Sharp 14V-J100M Ayaw mag on ang 2nd power...Help

Post by st_richard04 on Sat Mar 17, 2012 11:40 am

Bakit po Kaya?

EEprom: 24CO1
System: IX2946CE
Jungle: X2933CE

Meron pong Ilaw yung 1st Power pula po kulay, meron pong standby Supply sa relay Papuntang B+ 144V, buo naman po ang switch, Meron po akong nasusukat na 4.8V sa Pin5,6 at 8 ng EEprom , Bakit po nung sinusukat ko ang pin 1 ng system ic meron akong naririnig na tunog ngayon po nawala napo.. ang lumalabas pong output sa smps ay 144V papuntang relay na diretso dapat sa B+ at 12V papunta siguro po ito sa system meron po ba kayong schematic nito? salamat sa help mga master..
1st Project 1st problem....he..he..he..

same problem din po ang naecounter ko sa sharp cinemaborg 21v-100m mga master.una ko po talga problema ay blurred picture lang na meron white multiple lines.ngtry ako palitan ang vertical IC na TDA8403K peron ganun parin.then kinabukasan power on ko uli ng tv pressing power button tact switch napansin ko na mdyo delay and click na naririnig ko yun ata yun relay pero mahina lang ang click nya then after few seconds click na naman ng mahina but blank and screen as in no sound.possible po kaya na nasira ang vertical ic na pinalit ko?nag sukat ako ng voltage sa secondary meron po ako nasukat na 150vdc from diode passing thru relay then connected to fbt b+ pero base on schematic dapat 115vdc lang ang b+ nya.ok lang po ba eto mga master?bakit po kaya mataas ang nilalabas na voltage ng secondary for b+?pero yung 12vdc normal as in exact voltage po nasusukat ko.Supply ng H-vcc ay galing sa 12volts then passes thru a regulator zener to produce 9.1volts with a parallel filter capacitor pero ngsukat ako ng voltage sa pin ng h-vcc ala po ako masukat.possible po kaya defective yung zener diode or yung capacitor?

sa jingle ic po masusukat ba ang horizontal drive?ilang voltage po ba dapat ang masusukat ko?anu ba dapat ang supply voltage para sa jingle ic?nagsukat din ako ng voltahe sa pin 2 ng horizontal drive tranformer pin 1 ay connected to collector of horizontal drive pero ala ako nasukat.disconnect ko yun series resistor from jungle ic connected sa base ng horizontal drive,may nasukat na akong 150vdc sa pin ng horizontal drive transformer.check ko transisto out of ckt ok naman.Isa pa napansin ko present yung 150vdc b+ sa fbt pero alang output yung lahat ng pins ng fbt tulad ng 24vdc for vertical supply,185vdc para sa crt at 12vdc para sa mga regulator ic kahit nakahang at hindi ang series resistor sa base ng horizontal drve tr.Sira na kaya ang fbt nito mga master?patulong naman po kinukulit na ako ng may ari huag naman sana bawiin o dalhin na sa iba..

master help nman, sharp 14v-j100 everytime na sw on ko ang main power, R701 or R702 (3.7, 7w) parati nasisira (open). at ang Q701 (D1884) parati nasisira (short).. test ko all primary supply component ok nman lahat. I replace this 2 component twice already but same result.. i even replaced IC 701 but no success.
Pero try ko 110v supply wla nman nangyayari sa R701 and Q701 hinde sla nsisira but no power indicator,but no 12v and B+ vol in secondary.
TIA

master noyzky7. palitan mo ulit ang tea2261 at na din ang main capacitor. sabi mo kasi nasisira pag naka 220. paki check na rin master sa value ng mga resistor. r701-2.7ohm 10w at r702-1.5ohm5w. yan kasi nakalagay sa diagram.
