Sziasztok! Eljött az idő, hogy csövet cseréljek. Fűtést megnéztem, 6V effektív. A rossz cső még bennevan, rövidrezártam a fűtéselőtétet, így 7V-ot kap, amíg rá nem szánom magam a cserére. Mérve a zöldhöz képest a kék 20%-os, kb, 400mikroA. Viszont ha bekapcsolom a TV-t akkor egy percig talán tökéletes, majd szépen átmegy zöldbe a kép. Tehát az ellenkezőjét csinálja mint egy normális cső, ami ha leült járatás után helyreáll. Ez pont a járatástól esne vissza? Mit gondoltok mehet bele a nokia cső a Thomson helyére? Én megpróbálom, de aki tett már EHJ helyére ECF-et, szívesen fogadok tapasztnyalatot :) Köszi! Üdv: Pityesz
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

IMPORTANT! Choose a forum topic name that is eloquent, as closely as possible to what you are writing about. One possible good name is eg: ORION LCD PT26S chassis 17MB12-2, the power does not start It is not enough to eg "LG LCD TV" or "HP laptop" and the like. The title should not contain uninteresting, irrelevant information either! Incorrectly named topics will be suspended and then deleted after 48 hours! While suspended, others will not be able to post until you correct the address. The incorrect address can be subsequently corrected (within 48 hours) by clicking on the "Edit" tab.

JVC LT32HG20E tv-hez firmware-t keresek ( Vestel 17MB61-2 main).
Kedves mindenki! Az eredeti mainboard picit megégett, vettem helyette másikat, más FW-el. Kérdés, hogy tudnám ezt frissíteni kép nélkül, illetve van-e valakinek hozzá firmware-je? Gugli nem segített. Köszönöm.
