sabse pahele adopter ke 19v. ko check karenge. phir 19v. socket ke output par check karenge.19v.input hokar 19v. output kar raha hai ki nahi wo mosfet ko check karenge. stand by mode me hum 3.3v., 5v., aur audio ic par 19v. ko check karenge
stanf by mode se relise hone wala voltage ko check karenge jo ki 1.3v. , 1.5v. ko check karenge yadi ish me se koi voltage nahi mil raha hai to hum ush voltage ke ic ke input voltage ko check karenge aur out put par shorting ko check karenge.
ye total voltage mil rahai hai phir bhi tv on nahi ho raha hai to softwere kar ke dekhenge .ye bhi kar ke dhekhne par bhi same problem hai to main ic falti ho sakta hai to main ic ko change kar ke ok karenge.......etc
ya
Adopter se 19v. input denge dc socket par ye 19v. audio section aur backlight section par direct input ho jata hai.
panel voltage ke liye reguletor ic laga huwa raheta hai . ye reguletor ic 19v. input lekar 12v. panel ke liye out kar ke panel par chala jata hai.
Usb voltage ke liye bhi reguletor ic laga huwa raheta hai ye reguletor ic 19v. input lekar 5v.output karke phir se reguletor ic par in put hokar reguletor ic ke output hokar usb ke liye out kar ke usb par chala jata hai
3.3v. ke liye bhi reguletor ic laga rahete hai ye reguletor ic stand by mode par hi 3.3v. out karnelagata hai ish me 19v. input hota hai aur ye voltage bios ic par, main ic par input hojata hai aur ye 3.3v. ek aur reguletor ic par input hota hai aur ye reguletor ic se 1.5v. out hokar main ic par stand by mode par hi input hojata hai. ye 3.3v. se 6 leg wala mosfet par in put hokar ye mosfet stand by mode ke relise karne ke bad ye 1.5v. out hokar main ic ko chala jata hai .
Aur 1.2v. ke liye bhi reguletor ic laga raheta hai ish ic par 19v. input hota hai aur stand by relise karne ke ba ye 1.2v output par dekhne ko milega aur ye voltage main ic par chala jata hai.
ye tino voltage {3.3v, 1.8v. 1.2v } me se koi voltage miss hojane par tv dead rahega .......
