After a while, I found out that similar MB issues are common with the Samsung A53 model. Local repair shop gifted to me three bad A53 motherboards to play with.

I will measure voltages and RTG values on each, then compare. What method/software for writing results down you recommend?

[B]Samsung A53 [/B] [B]5G SM-A536F dropped, screen cracked. replaced. Phone works now, but switching off intermittently. It doesn't turn on at all if phone is assembled and all screws are in. When motherboard is loose, it works. I suspect, there is a crack in the MB or pin on some component. The question is:
is repair attempt feasible and what is the best way to do it? [/B]

Hello everyone,

I've been on this forum for quite some time and just now read WELCOME message! Better late than never, so here I am. Since my first visit, I managed to assemble quite good micro soldering station, so here I am to share knowledge with you! After amazing Richard of "Learn Electronics Repair" YT channel mentioned this place in his video, I checked you out (again) and ... what to say? This place is a treasure.
