Re: Help needed with fried SWMPS

Hi. I'm chasing a fault on a Ring RSC612 as well. Mine lights up and does all the diagnostics but won't charge, even though it has no fault codes. Can anyone tell me what the two To-220 packaged semiconductors are on the corner of the board opposite the power supply corner. The heat sinks are soldered directly on the printed circuit track. I can't make out any numbers on them. Thanks.
