Display faded & sensitive to touch (ST7735)

[stephenryan2525]

Hey everyone, I have a project that needed a new display so I bought some 1.77" ST7735's Green Tab using hardware SPI to replace the broken 1.8" ST7735

These ones look washed out and only corrects itself for a split second when I reset the Arduino Nano. If I touch anything metallic it's blanks out white. Both new displays behave the same

I've read about some of these displays needing 220/1000ohm resistors on the 5 data lines so I tried both. 1000ohm resistors just shows white static.
220ohm resistors make it look correct but its still touch sensitive

Triple checked wiring, tried switching from 3.3v to 5v VCC, backlight pin with resistors and even disconnected
Tried voltage dividers (510 & 1000ohm)

Any thoughts on what's happening?

This should only be done with power off; inspect the yellow cable, and maybe gently wiggle it or "press it in" (whichever way "in" is). If it is very new, ask for a refund.

Thanks for the suggestion. I tried it with both new displays and they seem fine. I don't think its a fault being for a brief moment when resetting the Arduino it displays properly

I believe sticking with 3.3v is best.
The back light is controlled by PWM do you have an option to increase the PWM signal.
