test mo ang inverter kong may output ba... gaya ng sabi ni geof79 yan ang backlight supply para mapailaw ang backlight = led man ito o CCFL

ok na to mga master una kung ginawa on ko yung LCD tv pag ka on ko kumuha ako ng flash light at inilawan ko yung screen niya may nakita akong image ..upon checking po the screen meron siyang image so.. i diagnose that the damage is back light,,,2nd step ko po eh binuksan ko yung Tv set meron akong nakita na apat na board .. isa yung power supply board ,at yung yung iba di ko alam ang tawag heheh main board lang alam ko tsaka yung supply .. sinisid ko yung supply muna to determine kung may mga supply yung board and i found out that there is no supply na dumadaloy sa board na papuntang backlight di ko alam kung ano tawag sa board na yun... yung ginawa ko sinuyod ko supply board kita ko . may open na isang resistor parang sunog .. di ko nga alam yung value eh.. pinalitan ko ng ibang value na resistor(trial and error ang ginawa ko kasi di ko alam yung value ng resistor).. and upon checking ulit ng supply meron na siyang output... (dapat sana papalitan kuna ng power supply yan kaso ginawa ko lang malay natin hehehe).... and .. pina andar kuna yung tv.. presto gumana .. inobserbahan ko siya ng ialang araw bago ko binalik sa may ari,,, naka tipid yung may ari ng pambili ng power supply ng kanyang LCD tv kasi ,,naayus yung supply ng tv niya hehehehe.. naka tsamba ...Smile
