880LM Flashes and does not open after a few times
I have a 880LM control Panel connected to a 8550W Garage Door opener for a bout a year. Recently, I noticed that when I hit the button on the Control Panel to open the garage door, it flashes the screen and does not open. I have to hit a few times until it opens and works normally. I have the 893LM remote and never had a problem with it.

Sounds like a wiring short at the wall-mounted control panel. Remove the control panel from the wall and check the wiring to the two screws. Are any of the wiring strands touching or near touching any of the control panel's circuit board solder joints?
