How can I tell which component on a pcb is the fuse?

Hi
I am looking at an lcd inverter and trying to work out which part I need to replace to get it working again. Problem is that all the components look the same. I am trying to work out which is the fuse, but all the components on the pcb are coloured, rectangular devices with numbers on, and no indication as to which is a fuse.

Is there a way to tell which is the fuse, and an easy way to recognise transistors and other components?

Does anyone know a good site for help with this?
Thanks

I'm not sure what you are looking at, but those rectangular things are most likely integrated circuits. And they are probably surface soldered to the board.

The fuse should be marked on the board with some kind of identifier such as "F1" or F-1 or something like that. If it is a serviceable part at all it will be cylindrical with a wire or lead out each end and go through the board. If you have no components that go thru the board then you have an SMT type board and you are not equipped to fix this at home unless you are very talented and experienced in surface soldering.

Companies spend lots of money on such equipment (millions) so you are probably not going to be able to change any fuses. AND there are SMT fuses as well. There are so many different ways these could be identified someone with experience like me would have to spend considerable time looking at it to figure it out.

Is it really worth the aggravation to fix yourself? Perhaps taking it to a shop, if it is worth it at all.
