Their COFs IC part number is 8586-M. We can use the Bypass Modification method in LCD/LED Screen Panel Repair Guide, to do the troubleshooting and repairing. Refer to this part number COF IC testing point, found that the Y1 VGH (or as it is called "[/b]Von") voltage is missing! Normally it is about 24V. Different Panels have different voltages. As for this case, we can measure the Von testing point on the Source Driver board to know their exactly voltage. LED panel | |
