Hi guys;i have repaired VizioGV42L with no pic no back-light just relay clicking with white Vizio logo, by replacing U5 regulator with LO23 G1117, now it has Pic and sound but the Digital Tuner is not loading channels,but the Analog tuner is ok, i did check DU4 tuner regulator and input 3.3v, output 1.2v so it's good , any other place i have to check? thanks in advance,and happy Easter to everybody here.
