oo surplus nga ito...  hindi ko maasure kng tama ba tlga ang B+ nito? kasi nagmumula ang B+ ng secondary filter sa zener diode na 62V...    wala xang regulator ic maliban lang sa Zener nato... kaya nga masxadong complekado...   :'(  :'(  :'(  :'(  :'(

then  ang cathode terminal ng SCR dun kumukuha ng B+ ang secondary filter...   pagwla yung  wlang supply ang second filter & H-out...  in short  pagwla ang zener na nakakabit sa SCR no voltage reading.........   :)

SCR # = S6785G...   B+ nya= ?  meron nmn 80V across the zener  based on my checking voltage... ganito kasi ang design ng TV... kakaiba tlaga xa...  150V for Primary Cap.  of course operated 110V kasi...    & den + supply of dual primary caps. or split type going directly to the Cathode terminal of  zener diode 62V..   ang anode terminal nmn directly connected to the GATE terminal of SCR... & den SCR naka-konnektadu sa Secondary cap.

ang pinagtataka ko lng tlga wla tlaga xang main regulator maliban lng sa Zener na 62V...  dun dumadaan ang B+ na nare-read ng Tester ko...  ???  ???  ???  ???  ???

sir tdh7700 tnx..   ok na ang  tv set na to ....   

hahaizz sa wakas  natapos din


trouble found:

may open signal diode (D600) pala patungong  jungle  at may short na zener diode (D602 =  6.8V),  kaya pala hindi maka-oscilltae... drop into zero volt  yung other side ng power switch (DPDT). ...

ngayon ko lng napansin..  buti nalang nag-double check aku kanina..  (^_^)  nakaxamba tuloy


PERA na to.   ;D  ;D  ;D  ;D  ;D
