The code for 5 flashes is RPM sensor or motor overload. The RPM sensor is a small printed circuit board just in front of the motor.

29 years is along run on an opener. Personally I would replace it and not spend any money trying to repair it. You can try and find a control panel, or buy a new opener for $200.00 at HD. you can leave track in place replace rollers from new opener box.

Sounds like loose connections. Unplug, remove the cover and be sure all connections are tight and secure. While doing this be sure there are no burnt connections or burns on the PCB. Replace cover, plug in and it should be OK.

The code it is flashing is "RPM sensor or motor overload." It is not a door sensor problem. The RPM sensor is a small circuit board just in front of the motor.

Lift-master 2000SDR remotes will open but not close garage door. Same problem with all clickers and even those programmed into the cars. What could this be and better yet, how do I fix it?

Lift-Master 2000SDR opener. Opener generally works fine from the remotes. However, first time in the morning in cooler weather, it will start to close and the reverse and the lights blink. I have checked the senors - appear to be aligned properly. I have lubed the gear and used garage door spray on the rollers and hinges at the proper places. To close the door when this happens, I have to hold the wall button.

Lift-Master garage door opener stopped working

The motor will probably need rewinding.
Professional job. Don't forget to take the condensor with the motor.
Or alternatively, if money isn't a problem,, get somebody out to look at it.
There ya go:)

Xantrex 2412 will not open my Chamberlain Lift Master Prof. door

That must be a pretty big door opener. Problem is probably the motor's starting current draw. Most AC induction motors pull 5 to 7 times their rated running current when starting from a dead stop. (about 7,820 watts) That's much more than the surge capacity of a 2.4 Kw inverter. Sounds like you need a bigger inverter or a smaller door motor.
