Thanks for the quick response.
A little more info. I ordered a few of the 74HCT14's, should be here Saturday latest.
1: Found on 74HCT595 U05 pin 8 was buckled and bent inward, not very visible until board was out of cabinet. Could have been making contact for some time, don't know. No outputs that area are in use. Fixed, also substituted another chip, no change.
1: When powering up, the LED's remain off for several seconds (it's a lengthly program) until just before the LCD display comes active. Appears to be turned on by software, though only one LED should be on.
2: Added to the very end of the program, a circuit with a 1 second clock contact and a Dfun, CLRIO 2 LEDs, SetIO 1 LED, and Toggleio 2 LEDs. All the LEDs remain on.
3: Wrote a new program with 1 circuit - a 1 second clock and a Dfun that Toggleio all 8 LEDs, and they all FLASHED at one second.
Thoughts?? Still likely the 74HCT14, or possible some other chip? Chips are cheap could order a few others if a chance.
