Quoted from arolden:What are the voltages on the power driver board test points? Are they all in spec?
This is always a great place to start!
You have lost your +18V (TP8) Since the regulated +12V (TP3) is created from the +18V, fixing the 18V (Controlled Lamps) should also fix the +12V regulared (Switch Matrix). Your +12V Unregulated is also very low at TP1.
