Post by alvinquimbo on Mon Sep 08, 2014 4:25 pm

@ mga master, may problema  tong inaayos ko..nung under test pa ito di ulit nag on,naging standby lang sya..nang nacheck ko ok lang naman pala ang h_out,so hanap ako sa probs nito at ayon nakita B892 malapit sa 7812 na reg open po sya at naputol yung paa ng W574 na Zener diode..Tanong ko po anong value nitong W574 kasi wala sa Davao times at midland,so ginawa ko jumper nalang para magamit kasi di naman sya sira..Pagkatapos macheck lahat, start - up ko ang unit,umaandar naman kaso lang may problema sa vertical nya kasi magalaw at hindi stable,tapos ang audio nito ay humina kahit nasa full capacity na ang setting..ano po kaya probs nito?ok naman po lahat ng supply pati ang mga LV.
Ito po yung vert IC nya LA7840, tapos yung Audio nya ay CD5265CS, at ang chroma nya ay LA76814K may system con ito mga master at china board ito,iba lang pagdesign nya..sana matulungan nyo po ako master..salamat..

duda ako mahina ang supply mo master. subok ka nga magpalit ng mga capacitor. check na rin baka may problema ang anode cap master. tignan mo ang loob niya baka kinalawang na.

sis alvin sa video po yang IFT at may sound pa din dyan konting adjust at ibalik kaagad sa posisyon kung walang effect..


sis alvin ano yung galaw nya?parang sumasayaw baka may kulang sa supply.Yung main filter paki check na din at secondary filter na mataas ang boltahe..i hope makatulong yan..
