Mga master baka meron kayo schematic diagram nito Sharp 21V-j100m pashare naman po.ginagwa ko po kasi etong tv na eto ang problema po nya ay blurred picture as in malabong malabo then meron multiple horizontal white lines pero ok ang sound.ngtry na ako magpalit ng vertical TA8403K at mga ecaps along this vertical ic pero ganun parin.checked vertical supply 24volts ok naman.anu pa kaya ang puede ko gawin.pahelp naman mga master..

oo mga master ipost ko talga actual image ng defect nya kaso sa ngayon ala din ako camera pa yung cel ko alang camera tapos yung camera kong canon sira nabasag ang screen mdyo mahal din magpagawa.try ko ipost dito yun pero may ako problema mga master sa ginagawa ko kaso mgsusukat sana ako ng mga voltahe pa tinanggal ko yung connector ng degaussing coil kasi komportable ko mailabas ng mabuti ang board,ng ipower on yun tv magpush ng power button delay ang naririnig kong click na parang relay ata yun tapos click uli pero ayaw ng power up ang unit pero meron ilaw ang power indicator nya.nagiba na tuloy ang sira.ala naman ako iba pinalitan o tinanggal maliban lng ang connector ng degaussing colil.may epekto ba yun mga master?ngtry ako mgsukat ng supply papuntang vertical ic pero ala ako masukat.possible kaya may problema ang vertical ic na pinalit ko mga master?til now ginagawa ko parin..

gudlak sis... aware lng tau na dhil malabo/blurred ang image nyan.. mlaman corroded na ang CPT socket mo.. or maybe focus pot ng FBT.


regarding sa scanning line
kng ganito na eencounter mu...

try to adjust screen pot. baka mwala ang mga linings.

kng ayaw nmn try direct sub ng video caps mu.. 10uf/250v ang value at double check sa c board.

sori, now ko lng npansin.. naging no oscillation pala
check for possible loose contact or crack board.
pki double check na rin ng dual filter caps mu.. bka pumapalya..
kng duda sa bagong vert ic.. try to replace a another one

baka nga master parang no oscillation ang problema.ngtry ako magsukat ng voltahe for H-vcc pero ala ako masukat expected ko 9.1v base sa mapa pero zero volt ang nasukat ko.possible ba master ultrasonic na yun dahilan kaya no oscillation or no horiz.pulse?Tama po ba ang aking pagkakaintindi na pag alang narecieve na h.pulse ang horizontal drive transistor at HOT hindi rin magfufunction ang fbt para magkaroon ng secondary ouput voltage anf fbt?kailangan po ba sabay sila ng b+ at horizontal output pulse para gumana ang flyback po?.

yapz tama ang pgkakaintindi mo. yan ang isa sa pnakamalapit na dhilan kng bakit wla kaung oscillation.. kng SMD quad type nga ang system con at jungle nito... mukhang L2 chassis nga ito... check mu lng maiigi sis.. pwde shorted zener diode lng ito sa 12V/9V rail

tungkol nmn dito. kng L2 chassis nga ito at hndi tau ngkakamali.. ang normal operation nito ay dpat my 150V kau sa secondary caps C751at nkaabang lagi ang supply nyu sa Hvcc 9.2V na nnggagaling sa Chopper transfo "gawin mong reference ang C755.

then 0V sa isa pang secondary cap (C604) dhil di pa gumagana ang power relay... yan dpat ang standby mode mo sis...

pg sa normal saturation/oscillation mode nmng ng unit mo.. mgkiclick dpat ang relay.. mgkakaroon ng V supply sa C604. iyong 150V babagsak into vrms 115V ata.. di ko na maalala.. paki double check mu nlng

paedit ulit sis... tungkol nga pala dito.. as long na wla kaung gnalaw sa vertcal side.. disregard mu nlng muna.. except kng ng resolder kau.. at tinamaan nyu.. c502.. mraming ndadali jan techncian at isa na ang mga ojt's ko..

btw sori tlga di ko msxadong narereview ang mga post ko at post nyu.. bz lng tlga sa work

salamat master reply..update ko lang pala sa gingawa ko na eto.base sa mapa trace ko ang voltage present sa chopper o sa smps secondary output.pagpower on click ang relay tapos measure ko voltage sa diode D751 150V present going to fbt b+.check voltage bet.D752 at C755 12Volts present din.check ko rin expected 12volts bet.D604 at D605 pero zero volt ang nameasure.this 12volt supply goes to H.vcc sa jungle ic na niregulate naman ng zener diode D631 at C633.Try ko hang ang pin ng H.vcc sa jungle at nagsukat ulit ako ng voltahe bet. d31 at c633 meron na ako nasukat na 9.2volts which is the exact voltage needed for H.vcc supply.Suspek ko possible na meron short either sa jungle ic or ibang line connected sa circuit.Try ko check resistance bet.hvcc pin sa jungle at ground pin ng ic zero resistance sya as in shorted.Confirm ba master ultrasonic na meron talga internal short ang jungle IX2933CE na eto kng zero resistance?kaya ba alang oscillation o horiz.pulse output ang nangyari?pls advise po...

kng my zero ohm reading ang Hvcc to Gnd pin ng Jungle ay jungle na nga ang salarin jan... direct sub ka na rin ng zener (D631) before ka mgpalit ng new Chrome/Jungle ic for safety precaution, bka kasi di na rin yan ngreregulate ng matino... sempre SOP ang R634.

btw kng wla kang mkita na IX2933CE.. pwede mong pamalit jan ang IX2429, KA2163 at TA1201AN

gudlak sis... at mgkape ka na (^_^

thanks master ultrasonic ok ang tv,nagpalit nga ako ng Jungle IC IX2933CE at zener diode 631..kapehan na sana kaso may isa pa problema master ala naman sound.perfect sana ng picture display kaso ala talga sound.nagana naman ang volume control pero no effect..check ako ng supply sa audio amplifer IC351 TDA7056A present at tama naman ang voltage.check din ako ng SIF vcc sa jungle ic present naman ang 9volts.check ko rin yung mute driver transistor Q351 at series resistor R355 pero ok naman.meron akong naririnig na mahinang mahina sound at ugong sa speaker.Hindi kaya kailangan sa servie mode lang ayusin eto?hindi ko rin kasi alam panu ang service mode nito mga master patulong naman po para maibigay ko na sa may ari at kapehan na tyo..+1 mga pala sa inyo lahat mga master..

agreed! sa mga ganyang cases... after testing ng unit, dapat mo tlaga ididischarge ang dalawang 160v na capacitor. to avoid damaging the the chroma.. biktima na ako nito.. kaya take cautions nalang sa next time... lalot nat mag autoprotect sya..
