[QUOTE="bamby, post: 8463879, member: 665588"] So a friend of mine has a P600x4 that stop working. The amplifier damage the IRF1404Z mosfets. Here are the photos [IMG]http://i1237.photobucket.com/albums/ff462/eehsnab1/1ABE7FB0-026E-42DF-9D6B-E52E621389B9_zpsjk0jsvoh.jpg[/IMG] [IMG]http://i1237.photobucket.com/albums/ff462/eehsnab1/11AAADCF-41C9-4112-B6C9-AB40FB71AEE4_zpsnj4bpy3u.jpg[/IMG] I dont know why this happen so i start to look around. When i remove the cover from the other mosfets notice that one IRF3415 and a IRF5210 had rust plus some resistors were covered in something that looks like battery acid( I dont know if the correct term is sulfate). He has a carwash and moves water and some wet things in his trunk maybe it got soke in water?.
