hello everyone!
i am new to this forum and i was hoping to get some help on a little problem i encountered!
i managed to fry a component on the pcb inside my spektrum sm1001 ko-propo module mounted on my ex-10 helios..... and it's so burnt that i cannot identify it
these modules cost a lot and i cannot buy another one or find one on ebay.... so i am looking to replace the burnt component on the pcb with my limited soldering skills

!
anyway, if someone out there is still using this obsolete module, i would really appreciate some help, like a photo of the back of the pcb showing clearly the components, unfortunately it's my first post and i cannot attach a picture... this component is a small squared black chip/resistor/fet.... that has 4 legs and is located just under the the hm5 94v-0 writing on the backside of the pcb
thank you in advance guys!
p.s: a photo of the pcb is in my photo album! (thx roelof!)
