Amazing. Excellent presentation and nice demonstration.step by step explanation of the given backlight driver board.I think first time somebody has given schematic diagram of driver board so in case somebody wants to repair it it will be very easy for them.nice video for new n working technicians
Very use full sir ji nice Information (jo bhi Mujhse galtiya hoti thi Universal board lageneke time Ab is video se Sab mere Quarys solved ho jayenge) so very use full video banaya hai apne Thnx god bless you 👍
Sir aap ye schematic diagram kaise banate ho ? Multimeter se trace kar kar ke diagram nikalte ho ya fir already apke pass uss circuit ka technical data hai jiske help se aap diagram banate ho ? Kindly revert

Sir isme vvc 19.5 volt pe dene pe beck light biling ho raha he or vvc 12v dene pe tik chal raha he or aap ne bataya ki 19v se 40v in de sakte he rong sir
Maine ye circuit combo board 40 inch ke sath lagaya lekin jaise hi stand by release karte hain 47 mf wala capacitor blast ho jata hai. Stand by mode mein blast nhi hota hai aur led connector ki pin par 63 volt show hota hai. Maine LED strips ko connect nahi kiya hai, kya ye load na hone ki vajah se hi blast ho raha hai ? Please help.
LED strips connect karne ke baad AC supply on karne par blast nahi ho raha aur backlight bhi jal gayi. Lekin light constant nahi hai flicker kar rahi hai. Backlight jalne ke baad circuit mein 131 volts aur 110 ma current show ho raha. Jo niche ki side mein 6 smd resistance lage hain unhe jumper se connect karne par bhi light intensity ya current mein koi change nahi ho raha, current 110 ma ke aas paas hi rehta hai. 10 led ki 4 strips means total 40 led series mein lagi hui hain.
