VIZIO TV E470-AO Will not turn on, There is no 12 volts on pins present.
I have checked the pin out voltages on the power board and I have no 12 volt output. Can someone please help me back trace the 12 volt path so I can determine what has failed on the board. This is my first attempt at doing this so I am a real rookie novice but very willing to learn. 

Thank you in advance,
Ralph

Szovjet Rubin panelek elcserélendők, kéri valaki, valamelyiket?
Üdv minden tanyalakónak! Van nekem -és én már nem fogom használni...hi- néhány Color-Star, azaz Rubin TV panelem. Itt a képeken éppen nyolc db.-ot lehet ezekből látni. Ha valaki kéri, gyűjti, írja meg, mit ad nekem bármelyikért és már viheti is. Árat nem tudok mondani, várom az ajándék ajánlatokat. A képek nagyobb méretben is (rákattintással) megnézhetőek.
Megint egy régi Videoton.TS 3351
Sziasztok! Megint egy régi Videoton akadt a kezembe,mégpedig egy TS3351 tip.fakávás TV.Lomtalanításvolt és nekem adták.Azt mondta a gazda hogy már vagy 15 éve nem használják csak ott állt letakarva, mert bedöglött.És tényleg, szinte pormentes a belseje.A készüléket csatlakoztattam a hálózatra de a lemágnesezőn kívül egyéb hangja nem volt,illetve a készenléti ,mikor kihúztam villant.A táp kondikat kicseréltem de nincs változás.Kimértem a tranyókat jók.A sor és a táp tranyó szintén jó.Kicseréltem a TEA 2029-et,és annyit változott hogy a sor tranyó helyére bekötött 60w izzó villan és ugyanakkor egy halk kattanás hallatszik a tv-ből.Sajnos nem tudom beazonosítani hogy honnan.Van valkine valami ötlete hogyan tovább? Köszi Belfi!
