I have a Venza spa tub made by Raindance.
I had cleaned the tube and use Bioclean to clean the pipes as the spa was shut down for 2 years ( drained and all lines and pumps evacuated of water) and grabbed a canister of Clean Start.
I filled the tub and followed directions and ran the tub, then drained and cleaned the tub and refilled the tub I had power off during draining and refill to check for any leaks which there were none.
I then after it sat for a half hour turned the pumps on and cycled through all 3 pumps then turned the pumps off to check the PH but when I went to turn it back on the control display was went dead.
I checked the GFI breaker and it was not tripped.
I then pulled all fuses and all tested good.
My control panel is backlit and I checked both bulbs and both were blown.
Checked Line voltage on both legs and that is OK.
I have an infinity spa pack part # 54585 with INF 107 wiring diagram, it has an addition panel for the third pump, which I can't see the part number, and a balboa 7 button control panel # 53189.
Is there a way to test the circuit board for voltage to the top control panel and if so how and what voltage.
