Re: LG Flatron L17NT-A no power
U801 is 3.3v low dropout Voltage regulator,the centre pin being Gnd,the lefthand one Input and the other one Output.They do go faulty and could be causing your problem.You can test it if you lift the two outside pins and then with nothing connected to the Board,you could apply a Dc Voltage greater than 3.3 v between input and Ground,and then measure the output, if that is the 3.3v it is supposed to give then, my best guess would be that the Logic Board is faulty. If you have a 3.3v fixed regulator then you could change it, and see what happens !!
