Question No display when turning ignition key on

Hi,
When I put the key in and turn the ignition on, the display goes off and I have to wiggle the handle bar or turn the ignition on/off again and again for it to work. Then only I can start the bike.

I had taken this video below several months ago. I showed it to SVC at that time, they checked everything but couldn't find any issues. They cleaned and greased things and checked fuses. Anyway it didnt happen until last day or two. This time it is not severe as the below. Just wiggling the handle bar worked this time.

This time it only happened once or twice and didn't think it was reoccurring.

One of my friend says, the issue lies in the power switch's end connection (attached), it has to be unplugged and clean if needed and plug it back.

Any idea on this issue?

It appears that the problem only begins when you hit the starter button. Is this correct?

First thing I would suspect is just a loose connection. Wiggling things and having them work usually points to that.

My guess would be a possible faulty battery or fuse. I watched the video and realize that your display goes off when you try to press the ignition switch. Ignition usually draws a larger current (compared to other components of the bike). My second guess would be what Louie Franco mentioned, a loose connection.

Something critical is losing power when you punch the starter button. Step one, check that battery terminals are tightened down.

The issue in the video happened several months ago. Service center checked fuses and battery connections, couldn't find anything but this never happened.

Last day I rode the bike for sometime, halted at a beach. When i tried to turn on the bike for going back, the display didn't come on after turning the ignition. Then I wiggled the handlebar and turned the key two three times and it came back on. This happened twice whenever I halted somewhere and tried to start again.

Sounds like you're able to duplicate the problem much easier now.
I'd take it back and have them look at it again.

To really find out the source, you need to do only one thing at a time.... Begin with the ignition switch (do not move the bars). If you turn the key 30 times and it never comes on, you know the switch itself is not the problem.

Then, turn the key on and reach below the ignition switch (below the key) and wiggle that wire harness. If it comes on, you found the problem!

My suspicions are in/near the wire harness that is connected to the key switch.

Does the bike ever power off while underway? If you start the bike and move the bars full left/right, does the dash ever go out?

I will try to isolate the issue, thank you for the pointers.
This issue never happens when it is running.
I'm wondering if washing the bike and water entering somewhere causing the problem. Although I don't have pressure wash.

Ok I'm sorry I'm late to the game on this one. I just saw this from a link in another thread. I can tell you exactly what's causing this, low voltage. My Majesty does the same thing if the battery is weak. What's happening is when you hit the starter the solenoid is making contact and the starter is drawing so much amperage that the battery voltage is dropping below that required to keep the display on.

I'd try another battery, chances are that will fix the problem. Or charge the one you have. You can see if thats the problem by throwing some jumper cables on it from a car battery. If it still does it then its bad connections to your own battery. If it doesn't, its low voltage.
