 Please remove the attachment from your post and instead post a link to the schematic if its already posted at badcaps.Otherwise post the schematic in the "Schematic requests ONLY!" forum so that other members can find it, then post a link to it from this thread.

 From an alternative MSI schematic, PU20 is MP2143DJ.

 Got a motorbike PCB that had 3 burned diodes.
 
 The smaller ones have the marking PJ78 GS1M
 And one larger one PJ78 GEX
 
 Can someone help me identify them so I can be able to replace with same or equivalent?
 Photos attached
 
 Apreciate !
 Thank you...

			by deep000My computer monitor ASUS VP249H stopped working, and smoke came out of it.
 I opened it and found that a voltage regulator had burned out.
 The problem is that I can't identify its reference.
 I searched online for schematics or photos of similar boards that people are selling, but without success (no schematics, bad quality of the board or lack of the reference when it's a good quality 😅).
 How can I find its reference, and do you think it's repairable?
 Monitor: Asus VP249H
 Board reference: 0171 - 2271 - 6083
 Thanks

			by cinkoxidHi guys,
 
 I wanted to test a DC adapter and I plugged it into my device and then I immediately smelled the cooked component. I cheked the adapter again and I discovered that it's not a DC but a 24V AC adapter 
 
 I took apart my tester and I think I found which component burned but I can't identify it for sure and I'm not sure where could i buy a replacement part which is the same or has similar features.
 I attached a few pictures of the component. I think it's a voltage regulator but some of the markings on the component are burned.
 
 Name of the...
