Hi
We have been using this product in mass production. The product in the picture of attached OK can be used, but the back 25 pin of the upper board of the product in the attached picture NG is the screen backlight control pin. There is a deviation between the output voltage and the set voltage, which is 100% bad, please confirm the reason?
The date code of the two physical products is different. Will the different date code affect the parameters and functions of the product?
Thank you
