sony kv-21jdr1 waving picture
« on: May 27, 2010, 10:55:28 AM »
tanong lang po kung ano ang pwedeng sanhi ng waving picture.
wala kasi sa akin ang set,pinagawa kasi ng hipag ko tv nila sa iba tech, malayo kasi lugar nila kaya di ako pwede.
unang trouble nagbliblink daw ang picture ang gawa ng technician pinalitan ang pot para sa  screen,nawala naman daw ang kundap ng picture pero nagwewave parin ang picture,ngayon gusto daw palitan ng tech ang fbt.
sa experience ko kasi pwedeng nawala ang kundap ng picture kasi binabaan nya ang voltage ng screeen at yung wave ng picture palagay ko capacitor sa b+ or yung ecap sa may boost.
ano sa palagay nyo mga master
