Tv SAMSUNG LE40R81B
« on: September 12, 2011, 11:09:47 AM »
Am acest LCD care a avut cei 2 condensatori de pe bara de 5v umflati,i-am schimbat iar acum merge 20 secunde apoi se opreste ,iar merge 20 secunde si iarasi se opreste.
daca stie cineva cum se intra in service mode,sau un dump in pony prog ,i-asi fi recunoscator.

Ce am spus mai sus! Verificati lampile, invertoarele, tensiunile din secundar...

Am rezolvat problema, prin schimbarea MAIN BOARD cu una noua.
Multumesc celor doi moderatori pentru sfaturi .
