Argh...no...my PTSD is kicking in...I can LITERALLY hear those beeps in my head right now!  
Long beep, beep beep beep beep; This means it’s lost its programming!
Incidentally, both the ActiveDecor AND the newer NEXUS lifts are such a PITA!
I've been fighting with these lifts going on 6 years now!

I will give the manual to you, but it takes a bit of side-notes to cut through the fog.

Basically, you need to set the limits again.

• Switch to Program mode (towards rear)
  

• Clear Master Set Points
  • F, SET, F, ESC
    
  
  
• Run up to MAX height
  • Set upper limit (F, SET, UP, SET)
    
  
  
• Run down to bottom (in cabinet)
  • Set Home (F, SET, Home, SET)
    
  
  
• Run up to just clear cabinet
  • Set lower limit (F, SET, DOWN, SET)
    
  
  
• Put TV at normal viewing position - THIS MUST BE DONE; IT’S THE UP POSITION FOR SPYDER!
  
  • Set F1 point (F, SET, 1, SET)
    

• Switch to back to Run (towards front)
  

NOTE: you MUST perform ALL of these set points...even if the UP and NORMAL (F1) positions seem the same or else the functions will not work!

Any time I’ve had power OR HEAT issues, that brain fails. Oh, and you’ll blow the internal fuse if you run it too many times!

I'm attaching the Manual and Trouble-shooting flowchart; both of which aren't nearly as straight-forward as my "Digested Tried and Proven" steps above/

LMK if it helps!
