so  jf  nga.. meron  na yang RBG unbalance  protector..  kaya focus  ka din sa C board.... be sure buo ang RGB tranny driver, Resist at diodes jan...

i highly recommend  pa rin na ayusin ang pag balance ng Screen at Focus adj.  para makapagpatuloy  kau sa troubleshooting  mu....
note:  yung  orig  na tube at yoke gamitin mu.."  para  kong maperfect mu  man ang calibration..  fixed na yan..

mahirap  kasi  kong sa ibang  tube tapos  naayos  mu ang calibrating. paglipat mu sa tube ng tumer.. shut-off na  naman  ;D  balik sa simula


ang mga nabanggit sa taas ay dadaanan mu pag buo ang mga sumusunod:

PSU (stabled napalitan na si secondary cap), system con(nagreresponds at gumagana ang protection ckt), eeprom(reflash/Palitan), jungle(buo ang Hvcc at nagbibigay pa rin ng H-Pulse), at ang huli sa pinaka common sa lahat ang VERT. dapat buong buo yan.. (from dual supply, & Vert sync pulse)



salamat po master, ittry ko po, ano pong pwede pamalit sa dalawang chip diode sa c board? kasi sunog po at pinalitan ko ng iba, chip diode din pero hindi ko alam kung ano ang number.

It seems na nakakaubos ng buhok ito.
Dont lose hope, maaring walang problema ang main circuitry pero ang protection ang pumapalya.
Find some diodes na nakakonekta sa 180 volts, HOT collector, 24 volts, vertical output, RGB output. Dyan lagi nakalagay ang protection circuit, you can hang them one by one and see what will happen , wag kalimutang ibalik paghinang kung walang pagbabago. Im talking about some crystal diodes some are zener.


salamat po, ittry ko po.
