uu nmn.. mas madali nlng yan kasi my oscillation khit saglit...

pg ganyan ang scenario be sure agad na ok ang vert. section nyu.. then sunod nyu ang jungle area lalot ang 47/50v kasi isa yan sa common na sakit ng chassis na yan... ang c board din suyod ka rin jan.. pki double check din ng B+ supply nyu kng buo pa rin ba.. 47uf/160...

good sign yan sis kasi my improvement na... atleast may naaaninag ka na... in this tym alam mong nag oosciallate na ang FBT... iyang rgb color ay suspected ko ay cause iyan ng lamat ng deagussing

check mu ngayon ts ang Video supply mo sa C board 180v at resolder ka na rin sa parteng iyan

nope iba iyan.. ang tinutukoy kng video supply ay ang supply ng RGB gun ng Picstube mo.. 150-180V iyan.. madali lang namang sundan.. hanapin lang ang ecap na placment number 2413 = 22uf/160V ang + terminal nyan ay ang Video supply mo.. dadalhin ka nyan hanggang sa C board at RGB gun (KR,KG & KB)... check mu kng presence pa rin ang supply jan at compare din kng equal pa ba...

nag direct sub ka na ba ng filter ecaps?

try mu nga idisable pa isa isa ang mga RGB guns ?
then e-load mo ulit pa isa isa.. resolder na rin sa buong C board bago ka ulit bumalik pa balik sa jungle
