Me problm din me sa Philips TV. Powers on for few seconds then shutdown. Ang pag-on long enough para mag light ang mga filaments sa CRT then off. Kailangan i-off yung power switch bago mai-power uli. Pero, me b+ sya pag naka standby but it won't power on. nagpalit na ako nga vert ic and low value resistor (na-open) feeding vert IC from flyback pero ganon pa rin. Appreciate your help. Thanks

normal lang ata yan sa ganyang modelo... main power switch yata ang tinutukoy nyu... kailangang pang turn off & turn on

yung channel up/down button nyan will be serve as your power switch
just press it

Thanks for the prompt replies. what i mean after initial power on and auto shutdown di na mai power uli kailangan switch off muna main switch.... will check then on dual caps na magkatabi as pointed out by sir ultrasonic. And also protection ckt as suggested by sir kag. Besides pwede bang temporary sub HOT nya BUT11AX with HOT gamit ng ibang TV brands a naka built in damper diode and shunt resistor? Will just solder BUT11ax when TV is back to norma operation (hopefully). thanks again bros and sis.

KGD SIR thanks much for confirming substitution of Philips HOT BUT11ax. will just do lil configuring perhaps kasi di parehas package types ng mga transistors anyway temporary lng naman ... just for testing purposes...

mga tol di ko pa na try i run ung philips tv na problema ko. alang TDA9302H dito. M tempted to sub AN5522 by Panasonic pero maliit resemblance nila except ung package baka lalalim ang diprensia. Ang kapareho nya ay TDA8172 pero just the same - di available. Guess istambay me for a while pabili na lang ako sa Maynila kung me papunta. Will update you regarding this Philips case. thanks.

I owe one from you and i'll update all of you.
