So I had a problem on this board before, but with the help of fellow users got it working, it has been washing fine since then!
But this week a slug crawled on the PCB (yeah...) and both got toasted. I can see that R120 is dead but that's the easy part.
The slug was lodged near D15-D7, touching the transformer. I suspect the transformer died since it burned a hole on the PCB itself (only on one leg). I wanted to remove it to test and clean the PCB around that area but the transformer started to disintegrate as it was very brittle.
Now the thing is I don't know much about electronics, and when I search for the numbers on top of it I can't find anything. Can someone help me find a replacement?
Also, what should or could I also test along that area/circuitry?

hi,
first, i really don't see hole in smps transformer area, maybe you're mistaking the cuts that separate hot and cold areas
if the tnansformer is dead, you will never find him, if you are brave open it, undo the coils, note all like diameter and no of turns etcaetere, i mean make an identical transformer, but that's for the experienced people. maybe it's realistic to change the board or if you vahe space, put another supply with same voltage output levels ( maybe 2 voltages are made, but you can tell from filtering caps on smps transformer output).
I doubt he was gone, i'd guess control circuit or surrounding components are dead, but if his 'disintegrate ', no way of repair him, maybe find some other tranformer body same size and 'clone' the disintegrated one
but after remaking the transformer you still have to deal with control IC and around him
