You may have made an error in your efforts. Recheck your work.
Having said that, there is no substitute for understanding the circuit, why it works, what it's supposed to do, and so on. Armed with that knowledge you should actually be able to design such a circuit. Then you look at the diagram and see where the parts are and what the voltages should be. Then you go in and make measurements, looking for a reading that doesn't make sense. You are now on top of the problem. Standard troubleshooting techniques.
Don't expect someone to say 'oh I had that exact problem and solved it by escolining the framistam.' Not that this couldn't happen, of course...
