I have removed and installed a new battery into Iphone 6S and booted up, everything worked well,tested all and it went fine. After an hour screen went black, the phone still works but the screen is black. Tried different screen but it still gives me the same black screen while the phone is working fine.

That is typically caused by damage to the backlight circuit. It will work for a brief moment and then fade to black.

It’s very important to always disconnect the battery before disconnecting/reconnecting the screen assembly. The issue is that the LCD connector has pins that have high voltages (i.e. the backlight is ~20V) and ground in very close proximity. When you fumble around trying to line up the connector plug to the receptacle, you can short out the voltage rail and cause damage to the components in the backlight circuit. If you’re lucky, then only a backlight filter is damaged but other times, the entire circuit could be affected. Either way, this type of repair requires micro-soldering and isn’t really a DIY repair.

To test for this, plug your device into a charger or an iTunes enabled computer. Then shine a bright flashlight on the screen. If you can see a dim image, then the backlight circuit has been damaged. If you can’t see an image at all, then it may be the LCD circuit that is damaged.

You can connect the original, cracked screen to confirm this. If the original screen has the backlight on, then the replacement screen has an issue. If the original screen also doesn't show the backlight, then the backlight circuit is blown.

If iTunes doesn’t recognized the device than the problem is more than just a screen or backlight issue.

You'll have to find a repair shop that does micro-soldering. It's usually a straightforward repair.

I have what seems to be a similar problem with my iPhone 6S, and coincidentally just posted a question about it.  I find that with mine, if I disconnect the battery and then reconnect it, the backlight will come back on for a short time, but then it will go black again.  I can verify that it is a backlight problem by shining a flashlight on the screen.  Have you tried disconnecting / reconnecting the battery to see if it comes back on?   I’ve read several posts that suggest a bad backlight is due to a fuse being blown, but it doesn’t seem like it would work for a while after disconnecting/reconnecting the battery if it were really a fuse.   I might try putting back in the original factory battery and seeing if that helps, but I’m trying to see if I can find any additional information before going through that effort.
