Re: LG Smart Tv No picture but has flickering horizontal lines.PLEASE HELP

ohh thanks for the info i was going to heat the chip only, guess i will first use a hairdryer to heat up whole motherboard and then i will heat the chip with a heat gun and luckily i have temperature measuring device in my house will use it to monitor temperature on chip, by the way how much temperature chip needs to reflow 230C? or higher? and thanks for
