Hi Sam, Pls post a video for P4.8 indore panal, for how could i repair module with continue showed red light line (approx 6-8 lamp) in display after plug in power. thnks in advance.
What should be the soldering iron and air temperature in 3.9mm pixel repair. I have one more question. The Pixel was plugged in while it was being repaired and I think it shorted out and the entire row turned white. What should I do?
It should be that the row power supply is burned due to live operation, usually the row power supply is RT5958 or 4953; one RT5958 controls the power supply of 8 rows of lamp beads, and one 4953 controls the power supply of 2 rows of lamp beads.
If you can see the drive ic the face. You will see a lot of 4953. Have 1pcs of 4953 are broken. But which one need to check . Normally 1pcs 4953 control 2 row. So if the problem on number 13 and 14 row. Should be number 7 the 4953 need to change.
Thank you so much for this knowledgeable video

请问那么多芯片，你怎么知道是哪一个坏掉了呢？
每个都有自己的作用，根据不同现象判断出那个不良，无非就是驱动芯片(5153,5020,5124,5252....)控制芯片(74hc245)行译码(74hc138)行电源芯片(4953)
