Thanks guys all your support.
I connected the LED pins, then I've tried out again the adafruit example and everything works now!

Big thanks to all of you!!!

There is a very distinct difference.

There are two pins labeled LED+ and LED-. These are for the backlights - LED+ goes to +3.3v, LED- goes to GND.

This sounds very logical, I'll try that at home, thanks!

If the backlight doesn't come on when power is applied, you may wan't to check your wiring to make sure everything is correct. One thing to note is that the backlight needs to be connected to between 3.0V and 3.3V

The wiring is o.k... at least the power smiley I can measure 5V between the VCC and GND with a multimeter on the pins of the PCB.
But actually I connected it to arduino 5V as the JP1 is open and according to the description in this case 5V must be supplied to the board.

I guess there is no separate pin for backlight and we are talking about the VCC...

Anyway, thanks guys for the sample codes I wouldn't try them out as long as this backlight issue is not solved...

Thanks,

Does the backlight come on?

No there is no backlight!
Is it already bad?

Tom, first of all thanks for your support. I didn't think that somebody will ever look so much into this.

Unfortunately the code you posted doesn't work either.
Am I wrong if I think, that connecting only the VCC should bright up the LCD already?
It just remains dark...

Shall I try to lift it off the PCB?

Thanks,

Hi!

I've recently bought this on ebay:
http://www.ebay.com/itm/261081638769?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649



Unfortunately I'm unable make it work.
I've tried to do it while reading http://learn.adafruit.com/1-8-tft-display
however this obviously doesn't have the same pinout, but I was unable to find any example/hint for this PCB

I linked the VCC to the arduino 5V, so I didn't close JP1.
GND goes to GND
Reset:   PIN8
A0(???): PIN7
SDA:     PIN5
SCK:     PIN4
CS:       PIN6

Then installed the Adafruit_ST7735 library, uploaded the example, then nothing happened.

Please advise smiley-sad

Thanks,

Hi Bill,

thanks for your comment.
By checking the wiring again I managed to make it work!!!

Thanks again,

Hi guys,

I have recently bought a 128x64 LCD from ebay:

http://www.ebay.com/itm/260932724689?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

The interface should be panel B according this and the pinout from the ebay URL:
http://www.arduino.cc/playground/uploads/Code/GLCD_Documentation.pdf

I wired everything, but the LCD displays nothing only the backlit works, I can also change the contrast with the variable resistor.
I'm using the newest library DLed from
http://code.google.com/p/glcd-arduino/downloads/list

I have an UNO. Can you advise something how to proceed?

Thanks,
DEx-
