sir walang oscillation yang horizontal mo kaya ganyan lang nasusukat, yung sunog na R622 napalitan mo na ba? bili ka muna sa raon diagram para makita mo kung ano value nya, update mo ako pag napalitan mo

boss ano po ibig sabihin nito? (KV-14APX1 112387200 REPLACEMENT 2.04% ) sorry baguhan lng po

flatlander2john · « **Reply #8 on:** February 19, 2009, 05:44:48 PM »

thanks for the info boss..........try ko lng yong info

Tasyo · « **Reply #9 on:** February 19, 2009, 05:51:34 PM »

standard part number ng sony yan sir, focus ka doon sa value wag dyan sa part number every part number may corresponding part value sya
124494100 RESISTOR,CARBON; 680K 1/2W

yung 9 digit number is the part number for a 680K carbon resistor yung percentage naman sa dulo yan yung frequency kung gaano sya kadalas masira sa certain model

flatlander2john · « **Reply #10 on:** February 20, 2009, 01:29:16 PM »

boss ask lng po. may 284 volts po lalabas sa str 50112 pin 3? tnx

Tasyo · « **Reply #11 on:** February 20, 2009, 01:58:29 PM »

Sir yung 284 volts sa pin 3 is Unreg pa yan, pag check nyan is yung pin 123 ng STR mo ( 50115 ) like CBE ng transistor ngayon kung may short in any combination probably sira sya, now merong R2M yan sa secondary paki check sa cathode nya kung may 115 volts if ever meron malamang okey yung supply mo, pag OK check mo yung supply ng 20192 which I think 9 volts kung meron baka pwedi paki picture yung section ng 20192 kalimutan ko na kasi pin configuration nyan.

flatlander2john · « **Reply #12 on:** February 20, 2009, 02:17:22 PM »

boss walang lumalabas na voltahe sa pin 3 tapos yung Q503 walang 115 volts sa base.

flatlander2john · « **Reply #13 on:** February 20, 2009, 02:26:14 PM »

Q601 po pala.,

Tasyo · « **Reply #14 on:** February 20, 2009, 03:01:11 PM »

Meron bang B+ na 115 sir?

Yung Q601 yan ba yung TO220 type na kulay green/Black sa power supply, try mo tanggalin yan kasi by experience kahit wala yan tatakbo yung TV. filter lang sya. paki check mo na din 470K or 680K dyan sa power supply ( 1/2 watt ) madalas sirain yan.

flatlander2john · « **Reply #15 on:** February 20, 2009, 06:17:46 PM »

pinalitan ko na ng 470 k boss wala pa rin. may 115 volts sa b+, h out, pati sa regulator. yung r2m na diode ok yun may 115 volts.... di kaya flyback sira nito....?

Tasyo · « **Reply #16 on:** February 20, 2009, 07:24:25 PM »

mostly sir pag Flyback yung sira nag lload sa B+ yung symptoms, unless siguro kung open yung winding, anyway subukan mo actual, now kung may scope ka check mo kung may start up yung oscillation ng horizontal, mamaya baka di nag lalabas ng H-pulse yung 20192 mo.

flatlander2john · « **Reply #17 on:** February 21, 2009, 10:33:42 PM »

boss tinanggal ko na lng yung flyback. itinitest ko walang high volatge na lumalabas sa red wire na cap. ni check ko na rin yun junle ic walang 9 v din na supply.

Tasyo · « **Reply #18 on:** February 22, 2009, 08:36:27 AM »

focus ka muna sir sa jungle kaya wala kang high voltage kasi nga di tumatakbo jungle mo, paki post diagram kung meron ka mahirap kasi manghula

flatlander2john · « **Reply #19 on:** February 25, 2009, 09:47:00 AM »

boss ito na ang diagram sana maayos ko na to. thanks sa 2long.
