Does anyone have the so-called tech bulletin for the power-supply varistor modification?? I have 4 dead cabinets that I would like to repair them if possible. Thanks

I doubt that your 4 units are in need of the varistor modification. A symptom of this problem is that the unit would come back to life if you unplugged the power cord for approx five minutes. The modification was xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx if I remember correctly (maybe someone else will chime in - I havent seen that TSB in many many years and don't know if I could locate it).

The open forum is not for tech level programming and repairs. Please use the installer forum for this.
