Re: Iiyama E511S blown SMT caps on PSU board

Yes, they're definitely caps. They're still recognisable as such plus they have C7 and C28 printed next to them on the PCB.

I realise there might be other problems, but as I got this monitor for free I thought it's worth a try.

Re: Iiyama E511S blown SMT caps on PSU board

As I don't know much about SMT, I've been reading up and here's a bit more info.

It looks like the caps are in a 1206 package and one side is connected to ground so maybe they're doing some decoupling? Would 0.1uF or 1uF be a reasonable value to try as a replacement?

Hi

I have a Iiyama E511S which switches on for a fraction of a second and during that time the picture looks ok. All the electrolytics on the PSU board look ok, but on the underside there are a couple of blown SMT caps (see picture). These caps are so burnt so I can't see what value they were.

Any ideas of what value these are likely to be? If it helps, the 8 pin chip next to the caps is an APM9435 P-Channel Enhancement Mode MOSFET. I've looked for a reference circuit which uses this chip but had no luck so far.

Thanks
