Any chance you can point me to which capacitors and what fuse you replaced? I've got the same monitor with the same problem.

Thanks!

The caps are 470mF 25v. There are 5 of them, and if the monitor is in it's original condition they will be coloured brown, as opposed to other caps of the same value which are blue or black. I usually upgrade the caps to 105 degrees too, as this is a pretty common problem, and this seems to help. If I get chance tomorrow I will open one up and let you know which caps they are.

I have found the the capacitors that need to be replaced. But can someone tell me where the fuse is? Is this a SMT fuse or some kind in line fuse. Would REALLY apperciate if someone could tell me where the fuse is. THANKS,

The pico fuse is usually green or black. It looks like a resister but only 1 band which indicates the rating.

You should replace the caps anyways or you'll be replacing the fuse again.
