malamang dumating na ang panahon para palitan mo na ang fbt mo pero try mo muna araruhin ng soldering iron lahat na ng parts matanda na yang tv na yan yung dito nga sa amin mga 5  years ng retired nasa bodega na lang ni lolo - sentimental value at ayaw ipagalaw. Palit ka na din ng mga ecaps. Check mo buhay pa components mo sa crt / cpt board. at kung humihinga pa chroma / system control ic; pagtapos mo mag-resolder, triple check mo na malinis baka may nag - short (lalo lumaki sira). Kandidato na rin picture tube for replacement (kandidato pa lang ha)  ;D ;D ;D
