SONY KV-V16MF2 intermittent distorted picture
« on: April 11, 2011, 10:40:48 PM »
Patulong po mga masters sa Sony..

modelo ito na nabili from saudi. Ang trouble nya.. may time na pag-on mo may black na gustong tumakip sa halos half ng raster na nag ii-start sa right side ng picture tube, na parang tooth ng lagare (medyo malalaki nga lang), itim na itim cya na parang carbon paper cya..na talagang di mo makikita ang video.
gumagalaw cya na para bang nang-iinis sa viewer..starting sa right side going to leftside..then babalik uli sa right. and my time na wala naman. at my time na tatakpan nya 100percent ng raster..
this happens on both audio video mode and broadcast mode..
wala naman effect sa sound.

Parts used:
strs6707
la7845
tda8366
may auto game ito using remote
model ito na pwede mo baguhin ang aspect ratio ng screen from 4:3 to wide screen.

Advise skin ng mga tech dito e capacitors dw sa hor section..nag palit me direct subs.. ganoon pa din.
alam ko na baka nga cap ang salarin dito.. pro aling cap kaya? at saan lugar.. normal lahat ang B+..at wala ka mapapansin na fluctations sa mga reading ng mga dc supplies..
baka may naka-enkwentro na sa inyo ng ganitong nakakainis na trouble..
wla din akong schema nito..
pls help..
