{890} SMPS have no output voltage 

capacitor is good, no need to change capacitor. the power transistor is short circuit so it is not blocking voltage. in normal condition each capacitor's voltage must available at each transistor's collector to emitter. if any transistor is short circuited, then it will not hold VCEO, in result all voltage will appear at the opposite transistor. so the power supply cannot take startup

@@HaseebElectronics What is the cause of the transistor burning.. Is it an overload or distortion in the pwm signal or the discharge elements and the transformer coil have a faulty diode, capacitor and 47k fast resistor

if one is working good, then i think no need to replace. as it is in bipolar drive, so it will work normally

Trace the circuit with what ever other components are still unremoved including switching ic. Match for ckts. You can find it out.

Look for data sheets or replacement tables..

i was checking that, is there some burning sign or smoke sign

@@HaseebElectronics it didn't appear that you made any mention of the caps possibly being shot, You didn't check the E.S.R Burning smells are fine, if it just blew up now, but if it's been a week or 2 the smell wouldn't be there You touched it with your fingers then.. thought nothing of it Great you swapped the Transistor, You didn't check other possible faulty components as a result of the short

the capacitor ESR test is needed when the supply don't drive the load or it fluctuates or the power MOSFET or fuse burns out if the circuit works fine, then mostly I skip the ESR test

@@HaseebElectronics Sure... Respectfully mate (My Fellow Electronics brother) I've been doing this since i was 6, I'm 49 we all have our things, don't we. there are foundational rules such as (always test voltages first) but then we all put our own stamp ME... I have seen too many situations where i should have tested E.S.R. on Caps and... time and experience has taught me that i should Besides it only takes you say a few seconds more to test 2 or 3 caps or maybe 1min to test them all when i repair, i basically do what you did, i follow the voltage i find the fault , i replace one thing at a time BUT I ALWAYS DO HOUSEKEEPING AFTERWARDS if all seems ok, i'll check basics like ESR on caps Resistance on Fuses Just in case and i have had scenarios where i have seen High resistance on fuses even though the circuit works and high ESR on caps when it was all working and changing them out as well since it's open saves time fucking around later on but hey, again, we all have our own way we do things that's how i would have done it but yeah, mainly because you had all that blackened stuff, I NEVER LOOK PAST THAT

salutes and special thanks for your valuable comment you are exactly perfect

As an energy "tank" or receptacle during the AC zero-crossings.

Look for data sheets or replacement tables..

NO! Used to charge lithium cells will result in uncontrollable fire!
