    Olha só pessoal, está Tv chegou ligando, mas sem imagem, constatei defeito no barramento de leds, possuia 3 leds em curto, efetuei a troca das barras, ela começou a ligar aparecer o logo, e apagar o blacklight, fiz as medições na fonte, aparentemente estavam toda normais, porém um pouco baixas, os 5v, estavam com ~3,3v, os 12v, estavam ~11,38v e os 24v estavam com ~19,89v . Com isso, efetuei a troca da fonte, por uma nova, mas ela continua apresentando o defeito de dar o logo e apagar os leds, estou desconfiada da logica, pois se fecho curto com o pino on/of com o Pdim, ela liga, da imagem, porém quando vai colocar sinal digital ou um sinal HDMI, ela apaga os leds. Se alguém poder ajudar com esse defeito, agradeço muito, ta tirando meu sono.
