  分析检修:首先升级软件无效。检查倍频板(5800-H72310-OP20,双芯片),未发现明显故障。找了一块单芯片的倍频板(5800-H16800-OP10)装上开机,图像正常,老化不到5分钟,图像闪烁后黑屏,以为是新装上的倍频板有问题,又更换一块,还是一样问题。想起该机配液晶屏的代码有两种:一种是-01,一种是-03。于是进工厂模式修改屏参,改后故障排除

创维55E780U(8K94机芯)液晶彩电开机不定时出现屏上一半为七彩屏,一半花屏


  拆机检查,发现倍频板螺丝没有固定,将螺丝固定后故障排除,但过了一段时间故障再现,更换屏驱动线无效,最后将倍频板与主板的连线排插加锡补焊后故障排除。

感谢大师分享经验,不过这都在售后技术网站看过了:这机芯的常见问题七彩屏或者叫烧机模式的,测量倍频板D22压降正常直接刷这个程序试试,技术网站给的是命令升级的我这个是自考的烧写方便。
