One last general question....... What are you telling your customers when a board is not fixible or like in my case with this board. What advice can i give. To sell the machine as defect? )

I just say I cannot fix it, case closed. Probably the best option is to dump it on Ebay, prices for such machines even broken are stupid high. Probably $500 for a broken one.....

 

[arghhh]

Did you check L8300?

 

[dukefawks]

It is eDP interface, only one data line has to have an issue and there is no image/backlight, nothing.

i didn´t check it anymore. I follow Duke´s advice. It´s better to not put my hands on this graphic chip and change it when chance is high to get a problem later on.
Therefore the customer will get this machine back.
