There are a couple possibilities:
1. If this is the first time you've started them for the season, one of the compressors might be seized up from sitting over the winter. In which case, new compressor required.
2. If you've just had the compressor serviced including recharging the system, it's possible that the system is simply overcharged. This will stop the compressor from working and giving you the same symptoms as above. If this is the case, you should have the service people come back with some guages and recover some of the refrigerant and the compressor should be fine.
3. If the unit has been sitting and there is a slow leak then there is not enough pressure in the system to allow it to run. The compressor will shut down if there is not enough pressure, but since you say there is a smell, i really doubt this is the case.
Most likely it's #1 or #2 above. If you haven't had it serviced recently, then yeah, it sounds like you're in need of a new compressor.

Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...

The blower motor kicks on when there has been a 24 volt control failure.
This usually means that a limit switch has tripped.
Most likely that would be a high temp limit switch or a rollout switch.
First, make sure the filters are clean. and the evap coil is clean. If eaither are dirty/clogged, it will partially block airflow, causing the furnace to overheat, causing the high temp limit to trip.
A rollout switch typically trips for three reasons.
1 flame rollout into the burner compartment due to poor airflow.
2 overheating af teh metal plate the rollout is mounted to, due to dirty, old, rusted components.
3 a bad limit switch.
If your unit has an LED light, count the flashes and it will hepl popint out the problem.
(locate the wiring diagram/flash code list, and correspond the flash count, with the code.)
First, check filters.

Check your thermostat wires to see if you have any of them which are bare and touching. If any are touching separate them and tape em up and try unit again. You have a direst short in your cooling portion of the unit.
