Thanks very much for your response, sorry it has taken me so long to answer. I'm attaching photos. I tested and there is power coming into the circuit board. I replaced the 30A fuse. There is an inline 20A that seems to be fine. But still nothing happening. So, I guess this means I'm stuck with replacing? The unit is old--21 years--so I can't complain. Should I replace the whole box, which is pretty pricey, or is there another option? Thanks again for the advice, much appreciated.

I have an older Leisure Bay spa that was working perfectly until we got a major power surge that fried several of our electronics--basically everything that was on, or in some kind of standby mode at the time. The spa is not coming on at all now (no display reading, no sounds, etc.), though I've checked the power source. Any suggestions on what to check or replace first? The control box is model WH-S2-CCAJ and it's 110V. Thanks.
