mga master p help po ung TV na inaayos ko

unang sira nya dead set po..

pinalitan ko po mga pyesa na:

1.)STR 5741
2.)horizontal transistor
3.)lahat po ng electrolitic n capacitor maliit at malaki
4.)lahat po ng resistors at diode s primary power supply
5.)checking po ng mga pyesa

pgktpos ng lahat ng ginawa ko sinaksak ko po. .

pumutok ung STR talsik nga po ung part ng STR

ano p po kya possible n sira nito?

hindi po ako master,,newbie din ako katulad mo.. check mo lng lahat ng parts sa psu pati mylar...

hehe..ok po pno po b mg check ng mylar?

brucetech · « **Reply #8 on:** January 07, 2012, 09:49:18 PM »

set vom sa x10k...parang electrolytic lng din..

ok po salamat s tulong.. update ko po kau ulit kpg ngwa ko n mga pnggwa nyo.

pa sub, check muna maayos mga parts sa supply sis bago isaksak,tanggalin muna load ng b+

BUMBLEBEE · « **Reply #11 on:** January 08, 2012, 07:12:01 AM »

abang sa update.. nasa primary ang problem... bago ka mag-trouble sa PSU,, gumamit ka ng 110volts paalala lang kung auto volts yung unit..

RhUNhA · « **Reply #12 on:** January 08, 2012, 07:32:20 AM »

mas ok kung tanggalin sa board ang parts at i check ng mabuti suyurin mo ang psu....

brucetech · « **Reply #13 on:** January 08, 2012, 06:40:17 PM »

ano na ang status nito ts?

kleinrio · « **Reply #14 on:** January 09, 2012, 08:21:29 AM »

mga master update po ncheck ko n po... pero wala prin ako mahanap na sirang pyesa.....

ano po b dahilan kung bkit pumutok ung STR?

ditchie · « **Reply #17 on:** January 10, 2012, 03:00:23 PM »

use bulb load sa fuse. kung magtesting para iwas kaboom at magic smoke.

may nakagawa na ba nian bukod sayo...chek mo kung may mga nachange value na...

chek rectifier diode...

check big ecaps...

check open resistor...

check zener at primary connected to low voltage vcc of str

wala p po ako palang gumalaw nito

ncheck ko n po rectifier diode = ok

big ecaps = ok

resistor = no open

cge po focus ako sa str
