This is one for the SMD component gurus.
I need some help with this one please. I am looking to repair a relatively new motherboard that has suddenly stopped working and can't be RMA'd back to where it came from, as it's second hand. It was working on the bench and stopped working when it was installed into a case - a short-out could have occurred, but so far I've only seen the board for a quick look-over.
The symptoms are a brief 1/4 turn of the fans at power on then nothing. The motherboard is a Gigabyte GA890FXA UD-7 board (socket AM3, DDR3) and the board LEDS remain on '0 0' when powered up.
I've narrowed the search down to some SMD fuses that I think might be along the lines of 1210 or 1206 types, however, they are marked with an italic capital P and L 19 or 1517 and I am struggling to positively identify these components, as they don't correspond with information on the 1206 or 1210 data sheets, particularly the L marking. I've added a picture of the area of the board I'm talking about, so that you see the components I'm on about.
The component references on the board (e.g. F15, IF1) tells me that these are fuses, but which type exactly are they?
Thanks
