各位师傅，看看tp.mt5507.pb801d打印信息有什么问题?

enriquezhong

一台杂牌55寸网络电视，板号tp.mt5507.pb801 屏号st5461d04-2
故障原因: 有声音没有图像
各电压正常，可以开机关机，背灯led亮，测得屏压12伏正常 不知道是不是软件坏了
下面是开机打印信息：

更加奇怪的是，用rt809f 备份了emmc资料之后，电视的打印资料变成了下面的情况：

请教MTK是如何跑打印信息的，从来没成功过

被光亮能开关机，软件应该没问题。先查逻辑板升压没有，如果没有升压把逻辑板到屏的排线去掉，再量电压看是否恢复。若电压正常则是屏坏了，否则是逻辑板坏。
