It has a battery, that will need to be charged to 6.1 volts DC, in order to function properly.

Display would not turn on. I have replaced the battery and still no display. Do I need the charging cord to get it going?

The battery charger is only used to recharge a low battery.

If the console does not light up after pedaling. connect the battery charger to the machine and then plug it into an electrical outlet.
If the console powers up, your battery is low and needs to be charged.

Leave the battery charger connected to the machine for 24 to 48 hours to charge the battery.
It is okay though to use the machine with the battery charger connected.

If that still does not work, check over all main cables for loose connections or fraying. Especially those to the battery and to the console.

Verify that the speed sensor is 2mm (about a credit cards thickeness) from the speed disc on the alternator.

Please be sure to disconnect battery cables before adjusting speed sensor or touching any other electrical components.

The screen doesn't display a clear and legible display even when I'm peddeling

This sounds like a console issue. Your options are kind of thin on this one. I would suggest doing some research in order to find an option to have the electronics repaired in the console.

Stairmaster 3400 Exercise bike - how do I turn it on?

It should come on once you begin to pedal. If it is not coming on, then start by checking the voltage of your battery. Chances are it is low or even completely discharged.

Display won't light up when i start peddling, could it be the battery

It most definitely could be the battery. I would start with checking for at least 6 volts DC output from your battery.
