Thermastat went blank, Honeywell t8411R 1028Honeywell t8411R 1028

So far I have tried,
1. Checking the fuse and it's fine. Nothing wrong with it.
2. Checking the wiring in the thermastat, everything is still conected.
3. Water pan under the air conditioner is empty.
4. Tried to jump the G, R, and Y wires and nothing.
Any other suggestions or thoughts?
The airconditioning unit is made by Carrier although I am not sure what model.

1) I'm not sure he knows what he's doing / how to test.
... The repair man came out and blew 7 transformers trying to figure out the problem.
... the $500 a year was definately worth it.
2) $500 a year insurance ?

Anyway, sounds like Ken's got a heat pump with maybe a shorted solenoid on the reversing valve. How that would take out the transformer before the fuse beats me, though.
