接修一三星显示器,型号见标题,开盖发现主芯片烧包,读25X40内数据已通不过效验,淘了块二手板上机蓝灯开关正常,点不亮,刷了几个数据有的能开关机,有点干脆蓝灯也点不亮,屏为M190MWWW4,板型见下连接,原机数据809提示已损坏就不传了,24C16没动过,这机是不是要动24才行呀?求修过的师傅上传数据指点思路,谢谢

二手主板?你能确认全一样的?板是好的?
你还不如直接找块通用板点一下屏,先确认一下屏的好坏,再作打算。

这款机型有不同的屏,屏不一样数据也不一样,所以买板时一定要看屏买。

通用板点屏,809作信号源,强光手电简伺候能看到信号变化,龙腾屏背光是6排线,难道是3组背光?不知怎么接线就没改挂高压板,屏问题不大吧,本想弄块二手板省事,看来麻烦了。后又找了台一样型号的机,看生产时期是2015/03,已改为RTD方案,读出的数据见下,只是待修机生产日期是2014/03 Version No:MP01,应该还在保修期吧,这机型号还真真多
