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. |

Could you let us know what is the value of the pico fuse?
