meron kasing iba na may N.C pin. "No connection" pero pag kinabit mo na ang bagong crt socket ay nako connect ito na hindi dapat. nasasali kaya blackout ang nangyayari. mas maganda dyan kong gamitin mong guide iyong orig. eksamenin mo ang bawat pin. kung anong pin ang dapat hindi naka connect sa board ay wag mo iyong i connect. putulin kong maaari. Meron din naman sitwasyon na misleading ang pin orientation kaya double check na lang

Lipat na rin natin ito dito para madaling mabasa at hindi agad matabunan   lol! 

Modifying STRS-X70X na maglagay ng external tranny sa labas as serve as a Regulator.. 
yung pin1 at pin 3 lang ang e cut niyo... iwan ang pin2 nakaconnect pa rin sa mainboard/chassis board kasi yan ang internal common ground ng STRS



then rewire nlng according sa pin config ng tranny gagamitin.. 

para hindi mawala kayo sa pag operaha ay sundan niyo lang ang mga nasa larawan..

ito ang internal & pin config ng STR-SX70X as your guide

ito naman ang Actual pic config niya  ^_^

Note: lahat ng nakaviolent pin ay iwan nakaconnect din sa board

ito naman ang Actual Footage ng finish surgery ^_^


ito naman ang successful bypass kasi my standby at Power na ^_^ 




About naman sa Tranny na ilalagay kahit anong Tranny ang ilagay niyo bastat NPN lang ay gagana yan... pero syempre piliin niyo yung mga common na QReg na gnagamit sa TV
 like: C2498, C5038, C3552, C4429, C4458, D1884, D5299, & etc.. pati nga ang Qreg ng mga China board ay swak dyan....  ^_^ 

ang process ng Modification na ito ay gaya din ng pag ooperaha natin sa mga STK73907 or IX1791CE
ang pinagkaiba lang ay NPN tranny ito at FET or MOSFET naman yung sa mga IX at STK...

kung may extra naman kayong STRS na ok ang internal tranny pero sira naman ang voltage regulation niya like low B+ or high B+ o minsan naman ay Palyado.. nag O auto shutdown & etc... ay pwede niyong din yung gamitin gaya nito  ^_^

follow niyo lang ang desire voltage na kailangan ng orihinal na supply ng tv. halimbawa sa B+. 



dapat iyong B+ supply ng Universal ang ikabit mo sa B+ ng TV. adjust na lang sa trimmer kung kinukulang. iyong mga low voltage supply gaya ng 25V, 16V at 5V naman ang gamitin sa mga low voltage ng kailangan ng TV. Hindi naman necessary gamitin lahat. piliin niyo lang ang kailangan talaga ng TV
