ang sanhi niyan master ay mahina na ang tube. may leak na transistor driver at change value resistor. pwede din ang supply ng video

wala ka nang ihihinang sa board. idadagdag mo lang iyang tatlong resistor as a bleeder load. connect mo sa 200v video source ang isang paa at sa magkabilaan RGB guns naman ang isa. ang value depende yan sa kong gaano na kahina ang tube. puede mo simula sa 1.8M ang value hanggang sa umabot ka sa 680K.

ang alam ko dyan master maiiba ang value sa gun na weak na talaga. halimbawa yung red. dapat yan yung may pinakamababa ang vaue na lalagyan mo. gaya nung nasa picture na sample
