I purchased this LCD (HY-280_262k) from you sometime ago and am having trouble with displaying anything on the screen. I am able to get the SD card to work but the screen displays bright white every time. It is currently connected to an Arduino Uno R3. Is there any sample code, schematic, and/or any reference material you can send me to get it to work with the Arduino Uno?

Thanks

Hi friend;
Please visit our wiki about TFT LCD http://www.geeetech.com/wiki/index.php/2.8%22TFT_LCD
It will help you to get it work.

Thank you for the reference material; however, I am still unable to display anything on screen. I still only get a bright white screen. I followed the pin mappings below and ensure that there are no shorts in my connections. Also, I tried both demo programs from the newer library UTFT and the older library ITDB02_Graph16 with no luck. The initializing statement used was UTFT myGLCD(TFT01_24_16,19,18,17,16) for the newer UTFT library and ITDB02 myGLCD(19,18,17,16,TFT01_24) for the older ITDB02_Graph16 library. What am I still doing wrong?

LEDA -> 5V
LEDK -> GND
VCC -> 5V
RD -> 3.3V
GND -> GND
DB0->DB5 to D8->D13
DB6->A0
DB7->A1
DB10->DB17 to D0->D7
RSET->A2
CS->A3
WR->A4
RS->A5

Hi friend,
Please try to use this library with Initializing statement UTFT myGLCD(ILI9320,19,18,17,16) to see if it could works.

Unfortunately, I still get the white screen with the 2.4TFTlibrary. I tried all the examples with no luck. Any other suggestions? Or is it possible I got a defective module?

Thanks

Hi friend,
I found that it should be the main problem that the 2.8 TFT modules our supplier provided us recently include ILI9320 controller instead of ILI9325.
Please try to use this UTFT library that I have modified with the initializing statment UTFT myGLCD(ILI9320,19,18,17,16).
We will try to contact the creator of UTF library to support it in future.

I still get the same results with the modified UTFT library. I tried all examples of the modified UTFT library with the initialization statement UTFT myGLCD(ILI9320,19,18,17,16) but I still get the white screen.

Hi friend,
