机型:L55C1-CUD 机芯：MS828H
故障现象：屏自检
维修与分析：上4K转接板机架试机呈灰屏状态，测量电压未发现明显故障。此板带图像增强模块6M60,接串口发现此处打印信息在不停的重复:
[CPU INFO] cpu opencreate instance at 345bb058 with private size 44 bytes at 345bb0a0
CPUIoctl – MDrv_CMD_CPU_QueryClock
[UTOPIA INFO] close moduleNames[38]: MODULE_CPU
[Ursa9]Write cmd:c1,5,f,0,8,70,0
[Ursa9]Send cmd:7, return:0

判断U1201(MST6M60)损坏，更好U1201试机老化故障排除.
