Panel DC to DC Voltages
Hi Friends! In this tutorial, we will teach you all about LCD/LED Screen panel dc to dc circuit and voltages testing points on the panel in an easy way, I will tell you how to check panel voltages in an easy way. I have mentioned a table below you can check all the voltages according to this table, for example, AVDD, VGH, VGL, VDD, Hvdd and much more.
Panel Voltages Missing Problems
Please see the below table if you are getting the problem from these all problems then see the second table and also see what voltages are missing. You should have all voltages on the DC to DC IC Voltages Test points according to this table, if you are getting all the voltages, then you have to diagnose other things, it’s not DC to DC IC Problem. Otherwise, if you are not seeing all the voltages according to the table then you can give correct voltages to the point by the table.
