I am interested too. As I don't have a response either.

What did you make ? are you using a pi zero W or nor W ?

Your help will be really appreciated.

I'm also up against the clock since I got this to make a gift for my partner's birthday, which is less than a month away. If I don't get it done by then, I'm going to need a refund. Just letting the Admins know (assuming they care enough to check this thread).

I am also having a similar issue where the screen is just completely white when I try to turn the system on. Does my device have to be connected to the internet for it to run properly?

Trying to have this done by Monday for a uni project!

Hello I have recently had the same white screen problem as some other people my screen is similar to the the ones not working and I was wondering how to desolder it to make it a working version

I bought a new one from Amazon, and it worked immediately. For the rest of you, if suggest just purchasing from Amazon, since they actually have a return policy. My screen works great, and I finally get to call quite on this project. I will continue to purchase Adafruit products, but not directly from their site. The customer service is SERIOUSLY lacking. I have been in this business for a long time, and my skill level is NOT the problem. It was a defective product, and I'm just stuck with the loss.

DO NOT BUY FROM ADAFRUIT, BUY FROM AMAZON.

Forgot about Amazon's return policy. I might just do that.

Hello everyone, sorry I was away. So for my part, I just write my image retropie with etcher, then I followed the tutorial Adafruit.
eventually I had the white screen every time.
doing some modifications on all sides is what made my project work:

Write the Retropie image again.

Follow the complete tutorial but at the step:
run sudo nano /boot/config.txt

Do not copy the Adafruit lines.

Add this to the following:

Code: Select all | TOGGLE FULL SIZE
 
#overclocking extreme
arm_freq=1100
core_freq=550
sdram_freq=600
over_voltage=8
over_voltage_sdram=6
force_turbo=1
 
dtparam=spi=on
dtparam=i2c1=on
dtparam=i2c_arm=on
#forcing HDMI output at TFT screen resolution to be able to make the FB copy
#resolution configuration
hdmi_force_hotplug=1
hdmi_cvt=320 240 60 1 0 0 0
hdmi_group=2
hdmi_mode=87
# working config for speed
# 900 Mhz -> 48000000
# 1Ghz -> 35000000
#modification of the speed   
dtoverlay=pitft22,rotate=270,speed=60000000,fps=40




Also make sure your welds are ok.
For me everything worked perfectly after that, I hope I could help you.

I do not thank Adafruit who do nothing and leave their customers without information.

Oxyink thanks for sharing that information I'm gonna attempt this now. I'll let y'all know if it works maybe the tutorials need updated due to some sort of change in software or hardware?

Oxyink, I haven't had the time to look over your code, but do you know if it'll work on the normal Pi Zero?

Well I tried what was suggested for settings and it did show a console display for a moment it was milky white & faded I restarted the pi and after that nothing but white screen. Pretty sure my displays where defective the first one I purchased I have damaged it through troubleshooting I lifted the display from the sticky foam tape to make sure the connection. was good with that ribbon cable and the adhesive on the foam would no longer hold the display securley and now the ribbon cable is torn I'm debating if I even want to give this display third go.

hiya we're still analysing these. we'll replace any bad ones but we dont want to replace them with MORE bad ones and all the TFTs pass test here. so please hold on, there's no guarantee that just because they come from a particular seller that they'll magically work :)

if someone here wants a refund, we can refund the display, but we do not have any guaranteed replacements

I would very much like a refund, but only for the screen. My replacement screen works great, but I wasn't too happy to have to spend an extra $25.. How do I go about this?

I received an email saying that I have been issued a refund for the screen. I just wanted you guys to know that you actually kept me as a customer.
