EMMC is bad and is often found, this is a old chip. EMMC version is low.作者: lumina 时间: 2022-7-28 05:44
Is a 7 year old TV but if I can not read the chip, I have to put it in the garbage, main board is more expensive that the TV value. Thanks作者: Albano.Matos 时间: 2022-7-28 13:08

As a User: In the tv repair business, many times you can order those chips in newer versions, already preloaded with correct software on them, sometimes some friend in a forum post the software and indication of
a newer and equivalent IC, or the bulletin from brand support services....
Like the programmers themself, like TL866II --> 'turns' into T48, T56 will have an upgrade in the future, hopefully,
why not this IC. For sure, is up to you decide the way :-)
