1. ung crt socket po pwedeng palitin na
2. ung picture tube kailangan erejuvinate kasi mahina na
3. pwedeng flyback mo mahina na
4. my problema sa high voltage area

On my opinion

nakakaapekto kaya yung parang punit sa pcb board kasi merong caps na nakakabit doon eh parang napunit ata yung contact na nadikit doon sa board pero naka-attach parin yung capacitor doon sa parang green contact

eto po yung board nung speaker.

resolder mo muna yan sir then test mo nrin ang mga speaker mo if ok pa..

mga master pahelp naman po. nasira kasi yung charger ko. ayaw na magcharge. wala nang supply na dumadating dun sa dulo ng charger. tinest ko yung voltage nya nung sinaksak ko wala nang supply. di na rin umiilaw yung LED ng charger. chineck ko yung mga connection sa board at wires okay naman. ano pa bang ibang solution dito wala naman sunog na pyesa sa board. Maraming Salamat sa tutulong.

gusto ko lang po matuto magrepair kaya pinost ko na rin po dito.

madali nlng yan sir check mo muna ung 24v mo papunta ng vertical IC mo galing sa flyback ang supply na un dadaan un ng diode then fusiible resistor bka open ung resistor mo or shorted ang diode mo o sira ANG IC mo sa vertical..
