This is Janet from MiTwell, a Portwell subsidiary.
We found an issue at our customer ‘s end which seems to be caused by the LVDS IC from NXP and now need to solve it urgently as this issue has been pending and our customer is now very upset and impatient.
It is regarding to your eDP to LVDS IC, PTN3460IBS.
After multiple tests, we learned that the issue is caused by the IC and found that the board soldered with some of your IC were found white-screen issue while some were not.
With further analysis, we found that the IC with and without issues are with different serial numbers:
The IC without issues:
PTN3460IBS
S3R082.
1 02
ZSD1512
The IC with issues:
PTN3460IBS
S3R083.
1 01
ZSD1515
Could you please let us know, the difference of these to batches as soon as possible for us to do further analysis and find the solution for our customer’s issue?
We have been striving to solve this issue.
Your fast response would be appreciated!
Thank you.
Hi Litao,
I would recommend to remove both ICs and submit them to local QA team (through the distributor the parts were purchased from) to re-test these two different date code ICs.
Best regards,
Tomas
