How to fix white screen of tft touch screen with arduino | TFT unknown driver Fix

[@bonez1305]

Ive not had my TFT long, and was tearing my hair out, all working now, thank you.

[@datamanx5768]

Kudos to you DPV Tech, I spent a few hours looking to resolve the white screen issue, mucking around with install of libraries and so on, your tutorial fixed my issue immediately! Awesome, thank you...

[@arduino9609]

Could you please help me out. I could not find the right identifier. I've tried all of them

[@felixhuxed]

If anyone is having problems with not being able to find the port or connecting to the board I highly recommend getting a new cable, I didn't think it would be a problem to do with the cable since it was making the screen go white, but it was and its all working perfectly fine with a new cable!

[@arduino9609]

Are there any other identifiers? I've tried using all of them, still white screen. I would appreciate if you could take some time and help me out.

[@Sleurhutje]

Just connect the RESET pin of the display to the RST pin of the Arduino. This fixes a proper reset at power up.

[@romandavydov8684]

Yes exactly correct! I have been trying to use software reset command at the beginning of my code. It didn’t work... white screen all the time! As soon as I arrange hardware reset the display started working ! The only disappointing thing here is that u have to use a pin on microcontroller for just that purpose which is stupid loss...

[@brandoc04]

you sir. saved me soooo much, was making a present for my girlfriend was getting too close for comfort!!Thank You!!!

[@admin1b12]

Thank you sir, I couldn't make without your help! It worked!

[@googleuser6875]

I just received a 2.4 inch display and tried to get it going on the Uno. There's not much on the board to identify it but it is a Mcufriend display. It simply had printed on the back of the board "www.mucfriend.com" "tftlcd for arduino uno (spiflash). Running graphictest gives blank screen, serial port output reports: Serial took 0ms to start ID = 0xC0C0 That's it and the screen stays white. Is there some configuration I have to do or is this screen not supported? Any help greatly appreciated.

I am using 3.5 TFT display And I am get Unknown lcd driver chip : 0 Pls help me

[@gunturdanang1179]

same with me

[@mikelee1906]

When I use the 9325 and 9328 I get color and movement but not the correct display. Mostly full pink screen turning to blue back to pink. Should I try other Identifiers? The seller just sent me a folder which contained this file _9341uno. When I try it I get an error: a sub folder of your sketchbook is not a valid library .Does that mean they think it is ID 9341? This was the Zip file they sent 2.4inch_Arduino_ILI9341_V2.0

[@sargrada3893]

hi mate, i did change the identifier the screen work but i have inverted screen i need to read from right to left and some letters are upset down can u help ?

[@MuhammadAhsanKaleem]

Thanks for the video it finally worked!

[@theramendutchman]

Setting the identifier manually hasn't fixed the white screen problem in my case. When I don't change anything, the ID shows up as "0"...

What if the screen shows what it's supposed to when you press the reset button but stays white any other time?

[@jeanfrancoishoussou6293]

hello. sorry for my bad English .I am trying to resolve my white screen problem. I have try all library whithout solution. now i think that it's about my register and i upload LCD_ID redreg library to show a different values of my registers and i found this:Unknow LCD driver C0C0. i am using a 2.4 TFT SPI 240x320 whith arduino uno. I need help.

[@DPVTECHNOLOGY]

Thank you for your comment..Try to replace your driver instead of the driver given in the program.But I did not check that. If it will not work, please try with the following-- www.instructables.com/id/How-to-use-24-inch-TFT-LCD-SPFD5408-with-Arduino-U/

[@Samuel-km5yf]

Still didn't work for me. Maybe my screen is dead. It's white but none of the hex numbers work. Also, it doesn't seem to recognize any driver chip like in your video. You got "6809". All I get is "0". TFT LCD test Using Adafruit 2.8" TFT Arduino Shield Pinout TFT size is 240x320 Unknown LCD driver chip: 0

[@DPVTECHNOLOGY]

Sorry for that. It works for most of the cases. But you try in google. You may get different methods. If it is white, it may not be dead. Most of the cases, we get the hex code as given by Adafruit Industry. But most of the boards come from China and they use different Drivers and therefor this white screen problem occurs. If you woun't get any solution, then buy boards from Adafruit directly from there website(I am not advertising their brand), it will be little costly, but you will not get any problem. You can visit to our "dpvtechnology"website for other components (till now,it is only for india).

[@Samuel-km5yf]

Thanks for the help DPV TECHNOLOGY. After some searching around google, it seems like there are numerous versions of this display that all look almost identical but have different driver chips. Therefore, no one solution will work for them all. You have to try multiple different methods. I think you're right -- if the screen is white, it's probably a sketch and/or library issue and not a hardware issue. My advice to anyone else having the white screen problem -- try the steps in DPV TECHNOLOGY's video and if that doesn't work, keep trying other methods until you find one that works. Google can help find the other methods.
