trebuie sa porneasca cu o multitudine de telecomenzi,lg mai vechi,philips,pilot 909 1690 etc,megavizion,nei,daewoo,euroclor,teletech,etc daca nici una din aceste nu le ave-ti,atunci incercati un dump si poate ave-ti norocul sa fie vre-o unul cu child lok inactiv,sau poate o memorie goala misca ceva

Salutare...am un pt 90, sursa ok, final linii ok, tens driver ok, driver bun etc

nu imi iasa din stby  , la led nu se cunoaste nimic, adica intensitatea luminoasa nu scade....posibil taste blocate?

cum pot porni fara telecomanda???

 

multumesc

Aveti 8v pe STV224...(pin 17;45)?!? Exista SCL-SDA?!?! Exista ON  de la procesor? Ati schimbat condi de filtraj( CD01/47uf) de pe alimentare trafo dreiver?! Cu baza final linii decuplata ,apar impulsuri linii?! Cu ea cuplata ,aveti o tensiune negativa in baza?!
