When turning on the TV, it stays on for a few seconds and turns off by itself, making a small noise from the speakers and turns on by itself again. | Defect in the 1.2v regulator (ic1103 - as1117), when placing a jumper on the d1103 diode (mbrs190t3g) the TV works, but the cause is a failure in the regulator | Ic1103 regulator replacement | CDS_DIAS / LED TECH |
