Once it get past the 888 and goes to tst, there is a period after then, when it should be lighting each channel. But nothing is lit. And nothing happens when i push either button, I think because it is still trying to light them in the test mode. If I wait for a minute, and push select button, the whole test sequence seems to start over with the numeric LEDs cycling thru again.
So I guess, my followup question is when should I push the select button for what you are saying in your last post?
