Bonjour à vous, bien que votre article date, je me sens d'obligation de vous poser mon probleme lié au même afficheur et mêmes composantes. Je dois dire que vous avez été un peu veinard de tomber sur cet ic s302- 19, moi je n'en trouve pas ni celui ci ni le s302 - 11, j'ai pu comprendre que malgrés le s302-19, les ligne n'ont pas disparues, et vous avez été obligé de cours circuiter et utiliser une resistance sur avdd pour regler le probleme, est ce donc à dire que je peux m'en passer de s302? Et directement proceder au pontage avec la resistance?
=====================================
Hello, although your article is dated, I feel obliged to ask you about my problem related to the same display and the same components. I must say that you were a little lucky to come across this ic s302-19, I can't find any, neither this one nor the s302-11, I was able to understand that despite the s302-19, the lines n didn't disappear, and you had to circuit and use a resistor on avdd to solve the problem, does this mean that I can do without s302? And directly proceed to bridging with resistance?

How are you my mentor? Am trying to reduce the backlight current of a let tv. Motherboard Tp.V56.pb801. The led trice ic is sn51dp. I couldn't identity the iset pin and also the resistor whose value to increase to reduce current. Your help is always appreciated.

Great work. Well done.
Could you please let me know what is the component (BB801) which is between the inductor and diode in the topmost line of schematic of SN51DP shown above.
Thank you.

As diligent as ever. Most of us will have given up by the time vertical lines persist on the screen. Good lesson to newbies like me.
