    [Fixed] Sanwa 29E31, Dead Chasis after coulours diminished then gone...

    Update: Q412 was changed for a new, just in case. D402 was good R456 open D401 was shorted on the right diode (between Q412 Col and D401 anode) after changing D401 and R456, power-on instantly blew R456 Verdict: something short in the horizontal deflection circuit
