Sziasztok ! Fent nevezet projektoros tévével szenvedek Konvergencia beállítása nem megy Kapcsolási rajzot keresek de én nem találok aki tud rajzot hozzá segítsen Előre is köszönöm
Üdv Mesterek!
Hozzám került egy fenti típusú készülék, ami azt produkálja, hogy bekapcsolás után leáll és a LED 2 villanással figyelmeztet, hogy valami túláram van a B+ áramkörében. Én a hibakódok alapján ezt olvastam ki.
A bekapcsoláskor megjelenik a B+ rendesen és úgy 1-2 másodpercre indul a gép, majd leáll! A sorvégfoknál minden jónak tűnik. Akkor mi a baja a B+-al?
Mi lehet még a hiba oka?
Köszi
Valaki tudna-e segíteni, hogy a varistornak vezetnie kell vagy nem, mert az egyik tranzisztoron megvan a 300V a másik táptranzisztoron semmi, és még a 2sc2500 volt zárlatos annál amelyiknél nincs feszültség.
Segítségeteket előre is köszi
