Tv Allwiew sasiu 11AK49-7

Recommended Posts

Sanatate ! La acest tv am gasit defect tranzistorul final linii .. Dupa inlocuire tv porneste dar cu o lumina alba laptoasa cu linii de cursa inversa .. iar SG903 care este intre G2 si masa  se lumineaza intermitent .ca un starter ..

 

Am refacut lipituri pe trafo linii si am schimbat placa TK , de pe un sasiu functional . dar defectul persista ..
