kung tube cra nyan...pagtinaasan mo ng g2 or screen voltage hindi yan mag retrace line....depende sa model ng sony...pag gdr,gmr,str series cya , minsan pag abl ang problem no picture with sound...blanking cya pro blink ng blink lang ang ilaw sa harap...to confirm kung tube talaga....hang mo yung RGB sa tube mo at sukatan mo votahe nila,dapat halos parehas lang cla,or dapat nakahang yung tatlong RGB mismo sa tube,then idikit mo saglit to ground isaisa,dapat sobrang maliwanag bawat isa yan sa tuwing kinakabit mo sa ground...saltik lang...screen voltage dapat 500-600v pag malakas pa tube mo....malalaman u naman yan pagmalakas pa tube mo pagtinaasan mo ng g2 or creen voltage mag white lines yan....maganda kung bigay mo rin yung exact model ng sony tv mo....

check mo rin rgb input sa C board,dapat magkaparehas voltage nila...if parehas ,nasa C board problem mo,check mo RGB output voltage nila dapat halos magkapareha lang...pero dapat nakahang RGB mo sa tube
