Not power Hp laserjet 1020,1022 ,Canon lbp 2900b power testing basic troubleshooting good testing

Fuser heater on ni ho rha start me, 50.0 error ata hai , solution bta dain

[@SuryaComputers_Elec]

Hp 1020 plus, switch off hone par switch ke pins par 206 ac volts (actual volt 252) hai but, switch on karne par zero volt hai.

[@trcteck]

Fause check kro fir supply

[@santanusingha6622]

Mosfet ke pas Resistance jo apne kaha open hai,konsa value lagaye?

[@trcteck]

0 value

[@zoheb4you2002]

On hone ke baad off ho jata hai...400volt capacitor mein voltage 300 constant hai....

[@REED_GAMER7]

10ohm fuse burn ho ja rha hai ...kya kare...optocoupler ka kya role hai

[@trcteck]

Change MOSFET

[@REED_GAMER7]

Thanks

[@pankajagrawal6145]

24v ki jagah ydi 4v mile to kya Krna chahiye

[@trcteck]

Check primary section

[@sharkjeev]

If I have Zero voltage at capacitor, and the fuse is good, so would the capacitor be bad. There is no visible leaks on the capacitor.

[@trcteck]

No check primary section MOSFET & resistance

[@KusumJain-qp9sk]

Output me 5volt ban raha ha 24ki jagah kya check karo sir

[@trcteck]

Secondary aur primary

[@LalitKumar-rc4tl]

Sir mere printer ki power supply ka fuse bar bar udd ja raha hai kya probme ho sakti hai

[@trcteck]

Check out put section

[@VSGarments-q8h]

nice video sir

[@semjln461]

Sir ji 24 volt bhi bam rha hai lekin printer on nhi ho rha hi kya problem ho sakti h

[@trcteck]

ECU logic card short ho sakta hai

[@prabhatraj786]

250 volt fuse pe beep nhi aa rha....kya mjhe ise change krna hoga?

[@trcteck]

Ha par MOSFET aur diode check kar lena aage shorting na ho

[@arupmandal8678]

DIOD VALUE KEA HEA?

[@trcteck]

4 to 8hundred

[@banksoftwareandhardwareset93]

[@trcteck]

Mil jayega

[@ASN107TV]

Thankyou sir

[@prabirmukherjee4165]

1020 out put voltage 2.5 volt where is fault. Main capacitor voltage 300 volt ok

[@singhraghvendra0006]

क्या करें

[@trcteck]

Opto coupler

[@singhraghvendra0006]

Ok करता हु सर जी 🙏🙏

[@trcteck]

🙏🙏🙏

[@singhraghvendra0006]

24v की जगह 53v आ रहे है

[@trcteck]

Not possible
