Re: logik 32 inch LC32DIGB20
i dont have another camera sorry and its like somthngs over heating or gettin to hot because it turns on and stays on for like 5 min and the time gets shorter everytime i try and turn it on to were it just turns on and flickers and turns off but if you think its a baclight fault could i unplug the inverter board and see if the tv will stay on for longer than 5 min with this unpluged what do you thinkLeave a comment:
