The door opens just fine from either the remotes or wall control, but not the keyless entry.

HELP HELP HELP!!!
I tired adjusting the plastic screws that adjust the speed of the door (up and down screws on the side of the opener)
when i try to close it...it goes completely down...and then the door opens automatically now...
What you can do to set that DOWN limit is open the door and then get into position where you can adjust that limit switch. Close the door - as soon as it reaches the fully closed position, slightly (1/8-turn or so) adjust the limit switch opposite of the direction the little arrow points. This should stop the door from opening back up and will also tell the motor that the current door position is fully closed.
You may have to do this a couple times to get it set exactly the way you want it, so there's no gap between the bottom of the door and the garage floor. I've seen on older models that if the door stops slightly short of its mark, adjusting the limit switch in the desired direction a little at a time will cause the motor to kick on momentarily and will move the door in the desired direction. You'll get it to the point you want it without going through a complete door opening/closing cycle. You can adjust the door open position by doing the same thing with the other limit switch. When you're done adjusting, run the door through several complete opening/closing cycles to be sure it functions properly - no blinking light at the end of either track.
Also, as you may have discovered, the light blinking is a visual indication that the door exceeded its maximum position - the motor cutoff kicked in and stopped pulling/pushing the door. You cleared the problem as you adjusted the limit switches. I hope this helps - have a great Thanksgiving!
