Jon, at the moment we are in solar minimum, there are very few surface features to see. At the very least when viewing visually the sun should look like an orange. You should see the speckled appearance of the disc.
Are you burping the pressure tuner before use ?.
Next time you use it the first thing you should do is use a low power eyepiece,and concentrate on focusing the sun to a sharp disc.
Then gradually tune the etalon until you see some detail, you should feel some resistance in the tuner as you tighten it up.
If you don't see any detail visit this site and do a site search on your dilemma. It could be a faulty tuner( "O" rings?) or a cloudy blocking filter.

I hope this has been a help.
