update lng po sanyo tv, napuntahan ko na po nku ang layo pala, eto po yung history nyan nanood daw sila ng movie almost 5 hours na yung unit na ginagamit, ayon biglang nawala at saka balik na sya sa standby, pinatingnan na daw nila ng ibang technician tapos di bumalik, may nakita akong paa ng piyesa sa harap ng HDT nya na putol na yung paa nalng ang nasa board ang alam ko capacitor peru di ko alam yung exact number parang may missing parts kasi kinalawang na yung piyesa eh. C436 yung location nya.

eto po yung model no: 21LX1
Chassis No: 21LX1-00
Chassis Series: Ac5-G121

eto po yung ginawa ko voltage reading b+ ok,
hang ang base ng HDT power on ala din
hang yung eeprom taz power on wala din
replace capacitor 1000/25 volts taz power on ayon nag oscillate cya in 3 seconds only, back to standby again.

mga master help po asan yung susunod kong gawin? tia

ibig sabihin ay ok ang b+ mo,ung horiz oscillation lang ang nawawala ganun ba?
napalitan mo na ung 100-25v ecap saka nagosc pero 3 seconds lang
ganun ba?
ung nawawalang ecap napalitan mo na ba?

opo yung hor,oscillation lng po ang nawawala, other voltages po ay present po yung eeprom, system nya ay buhay po. nung after i change capacitor 1000/25 volts yun may oscillation na, kasi dati wala standby lng pag on mo walang nagbago sa led ng standby kahit blink nlang wala but after i change e cap meron na kunting oscillation.

nakow wala ako schema nyan,pm mo si insan Lan at masinop sa schema un
may resistor yan (series connection) sa may 2ndary ng chopper mo, hagilapin mo un sis

cge sis try ko sila pm tanx update ko nlang dito ang susunod na pangyayari.

sis insider update lng po meron na syang oscillation kaso lng namamatay din blik din sa standby, meron na po 3 volts yung base ng h-out, tapos yung b+ nman nya nag slow down na, bali pag on exact 130volts, tapos pag blik nya ng standby mag step down din up to 100 volts nlang ang b+ nya? anu kay problema nito?

to sis pete saan bang banda yung diode na D1913 di ko maikta eh,

i alread change the b+ e caps ganun pa rin. help po mga master.
