  前些天接修一台联想LS2033wD显示器三无,开机检查电源正常,数字板上的5V,3.3V等电压也正常,但指示灯不亮,按开关机键也不起作用。数字板板号:492A01AG1300R01,屏LTM200KT12。怀颖数据问题,在网上下了个数据写上也一样,以为主芯片NT68661UFG QFP坏了,在网上购了块NT68661UFG QFP换上,故障不变,想到可能是网上下载的数据有问题,于是在淘宝上买了个数据写上就正常了。附上数据,同行遇到避免少走弯路。

在线刷校验到23%提示错。拆芯片后刷,一次成功直接亮机。感谢楼主,多谢分享。

拆下刷机,在线不好使,写入成功,但是检验失败,25LXXX,拆这个,焊编程器简易座上,用楼主程序一次成功,复焊板上,开机正常,我这显示器是用户家停电了,来电就三无,谢谢大家!
