When I power on my old monitor Samsung Syncmaster 740n, it needs needs 2-3 min to power on. When it turns on, it works fine.
What can be wrong with it and if it possible how to fix it?

Almost inevitably this will be due to failing capacitors in the power supply section of your monitor. These can 'dry out' (the commonly used term) and become less effective, with the usual symptoms being some mix of:
This is a common problem with electronics, particularly from a certain time where poor quality control and/or penny-pinching in the supply chain caused a large rise in such failures around 10-15 years ago.
The problem is that the symptoms usually only appear well outside of any warranty period, and often even after manufacturer support for a model has ended.
Happily, this is usually an easy enough thing to fix. Any competent electronic repair shop should be able to diagnose and replace the capacitors. Although they are only a few pennies each, the labour costs may mean this is uneconomic though, given the costs of a new, likely superior, monitor.
If you have a soldering iron and a sense of adventure you may want to try this yourself though. There exist many self-help guides on the internet (www.badcaps.net is a good place to start), and indeed I had much success doing this myself when my printer started playing up a couple of years ago.
