I received yesterday 2 TFT and connected them.
The one for the WD is OK. 
The other for the RX but it remains white. 
One video to better explain.

I switch the TFT in case there is a problem on one of them. it's ok
I followed the tracks from the arduino. 

PIN 47 rings on 8 of the HC244
PIN 53 rings on R7
PIN 42, not found
PIN 9 rings on T1

where is the pin 9 on circuit? 

I try with an LCD 20X4, the same my first test : http://www.meteocercal.info/forum/Thread...ght=notice

i download original software without modified values, it's the same problem. 
Perhaps a problem with arduino? 
have you an idea?
thanks
