Don't boot, the moment has a high pressure, light flickering regularly. MJSservice manual download site
Boot moment can hear high pressure after the automatic shutdown, explain the power to start, the television into protection state, reason 1. Has fault or insufficient itself condition 2. MPU bus protection circuit malfunction with the actions or itself, for example, over voltage, over current, ABL/ACL, caused the circuit line field. MJSservice manual download site
U plate work boot test voltage 2.5 v. 3.3 v. 5 V.. V. 9 RESET moment is normal, measuring the U plate interface U1 (9) foot RELAY from 1 V to 0 V moment, explain MPU shutdown instructions, enter a state of protection, measurement Q854 C is 1.2 V (normal is 2.5 V) and IC1101 127 foot protection (foot) are linked together, Q854 B is extremely potential is constant, with over voltage, over current, line has nothing to do, can only be associated with the U plate, IC1101 measuring 127 feet to have leakage phenomenon, relationship with C1101 (127 feet) R1153. R1154 C1153 LC1115 eventually found LC1115 for leakage. MJSservice manual download site
