2amp ka apeptor bhi work karne lagta he
Adapter ka circuit (specially input side) ki pics send karu sir aapko
Pehle usko palat ke laga ke dekho matlab adapter ke dono sira phas nutral ko uske bad kam na kre to btaiye
Sir mughey 0365R based circuit chahiye.please answer me.

Bhai mere sath too ye ho raha hai ki mere pe ek 12 volt 1.5 ampere ka laptop charger adaptor hai vah theek kam karta hai main usse DC motor chalata hun 12 volt wala lekin jab use per motor per koi load nahin hota To vah to chal jata hai Lekin Jaise hi motor per load padta hai uski light band chalu hone lag jaati hai iska koi solution hai kya please batao 😔
Iska matlab uska overload protection kam krta hai mosfet shunt resister feedback sab badalna hoga
@@LUCKYELECTRONICSLAB please aap ispe ek lao 🙏🙏🙏
If the output is more than 12 volts, is it due to an Ic problem?
Ho sakta agar current sensing pin working nai kr rha ho to jada frequency janrat krne se jada mil sakta but akdam jada nai aata
Oswal blutooth speaker chala sakta hai wo v12 par chalta ha

Sir mere pas 24v ka ek smps power supply hai aur iska output volt blink kar raha hai... kabhi 20v kabhi 22v aur kabhi 21v mil raha hai ...iska karan kya hai please batai
Capacitor koi sa chek kro kharab ho gya hoga
Capacitor chenge kar diya hai fir bhi same problm ho raha hai
@@tapashaldar1506 to fir ic change krke hi dekhna padega proper frequency generat nai ho rha hoga
Bhai mere 12 volt adaptor me transform laga hai,, vo dc motor pe kam nahi kar raha....... Transfermar thik hai

Sir Usaki IC hai CC750 EL 817. Sir ye IC market me na mile to esaki jagah kaun si laga sakte hai.🙏
Sir mera adapter no voltage show kar raha hai, kuchh bataiye, kya problem ho sakta hai
Mosfet chek kro short ho gya hoga to ic bhi kharab ho sakta hai
