je tente de depanner un TV LCD Toshiba de 130 cm

je me debrouille en electronique mais c'est ma premiere TV ecran plat



https://drive.google.com/file/d/0B5-yLpPXDiO7R0JyVmxXRy1mTlU/view?usp=sharing

on peut trouver ces cartes sur ebay mais elles sont d'occasion et donc  
pas garanties


est ce que il serait suffisant de changer les 2 condos chimiques ?




par moment l'ecran est parfait avec tout le contraste et la lumiere
et par moment la lumiere est tres faible et l'image fait penser aux  
premiers ecrans LCD (avec plein de remanence)

encore une chose

des transformateurs ?

est ce que cela pourrait etre un simple faux contact ?

en tous cas la piste du retroeclairage est une piste interessante

Une goutte de soudure avait remis en vie l'inverter, bien sur, plus de  




changer.
