Unhappy Replaced thermostat-not working now

Hi, I replaced my Honeywell thermostat with another Honeywell thermostat. Now nothing is turning on. I connected all wires the same as the old one but connected the blue C as well.

When I removed the green and white they were hard to remove.

I have removed the new Honeywell and out the old on and that isn't working either. Help please!

Did you turn off the power to the furnace/air conditioning BEFORE changing the thermostat? If not you might have blown the fuse in the furnace.

Also, the blue wire at the thermostat is not necessarily the C wire, you need to confirm that in the furnace.
