Have the older Minimax nt tsi 400.   Went out to check the equipment and the only light that was on was the "Pressure SW" light.  Had a good electrical storm go through and take out my WiFi router, electric dryer and I guess the pool heater.  I replaced the transformer, hoping for a cheap fix but it isn't fix it.   What do you think is bad....the main digital display #472100?  Thanks
