How do I take these cabinet doors off?

[bobtskutter]

Hello FOG, please help.

My wife and I bought this sideboard from a local charity shop.
It's from the 1960's and generally in good condition.  I need to remove / renew the shellac coating in the cupboards, but I'm not sure how to remove the doors.
The bottom hinge is secured to the bottom of the cabinet with two screws and has a pin into the bottom of the door.
The top hinge is secured to the top of the door with two screws and has a pin into a plate at the top of the cabinet.  That plate is attached to the cabinet with one screw and also acts as a stop to prevent the door opening too far.

How do I take the door off?
I could just remove all the screws and see what happens, but I'm not sure.

Edit- add pictures

Thanks
Bob

You should find screws at the top and bottom of each door.  Removing all four screws should release the door.  At that point you should be able to access the screws that hold the hinge in place. 

It may be easier to accomplish this by laying the cabinet down on its back.  You will have easier access to the lower hinge screws that way.

Note:  I can only see two screws per hinge.  If there is a third screw, then remove the screws from the cabinet first (both top and bottom).

Remove screws from bottom hinge on the cabinet, remove screws from top of door on top hinge, slide door forward.

Those are known as "knife hinges". As the others have said, they are a bit labor intensive to remove, but the point is that they virtually disappear when closed.

This installation video should help.

All, thank you very much for your help.
I removed the screws from the top and bottom of the door but it refused to slide off the hinges.  I can see how it should slide off (now I know what to look for) but I suspect after 60yrs the wood has shrunk and clamped the hinge very tightly.  I tried pulling it, tapping it with a mallet, using a quick clamp to apply pressure and I even shouted at it but nothing worked.
I can get the little DTS400 in the cupboard with the door in place but it would be much easier to remove the door.  Never mind.

Regards
Bob
