How To Test Topside Controls?

[pkillur]

I just replaced my circuit board which has been on the fritz for some time. I am dealing with a few issues and wondered if anyone had any ideas.

The first one is that when I plug the topside controls into the new board - it is just flat out dead. It was dead on the last board - but this isn't necessarily a good gauge I don't think.

The second thing is that my circuit is popping at the heater. But, I am 90% certain it's the heater and am in the process of getting a replacement element.

So my real question is - is there a way a novice-not-hot-tub-guy can test the topside controls? Like can I plug it into something else and see if it pops up with LCD controls or something?

Thanks,

Followup information:

Circuit board is a Spa-builders LX15, and the eprom is a 6.77.

Topside controls are LX15 6B2P it says W/R Alpha.

Could it be an EPROM mismatch? My eprom just says 6.77 but the one on the old board said Windriver alpha 6.77 ??
