When i turn on the printer the LCD light up but there isn’t any text. I checked the connections, I loaded the firmware and i adjusted the contrast, but the text isn’t appeared yet. I also disconnected connector of the printhead.
I hope someone can help me
Could you post some High-res pictures of the LCD board and from multiple angles.
Maybe there’s bad solder.

Sorry for the question, but how can i attach an image?
You can go to a site like imgur.com and upload the files. Thereafter you can paste the BBcode it generated.

i have already checked all the solders with a multimeter ant them seems to be good
Some photos of the solder side of the board would be nice =).
And maybe disconnect the LCD and a photo of the component side of the board.
The solders seems ok.
Are you sure the cable was mounted correctly?
I’ve checked it. The jprog connector should be covered by the black cap?
(the red cable is on the left (front view)
and near the reset button in the mainboard)
is the red wire on the left side when you look at it from the front side?
yes, it’s on the left
I’ve checked if the flat cable was good and i found that 5 pins weren’t conncected. i’ve tried to change cable and the lcd seems to work
Nice to hear its working☺
I had to adjust the contrast with a small screwdriver to see the text.
There is a small hole to acces the potentiometer.
maybe this will help other people.
