Nokia 5110 not working

I am having similar problems like in this post here

http://forum.espruino.com/conversations/­267085/#comment12267999

If I fire this code here the display turns on but doesn't display hello world.

Also if i try this tutorial nothing works in the display

Any ideas as to what i am doing wrong.

A5.write(0); // GND
A7.write(1); // VCC

// Setup SPI
var spi = new SPI();
spi.setup({ sck:B1, mosi:B10 });
// Initialise the LCD
var g = require("PCD8544").connect(spi,B13,B14,B­15, function() {
  // When it's initialised, clear it and write some text
  g.clear();
  g.drawString("Hello World!",0,0);
  // send the graphics to the display
  g.flip();
});
