You are a genious Carlos I have been dealing with this problem on and off for a year and you just solved the mystery. Phone booted right off after tapping it on the table. Thank you.

S4 won't turn on unless replacing battery, then turns off after two seconds?

This is the best solution to a problem that I have seen in the web for a long time. Worked in seconds. Thanks a lot.
I have tried all methods on this forum and the only one that functioned is the method posted by RudyGT. In certain situations the Power switch from the motherboard must be removed. After removing the switch you can do the following:
A new power switch can then be purchased online for a relatively low price.
Kind of an old thread, but thank you RudyGT.

Just to echo what's been said several times already, THANK YOU Carlos for posting your solution of tapping the phone on a table. I honestly did not expect it to work and had already gathered tools to disassemble the phone. I tapped it five times and the phone turned on. Thank you again! This is great to know. 
I was having the same problem...took the phone apart, tried to clean the on switch but nothing worked.
Finally I just ripped the on button off the plastic casing and used the "vol-down" +battery and that worked like a champ.

One of the famous power button got stuck problem
Here's the link for troubleshooting and solutions. You might need some simple electrical skills.

I didn't think that'd work but I decided to try it anyway. After about a couple of seconds of tapping it lightly on it's side it sprung back into life. Thank You again!
I joined just so i could thank you for sharing this info, you saved me a lot of aggravation. All i had to do was quickly and repetively click the button for several seconds to see a little bit of gunk fall out and now the phone and I are happy again 
Like others I joined to say thank you!! I'm out of town and just knew I would be without my phone until I was able to get to a verizon store or back home. The tapping did the trick.
Tip: Be patient with the tapping. It took me over 30 minutes of tapping to finally get it to work. I was just about to quit and go buy some tools to take the phone apart and then like magic, those last few taps did the trick.

THANK YOU SO SO SO MUCH! With just 5 light taps on the table, it worked for me! <3
Like others I joined to say thank you!! I disassembled S4, blow to remove dust, then I started to pres power button until phone turn on. Thank you again.
Thank you, this has been very helpful indeed.
Just wanted to share my story in the hopes that it helps anyone who has tried this thread's suggestions with limited success:
When this issue first happened to me I came across this message board. The cause made sense to me and the trick of laying phone on its side and lightly tapping worked (sometimes). So I thought, I should just take it to a professional, to clean or replace the power switch, and I'll be fine.
Imagine my surprise when not one, but two independent repair guys tell me it's absolutely not the power button (the first cleaned it, the second tried replacing it). Neither of them could tell me the underlying issue, they thought it could be firmware which made absolutely no sense to me.
Rather than doing a factory reset, I went to a third technician and asked him to dig deeper. Turns out the problem was that two resistors leading to the power switch were blown. He replaced those resistors and now the phone works normally again. I paid £30 but it was well worth it.

I suspected the power button, but i didn't think to clean it. Thank you this just saved me some solder work.
