1.44 Color TFT Display issues

by tenicho on Thu Jun 15, 2017 12:27 pm

Hi,

I order the Adafruit 1.44" Color TFT with Micro SD Socket display https://www.adafruit.com/product/2088 on 5/22/2017. The order number is 1451805-7678739256.
I followed the tutorial that is recommended to use in the product description. When I run the graphicstest code I get a white screen. I commented out the wrong initializer and uncomment the correct one.

Here is a picture of the display after putting power to it and running code. It goes white as soon as I put power to it.
I'm pretty sure the product is bad.

I commented out the wrong initializer and uncomment the correct one.

So you made this change?
Code: Select all | TOGGLE FULL SIZE
// Use this initializer if you're using a 1.8" TFT
//tft.initR(INITR_BLACKTAB);   // initialize a ST7735S chip, black tab

// Use this initializer (uncomment) if you're using a 1.44" TFT
tft.initR(INITR_144GREENTAB);   // initialize a ST7735S chip, black tab


Did you try pressing RESET after uploading the sketch?

Thanks for the reply!

Yes I made that change, and yes I have tried that as well.
When running the graphics test, it will work once every 10 times I upload it. It will white screen every other time. That why I think it is an faulty display.

Sounds like it could be an intermittent wiring issue. When it does work, does it continue to work, or does it suddenly stop? The graphictest example should do some stuff and then enter a loop where it just inverts the display over and over once per second.

I honestly think it just a bad board. It will work sometimes but the display will seem to flicker. Lately I can not even get the graphics test to even run. I have check connections many times with different wires etc. but nothing seems to works. I have even re-soldered the pins to insure there was a good connection.

Let's try a replacement. Send an email to support@adafruit.com with a link to this thread and they can get you a replacement display.
