The revA version of the NHD-4.3-480272EF-ASXN#-T TFT now uses a Sitronix ST7282T2 controller that replaced the  Himax HX8257-A controller on the original vesion of the 4.3" TFTs. 

Please see the Engineering change notice on our website that was sent out to customers purchasing this display:

The image below shows the RGB timing characteristics for this display. 

Please see the current datasheet for more details:

Even we have worked on NHD-C12864WC-FSW-FBW-3V3 for a bit to create a new design. However, I'd suggest buying a better one for custom design if cost is not a problem. I am in the process of buying one, but confused between many, can you suggest me some best ones?

TFTs / Display NHD-4.3-480272EF-ASXN#-T and NHD-4.3-480272EF-ASXN#-T revA

We manufacture a device based on a RPi 3 Model B and we use the display NHD-4.3-480272EF-ASXN#-T.  Recently we have updated kernel to version 4.18.20-v7+ and in some devices we are experiencing display problems... After some investigation we saw that our devices were using 2 different revisions of the display:

NHD-4.3-480272EF-ASXN#-T and NHD-4.3-480272EF-ASXN#-T revA

Both of them purchased to Mouser with the same product reference in their catalog.

The current configuration in the file /boot/config.txt regarding HDMI is:

hdmi_mode= 87

hdmi timings is:

<h_active_pixels>   480
<h_sync_polarity>   0
<h_front_porch>      1
<h_sync_pulse>      41
<h_back_porch>      2
<v_active_lines>   272   
<v_sync_polarity>   0
<v_front_porch>      2
<v_sync_pulse>      10
<v_back_porch>      2
<v_sync_offset_a>   0
<v_sync_offset_b>   0
<pixel_rep>         0
<frame_rate>      60
<interlaced>      0
<pixel_freq>      9009000
<aspect_ratio>      3

and regarding colors, we have:


we also have (but I am not sure if related...)

Please, have you any idea to overcome this problem??

Can you provide the proper init commands for this LCD.  I've used other board with the same controller, but I can't seem to get anything to display on here even using the ALL POINTS ON command.

Hi Duwaar,

Yes, the max current output from the regulator should be sufficient, as this display requires a max of 1mA to operate.
The backlights shouldn't be powered with the 5V pin either, as its rated for 3.3V operation only.

Since you are still seeing low voltages across Vout and V1-V5, this indicates the voltage-booster circuit isn't properly activating.
Can you verify that you have changed the pin locations from your setup on the Arduino to match with the code I've provided? 
Code: [Select]
*               Pinout on Arduino Uno               *

#define RES 8   //Reset signal
#define CS  9   //Chip select signal
#define RS 10   //Register select signal
#define SC 11   //Serial clock signal
#define SI 12   //Serial data signal

Can you also clarify if you are using electrolytic capacitors, and provide an image of your setup if so? Or are you utilizing non-polarized capacitors?

Perhaps you may also be interested our NHD-PCB12832A1Z; a PCB specifically designed with the necessary capacitors and a current-limiting resistor on-board for this display. This would be an ideal part to use simultaneously for optimal prototyping.
