Here's how to check the codes.

 

If you don't want to change the LCD, this might help you. My LCD screen is black too, and there are a few times when I was able to read what was on it. The last time I was able to read it my car was out in the sun being baked at around 90ºF+. The sun was also shining on it through my front windows and I was able to read it for around 10 minutes or so. The first time I was able to read it almost the exact same scenario. You might be able to use that small time frame to diagnosis what is wrong with your A/C. Not sure if this is really the reason why I was able to read it though, but give it a try it's free.

 

If I recall correctly, the flashing AC light is an indication of a seized compressor. what you hear is the clutch engaging and when it senses too much torque required to turn the compressor the clutch disengages and flashes the AC light.
