Hi There!
I am currently serviciing a plotter versacamm sp-540v
I found a shorted mosfet labeled J553 which corresponds with SJ-553s (surface mount)
Neither local stores nor other webpages that are able to provide it before 1 month (only aliexpress, with 1 month delivery) can provide this part
I need to find a substitute for it. Can anyone give me a hint on a part that I can use to replace it?
Also, given the schematic Im attaching (pg 36, transsitor Q1) , does it make sense that the whole machine won't turn on when I press the POWER button on the panel? This part serves as a switch to start the heater so this kind of explains the spark I get as soon as I plug the PS DC wire to the board (indicating high current flowing even when powered off) but not sure if this makes sense with not being able to start the whole machine.
Thanks everyone in advance!
