This is not the right method for repairing such sensitive equipments, the heat sink must be cleaned from dirty thermal paste before placing the new paste, transistor legs must be covered and isolated to avoid short circuit and electrical discharge caused by the dust, gates pulses must be tested with oscilloscope to ensure correct functioning of the gate driver to prevent transistor damage, after that a small layer of transparent warnish is needed to protect the soldered spots from humidity.
Thank you very much for the video but please i want to have th circuit diagramme of this MMA 200 . By trying to repaire my owne it will help me reconstitut the part that has been burned . thank you !
Amigo tengo una igual daño el diodo D3 y D4 y no se ve que numero es son los que estan al lado de los igtb son capsula to220 estan en un pequeño disipador si me puedes ayudar que numero es

Good tiçhing 👍👍👌👌👌👍👌👌👌👍
The oc light was still on after the repair
Ingco at total ay parihas lang ang board
Sir the j33 diode...what is the replacement?
Ponle audio
tengo la tarjeta me podrían apoyar armar es igual a la que están reparando
San po ang shop nyo?
