Hi Friends! as you know today we will talk about LCD/LED panel voltages missing problems, for example, 12v, 3.3v, AVDD Voltages, VGL Voltages, VGH Voltages Missing Problems. In the last post I have already told about panel testing points, Panel testing voltages with details You can read that article Click Here To go. So, below I have mentioned a table you can check your panel and see there what is your penal’s problem and solve it.
So In This post will get a complete explanation of How Missing Volages creates the problem in LCD/LED Screen Panel. In the below table you can see every missing voltage and it’s a problem that it will create. So that you can give the required voltages on that point.
Missing Voltages | Problem |
---|---|
12v | White Display |
3.3v | White Display |
HVDD Voltages | White Display or Picture Problem |
AVDD Voltages | White Display-Negetive Picture |
VGL Voltages | White/Blue Display With Lines |
VCOM Voltages | Negetive Picture-Brigtness Dim |
DVDD Voltages | White Display-Blinking Picture |
VGA Voltages | No Picture |
VGL Voltages | Slow Picture |
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
Missing Voltages | Problem |
---|---|
12v | White Display |
3.3v | White Display |
HVDD Voltages | White Display or Picture Problem |
AVDD Voltages | White Display-Negative Picture |
VGL Voltages | White/Blue Display With Lines |
VCOM Voltages | Negative Picture-Brightness Dim |
DVDD Voltages | White Display-Blinking Picture |
VGA Voltages | No Picture |
VGL Voltages | Slow Picture |
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.
NO. | Testing Point | Min Voltages | Max Voltages |
---|---|---|---|
1 | VGH | 25v | 32v |
2 | VON | 25v | 32v |
3 | VGON | 25v | 32v |
4 | VDDG | 25v | 32v |
5 | VGL | -5 | -10 |
6 | VOFF | -5 | -10 |
7 | VGOFF | -5 | -10 |
8 | VEEG | -5 | -10 |
9 | VDD | 3.3v | 3.3v |
10 | VLOGIC | 3.3v | 3.3v |
11 | VDDD | 3.3v | 3.3v |
12 | DVDD | 3.3v | 3.3v |
13 | VDA | 12v | 14v |
14 | AVDD | 12v | 14v |
15 | VDDA | 12v | 14v |
16 | VSOURCE | 12v | 14v |
17 | HAVDD | 8v | 9v |
