Probleme la tv Nokia 7184

Recommended Posts

La Nokia model 7184 top, dupa o functionare de cateva minute, imaginea trece in alb negru cu ,,purici ,,cu tenta de violet si verde.Peste imagine apare suprapusa o perdea in tabla de sah ce se deplaseaza pe diagonala. Am inlocuit CI codor decodor video VCU2136 fara rezultat. Inainte de aparitia problemei pe imagine, au fost probleme cu proc.de baleiaj, DPU 2553 S, pe care l-am inlocuit cu DPU 2553 simplu.Sa fie asta una din cauze?.Mai nou am scos matricea de pe placa, am schimbat c-urile electrolitice din calea comuna si deasemeni integratele, dar defectul persista.Ma poate ajuta careva cu o idee?Multumesc mult.
