Instrument not turning on.

The instrument will not turn on. The LCD is not displaying anything. The main power switch turns on, illuminates, and the two 10 A fuses on the back test fine. I've measured ~120 V AC on the terminal bar inside the back. I've tested all of the fuses I can find after removing covers, and all have continuity. I tested continuity of the on/off switch and it opens and closes fine. It reads 15 V AC at each of the switch posts though. Any suggestions would be appreciated.

I found the problem is the circuit board mounted transformer, "TR1" failed. Printed on the case is "X041067-0001", which I can't find any information for on the internet, and Leica has stopped supporting the EG 1160.
