I bought a brand new TinyScreen and on first time running it I see horizontal color lines dancing across the screen. If I press on the screen it gets brighter and dimmer. I pressed down to make sure it is firmly connected. I stacked TinyProcessr +  USB + TinyAccelerator + TinyScreen (I had to put accelerator in there otherwise the screen doesn't fit, the usb cable gets in the way).

This is now 3rd bad TinyCircuits components I've received. TinyGPS, WiFi and TinyScreen do not work. TinyAccelerometer is the only that is working. I posted in the forums about all these problems and no technical support. Too bad, I really like the form factor and invested $100s into this platform but I've lost count of the amount of hours I've wasted troubleshooting sample code provided by TinyCircuits, reading forum posts, modifying code, not getting anywhere.

After unplugging it and plugging it in a few time it stopped working completely (meaning display stays dead, but the example still runs, no errors).

I used the TinyCircuits-TinyScreen_Lib from manufacturer page.

Can anyone recommend a similar but more reliable platform? TinyCircuits needs to provide tech support and/or improve manufacturing process if they want people to buy their components.

Solved! Thank you Ken for quick response on this.

Change your sample code from this:
TinyScreen display = TinyScreen(TinyScreenPlus);

to this:
TinyScreen display = TinyScreen(TinyScreenDefault);

Works perfectly now.
