Screen Will not turn on.

Great to hear. If it worked can you please upvote the answer that helped you so others can benefit too?

Hello, does anybody find any solution on black screen or no turn on after pressing power on button?

Yes; DO a factory reset. 
I.e. press and hold power button for 10 seconds.
For some reason I had to do this twice before the screen came back on

Hello, well i try power button for 10s few times, but nothing happened - everytime black screen blink twice, and then black screen furthermore... :(

attached videoclip from doing power button for long time - but nothing good happened :)

Same problem. 530 won't turn on after charging. Occasionally ten second hold works, sometimes have to hook it up to computer and do different things. All of which are not appropriate when your buddies are waiting to go for a ride. Seems Garmin makes products that will you what size b.m. you will have in three days but you can't turn the thing on. Did they assign an intern to handle the on/off programming? Terrible. And you can't get them on the phone without wasting an afternoon. No mas!

mine did the same thing tonight. Did you have any luck getting the problem corrected?

Hello, no - i send last week to Garmin service, and next day they send me new device. problem with screen.

Same result here. It’s a known problem on early 530s where the screen detaches from a circuit board. Customer service was great and sent me a replacement at no cost after receiving return of original unit.
