Had the same type of problem on my country coach it was a bad connection in the wiring harness going to the thermostat. My thermostat would go blank just like yours when I had several lights in use connected to the same harness. It could be a loose ground wire. Mine turned out to be a harness running next to the refrigerator and the heat had caused the connection to fail.
